How to clean mold in a shower

The bathroom contains all of the ideal ingredients for a concoction of molds and mildews: it’s damp, generally dark and generates vast amounts of bacteria-laden water droplets that mold and mildew love. Shower mildew is generally red or green, depending on the species of the fungi. Black mold is considered to be the most toxic mold, causing health problems such as asthma and other respiratory problems. Although a plethora of special mildew and mold cleaning products glut the supermarket shelves, you can remove shower mold with a few basic household products.

Cleaning shower mold requires a good amount of elbow grease — this means you’ll be scrubbing a lot — as well as an acidic disinfectant to kill the mold spores. Household white vinegar consists of acetic acid, a mild nontoxic acid that kills most shower mold and mildew. Chlorine bleach kills mold and mildew but produces harmful fumes and skin reactions for those with sensitive skin. Try using vinegar to remove mold and mildew before moving on to the more caustic materials.

For removal of shower mold and bathtub mold, mix equal amounts of white vinegar — acetic acid — and hot water into a bucket. Wash the walls of the shower unit and the tub, then rinse it off when you’re done. In stubborn areas, apply undiluted vinegar. Vinegar also removes hard water deposits and stains. Several applications might be required to completely clean mold and water stains from the shower and tub.

For removing shower head mold and mold in tile grout, add just enough baking soda to create a paste. Smooth the paste onto the affected areas. Allow it to sit for a minute or two, then scrub it with a stiff toothbrush or nylon brush and rinse it off with water.

Severe stains can be treated with diluted chlorine bleach, but wear rubber gloves to protect your skin, and open a window to provide sufficient ventilation. Mold cleanup is vigorous work. You might not see instantaneous results for very severe cases. Apply the solutions several times if necessary.

The old proverb “an ounce of prevention is worth a pound of cure” rings true for bathroom mold. To prevent shower mold from forming, run the ventilation fan after every shower. Maintain a clean environment by regularly scrubbing the walls, tub, shower and shower head with a bleach or vinegar solution. In the event of a stubborn case of mold, consult a professional.

Animandel – When you’re trying to figure out how to get rid of mold without the heavy odors of cleaners there are ways. If you are concerned about fumes then try the baking soda as mentioned in the article. Using the baking soda paste will require more scrubbing than using a liquid would, but the baking soda is easier on the nose. It’s even less obnoxious than the vinegar. Animandel February 11, 2014

I have used the chlorine bleach for shower mold removal and it worked well. However, the smell and the fumes were overwhelming. I thought I was going to succumb before the mold did.

After that experience, I decided to use vinegar and it works well, also. I’m not sure which is better, bleach or vinegar. However, because of my sensitivity to the bleach fumes, I always use vinegar now. Sporkasia February 10, 2014

I worked at hotel one summer in the housekeeping department. One of our major projects at the beginning of the season was removing mold from the tile grout in the bathrooms. This was a seasonal hotel at a resort, so getting the rooms ready at the beginning of each season was a challenge.

Anyway, the manager gave us a spray bottle and bleach to mix with water and then spray on the mold. We were also given toothbrushes to scrub the grout. Removing the mold took a bit of elbow grease and you had to work at removing it all, but it wasn’t overly difficult with our mold killer tools.

Still, scrubbing mold covered showers wasn’t one of my most enjoyable projects of the summer. Fortunately, the summer improved as it went along.

Showers are notorious for their gunk and funk. Sure, there are some super sparkly perfect showers in this world but they are few and far between. Life happens and cleaning the shower ends up fairly low on most people’s list.

Enter black mold in the shower. Uggg.

Don’t worry. It happens to pretty much all of us. Even me. Yes, you read that right. I fight the shower mold fight weekly. Whoever thought that natural stone tiles in the shower was a good idea thought wrong.

Trust me when I saw that I have tried EVERYTHING in the battle against black mold in the shower. I’m a pretty savvy DIY cleaning guru as well as a certified mold inspector. You’d think I would have this down to a science. Ha. Yeah – nope. Every shower is different which is why there is no one size fits all approach to how to get rid of mold in the shower.

But never fear – I will give you a handful of shower mold removal options that WILL work. You just have to play around and find the one that works in your shower.

How to clean mold in a shower

Why Do I Have Mold In My Shower?

It’s very common for mold to be found in the shower. There is lots of water and humidity in the bathroom which mold just adores.

Frequently running water in the shower creates wet surfaces and puddles of water. If you don’t dry this moisture out quickly it can easily lead to mold growth.

On top of this, when the water in the bathroom does dry out it evaporates into the air and increases the humidity. Steam from the shower or a hot bath also makes the bathroom more humid. Since bathrooms are often not well ventilated the humidity tends to hang around and wet surfaces take a long time to dry out. Enter mold.

Another reason mold grows in the shower is because grime from body oils and soap scum which is washed off and onto the shower or tub create a food source for mold to feed on.

Basically, if mold were to have a choice vacation destination it would be the shower. Soooo inviting.

Where Does Mold Grow In My Shower?

  • Mold can grow in the grout. That is one of it’s favorite places.
  • It can grow inside the window frame if your window is IN the shower like mine is.
  • It can grow around the drain and on the drain plug.
  • Mold can grow on the shower caulking.
  • It can grow in the door tracks if you have doors.
  • Mold can grow under shampoo bottles, bars of soap, shaving cream bottles, etc…
  • While not technically a part of the shower, mold can grow on a shower curtain.

Mold can also grow behind shower tiles and on the wall but this is due to a leak behind the shower and not from water in the shower typically. The exception is if your grout is old and cracking. Then water can seep behind the shower tiles allowing mold to grow.

Is Shower Mold Toxic?

Due to the way bathrooms and showers are constructed today, the black mold you see in your shower is less likely to be the really hazardous type of mold. This is because your shower areas and surfaces don’t have cellulose (found in things like wood, fiberboard, lint, paper, and dust) which is required for most of the really hazardous types of mold to grow.

That is not to say that one of the more toxic molds can’t ever grow in your shower. They can. If you have a bigger issue in your bathroom or home and THOSE spores have infiltrated your shower then your shower can become a breeding ground for some really bad mold. But regular ol’ mold in the shower… usually more allergenic than anything.

Can You Get Sick From Mold In The Shower?

You can get sick from any mold thanks to your genetic makeup, your current health, and many additional factors. Don’t assume that since mold in the shower isn’t usually super toxic that you can’t have health issues from it. Try to prevent shower mold and of course remove it once you see it growing.

Is Shower Mold Always Black Mold?

Nope. There are many colors of mold and shower mold can be pink, green, brown, or even grey.

7 Ways To Prevent Shower Mold

  1. Practice good ventilation. Open the bathroom window when showering. Turn on the exhaust fan when showering and leave it on for 30 minutes afterwards. Keep the bathroom door open when showering if possible.
  2. Shower drains contain biofilm and cellulose materials such as soap scum, body hairs, and oils and lots of moisture so they can be a breeding ground for black mold. It is important to keep drains open and clear of cellulose materials. Remove any hair after showering and pour a little vinegar down the drain weekly to keep the drain clean and prevent mold spores from developing.
  3. After showering wipe down the entire shower including all your shampoo and soap bottle.
  4. Once a week spray the shower with EC3 Mold Solution Spray to kill any new mold spores that may be trying to root.
  5. Clean your shower from top to bottom every 14 days at a minimum. Weekly is better but no one has time for that! So shoot for every two weeks.
  6. If possible, DO NOT USE one of those suction cup non-slip mats in the shower. Those are a mold magnet.
  7. Treat your shower with Endurance BioBarrier every 6 months to prevent mold growth. You can read how and why Endurance BioBarrier works here.

How To Get Rid Of Mold In The Shower

Before we get to the various ways to clean a moldy shower, I want to provide you with links to posts that I have written about some of the specific mold removal products. This will give you a better idea about why I am recommending them.

I think it is also important for you to know why I do NOT recommend cleaning mold with bleach. You need to read that post but in short, it causes MORE mold growth and doesn’t actually kill mold.

Ready? Let’s go area by area.

How to remove mold from shower caulking

The ideal thing you can do to remove black mold in shower caulking is to remove the caulking altogether and apply new high-quality mold resistant caulking like this one. This is important because a good mold resistant caulk will help prevent water damage and mold from happening behind your tile and shower walls.

This is actually easier than it sounds. Even I can handle doing this. While it doesn’t take long to actually remove and replace the shower caulk, it does require you to let it dry properly before using your shower again.

Don’t want to remove and replace the shower caulk? You can try this mold removal method but it is time consuming and usually doesn’t get more than 50-60% of the mold.

How to clean mold in a shower

Spotting mold in your shower feels like a disaster, but it happens—especially if your bathroom doesn’t get much air-flow. Mold is a type of fungus that can grow in moist spaces. “Since showers are typically used multiple times a day, it’s difficult for their surfaces to dry fully between uses,” says James Conner, vice president of operations at Neighborly, the parent organization of house-cleaning company Molly Maid. Luckily, having a moldy shower doesn’t mean you’re doomed. You just need the right techniques and tools to squelch the mold.

First of all, Conner says the best way to combat shower mold is to take a preventative approach. If you regularly wipe down surfaces and dry them off after a shower, leave your shower door or curtain open to allow airflow, and/or run an exhaust fan to decrease your chances of seeing mold pop up. Cleaning often is also important.

“If you’re able to wipe down and dry off the tub, shower liner, and tile each time you bathe, you won’t need to deep clean your shower with bleach or other harsh cleaners more than once a month,” he says. “If your shower curtain is washable, wash it about once per month. And if your plastic shower liner can be put in the washing machine, wash it one or two times a month. You can even add a towel or two to the washing machine with the liner to help ‘scrub’ the liner.”

But for those times when you already have a moldy mess in the shower, here’s exactly how he says to tackle it.

Here’s what you need to clean a moldy shower

How to clean mold in a shower

If you see mold in your shower, Conner says the best way to go after it is with a cleaning product formulated to remove mold. This option can kill 99.9 percent of household bacteria, as well as get rid of mold and mildew. “If mold does appear on your shower curtain, grout, tile, or fixtures, there are a few ways to get rid of it. Any cleaning product that specifies effectiveness against mold will work, as will a diluted bleach mixture,” he says.

If you want to clean the mold or mildew with bleach, Conner has a process that works like a charm. “Start the bathtub-cleaning process by filling a spray bottle with hot water and four tablespoons of bleach,” he says. “Spray this solution onto the affected areas, and allow it to soak in. While the bleach is soaking in, sprinkle baking soda throughout the tub.”

After you treat the mold or mildew with the cleaning spray or bleach mixture, scrub it away with a nylon cleaning brush. “Fill a bucket with a half-gallon of hot water and two tablespoons of dish soap. Then dip a scrub sponge or a stiff nylon brush into the bucket, and scrub all bathtub surfaces,” he says. “Use the bucket to periodically rinse out the sponge or brush.”

3. Arm & Hammer Baking Soda, $16 for Two 5-Pound Bags

If you need some extra help cleaning your tub, Conner says to use baking soda. “When cleaning especially dirty tubs or stains, sprinkle baking soda directly onto the sponge or brush after dipping it in your bucket solution, and scrub hard,” he says. “Once you’re satisfied and the tub looks clean, use the bathtub hand sprayer or the water in the bucket to rinse the tub. Always be sure to dry off your bathroom surfaces when you’re done.”

Effective homemade mold cleaner spray and other DIY tips for cleaning the bathtub and tile in the shower, using natural ingredients like vinegar, baking soda and essential oils. Includes a recipe for a DIY natural shower cleaner for mold prevention.

How to clean mold in a shower

The gleaming tile. The shiny new fixtures. The spotless shower. When you spend good money redecorating a bathroom, you can get a little obsessive about keeping it clean.

I know because I’ve been there.

We did a partial remodel in our bathroom by putting in new tile in the shower and new porcelain over the old bathtub. I’m bound and determined to make sure that mold and mildew don’t take residence in there!

Not only is mold ugly and embarrassing, it can be a health hazard, causing asthma attacks, nasal congestion and headaches.

So how do you keep mold and mildew from growing in your shower?

The best place to start is prevention. Mold prevention in the bathroom is tricky but use the tips below to try to keep mold from growing in your shower in the first place. If mold does show up in the shower, attack it immediately using the natural mold cleaning tips I outline below.

Natural Mold Cleaning Tips

Here are a few of my favorite natural mold cleaning tips – using only non-toxic ingredients like vinegar and baking soda.

I may receive commissions from purchases made through links in this article. Full Disclosure

Natural mold prevention:

  • Make sure the shower area is well-ventilated – turn on the fan and open the windows and doors!
  • Use a squeegee to take excess water off of the shower walls.
  • Wipe down problem areas like corners and ledges with a dry cloth. Mold needs a wet environment to grow so keep things dry!
  • Shake out shower curtain after each shower. Wash or replace shower curtain frequently.
  • Make your own homemade bathroom cleaner spray using vinegar and the essential oils to prevent mold (see DIY shower cleaner recipe below)

Natural mold cleaning:

  • Spray mold with straight vinegar to kill spores.
  • Mix up a paste of baking soda or borax (a naturally occurring mineral) and scrub with a toothbrush. Use caution if you use borax – it can be harmful if ingested.
  • To bleach mold and mildew stains, mix 1/4 cup hydrogen peroxide with 1/2 cup water in a spray bottle. Spray stains with solution, scrub it in a bit and then leave to dry.
  • Once mold has taken hold in your shower, it may not be possible to scrub it away. Replacing mold stained caulk or grout may be your only option in some cases.

Homemade Mold Cleaner Spray

Use this spray regularly to help prevent mold from taking hold in your shower.

1 big squirt (approx 2 tablespoons) liquid castile soap (like Dr. Bronner’s) or eco-friendly dish soap

20 drops of antiseptic essential oil like tea tree or grapefruit

Mix all ingredients together in a spray bottle. Spray liberally over entire shower area. Leave for 3 to 5 minutes, then wipe area dry.

Mold Cleanup

Who should do the cleanup depends on a number of factors. One consideration is the size of the mold problem. If the moldy area is less than about 10 square feet (less than roughly a 3 ft. by 3 ft. patch), in most cases, you can handle the job yourself, follow the Mold Cleanup Tips and Techniques. However:

  • If there has been a lot of water damage, and/or mold growth covers more than 10 square feet, consult EPA guide Mold Remediation in Schools and Commercial Buildings. Although focused on schools and commercial buildings, this document is applicable to other building types.
  • If you choose to hire a contractor (or other professional service provider) to do the cleanup, make sure the contractor has experience cleaning up mold. Check references and ask the contractor to follow the recommendations in EPA guide Mold Remediation in Schools and Commercial Buildings, the guidelines of the American Conference of Governmental Industrial Hygenists (ACGIH), or other guidelines from professional or government organizations.
  • If you suspect that the heating/ventilation/air conditioning (HVAC) system may be contaminated with mold (it is part of an identified moisture problem, for instance, or there is mold near the intake to the system), consult EPA guide Should You Have the Air Ducts in Your Home Cleaned? before taking further action. Do not run the HVAC system if you know or suspect that it is contaminated with mold – it could spread mold throughout the building.
  • If the water and/or mold damage was caused by sewage or other contaminated water, then call in a professional who has experience cleaning and fixing buildings damaged by contaminated water.
  • If you have health concerns, consult a health professional before starting cleanup.*

Tips and Techniques

The tips and techniques presented in this section will help you clean up your mold problem. Professional cleaners or remediators may use methods not covered in this publication. Please note that mold may cause staining and cosmetic damage. It may not be possible to clean an item so that its original appearance is restored.

  • Fix plumbing leaks and other water problems as soon as possible. Dry all items completely.
  • Scrub mold off hard surfaces with detergent and water, and dry completely.
  • Absorbent or porous materials, such as ceiling tiles and carpet, may have to be thrown away if they become moldy. Mold can grow on or fill in the empty spaces and crevices of porous materials, so the mold may be difficult or impossible to remove completely.
  • Avoid exposing yourself or others to mold. See discussions:
    • What to Wear When Cleaning Moldy Areas
    • Hidden Mold

  • Do not paint or caulk moldy surfaces. Clean up the mold and dry the surfaces before painting. Paint applied over moldy surfaces is likely to peel.
  • If you are unsure about how to clean an item, or if the item is expensive or of sentimental value, you may wish to consult a specialist. Specialists in furniture repair, restoration, painting, art restoration and conservation, carpet and rug cleaning, water damage, and fire or water restoration are commonly listed in phone books. Be sure to ask for and check references. Look for specialists who are affiliated with professional organizations.*

Bathroom Tip

Places that are often or always damp can be hard to maintain completely free of mold. If there’s some mold in the shower or elsewhere in the bathroom that seems to reappear, increasing ventilation (running a fan or opening a window) and cleaning more frequently will usually prevent mold from recurring, or at least keep the mold to a minimum.

Floods and Flooding

During a flood cleanup, the indoor air quality in your home or office may appear to be the least of your problems. However, failure to remove contaminated materials and to reduce moisture and humidity can present serious long-term health risks. Standing water and wet materials are a breeding ground for microorganisms, such as viruses, bacteria, and mold. They can cause disease, trigger allergic reactions, and continue to damage materials long after the flood.

How to Remove Mold and Mildew from Shower Doors

Soap scum may be unsightly, but it’s not going to hurt you. Mildew, on the other hand, just might. It’s that usually black (but sometimes pink or green) growth you sometimes see around the edges of shower doors, where the glass meets the frame, and it’s a fungus. It can cause illness, especially in people allergic to mold. And it’s ugly.

“Mold” and “mildew” actually refer to the same growth. “Mold” is the fungus, and “mildew” is what you get when that fungus builds up.

Whatever you call it, you can get rid of it using a solution with either chlorine or hydrogen peroxide in it. Both will kill the mold. Just spray or wipe it on — you don’t need to scrub. If you have a bigger mold problem, you might need to repeat the application a couple of times.

If, however, the mildew creeps behind the caulk, you may have to replace it. Once it gets back there (or into the grout anywhere else in the bathroom), it’s very hard to get rid of.

To prevent mildew’s return, leave the shower door open between uses so air can circulate, and consider using an anti-mildew spray after each shower.

Up next: The spots that are “hard” to wipe off.

Mold, and its early-stage counterpart, mildew, are forms of fungi that grow in damp areas and replicate quickly. Mold and mildew can cause allergies and respiratory conditions, and sometimes more serious health problems that affect the nervous system. Therefore, you need to get rid of mold and mildew quickly. Bathroom surfaces, particularly tile around the tub and shower, tend to be mold and mildew incubators because of the heat and moisture that accumulate there. But you can usually remove the unwanted substances easily using white vinegar in combination with baking soda as a scouring agent.

Fill a small spray bottle with white vinegar.

Spray the affected areas — including tile, grout, painted walls, and any porcelain or ceramic surfaces — liberally with vinegar. Let it sit for one to two hours.

Scrub the mold and mildew away with a damp microfiber cloth. Scrub tiling grout or hard-to-reach corners and crevices with a stiff-bristle toothbrush. Rinse with water.

Make a paste of 3 parts baking soda to 1 part water. Apply the paste to any hard-to-remove traces of mildew or mold. Spray with vinegar, and scrub with a damp microfiber cloth, scouring pad or stiff-bristle toothbrush, depending on the severity of the mold or mildew.

Rinse the affected areas with water. Repeat Step 4 if necessary.

Things You Will Need

Scouring pad or microfiber cloth

Stiff bristle toothbrush

To prevent further problems with mold and mildew, keep your bathroom dry and well-ventilated. During and after a shower or bath, open a window or use the vent fan, and use a squeegee or mop to get rid of excess water buildup. Likewise, try to keep the sink area dry after use.

Keep the bathroom well-ventilated when working with vinegar and baking soda together in large quantities; the combination releases carbon dioxide.

A microfiber cloth is soft on the surface and highly absorbent. However, in instances where mold and mildew is very hard to scrub off, try a stronger scouring pad instead.

Warning

If mildew and mold in tile grouting does not go away after you scrub with white vinegar and baking soda, clean the affected surfaces with hydrogen peroxide in a spray bottle. Be careful not to mix hydrogen peroxide and vinegar, because the result can be toxic.

If vinegar and hydrogen peroxide do not work, which may be the case with highly affected grouting, try a solution of 3 parts water to 1 part bleach. If you do this, make sure your room is well-ventilated, wear gloves to protect your skin and be cautious not to mix bleach with other cleaning agents.
