Cleaning Mold: How to Remove Mold From Shower Wall Grout

Grout gaps and cracks that develop over time hold a lot of debris that these bugs eat.

Make sure the crevices are sealed. Seal these cracks with silicone-based sealants. The silicone-based sealants are strong, waterproof, and they last for a long time.

Whats the best part? Silicone sealants cant be chewed through by bugs.

There are loose floor tiles with broken grout between the tiles that need to be repaired.

Bugs like centipedes can hide in cracks and gaps in the bathroom floor when these cracks and gaps become wider.

You should also seal the cracks in the bathroom windows.

Cracks can serve as entry points for flies which are attracted by dampness.

Install window screens on the windows as well. This will keep the bugs out of your bathroom and house.

These materials are smooth, allowing you to wipe the surface clean with a rag after applying the solution.

You can spray every surface is in the bathroom, including the inside of the shower and the tub surround or walls.

It should also work on the grout and caulk. However, you may need to scrub those areas after cleaning the non-porous surface.

If you do not have a spray bottle, pour the cleaning mixture into a bucket. Use a disposable towel or old rag to apply the solution on the affected surfaces.

Allow the cleaning mixture to set for several minutes and then wipe clean with cloths or rags. As you wipe the surface, the mold should come right off. Replace or rinse the cloth or rag when it gets dirty.

In some areas, the mold may remain. To get the tough patches of mold, spray more of the cleaning solution and then scrub clean with an old toothbrush or scrubby brush.

When you are satisfied with the mold removal, use the baking soda solution to disinfect all the surfaces and kill any microscopic mold spores.

  • Mix one part bleach to four parts water in a spray bottle
  • Spray the affected area, wait for about 30 minutes, then scrub vigorously with a brush
  • Rinse with cool, clear water. Repeat the process, if necessary.

Method 2:

  • Use a stiff bristle toothbrush to scrub bleach directly onto the moldy grout
  • Let the bleach sit for about 15-30 minutes, then rinse with warm water. Repeat as needed.


  • Bleach causes fading and discoloration, so it should not be used on colored tiles or colored grout
  • The fumes from bleach can be irritating to the eyes, skin and respiratory tract, so you need to wear a mask, safety glasses, and rubber gloves when using it. Keep the room well ventilated during the cleaning process and let the windows open for a couple of hours afterwards to make sure that all harmful fumes have left the room.

You cant, of course, but you can reduce the dampness there is a big difference between getting wet and staying permanently wet.

Here are some simple, yet highly efficient measures you can take to lower the humidity in your bathroom, kitchen, and other wet areas of your home and prevent mold growth:

1. Keep doors and windows open for as long as possible to ensure proper air flow within the home:

  • Let the bathroom window stay open for at least 15 minutes after you turn the shower off, so that excess moisture can move out of the room rather than condense on the walls and tiles
  • Leave the shower door open when the shower is not in use
  • Keep the kitchen windows open while cooking to allow the steam to escape
  • Ventilate the laundry room, basement, and attic as often as possible.

8. Fix leaky faucets and showerheads to remove the source of excess moisture in your bathroom and kitchen

Shower curtains are difficult to keep clean. Soap and scum cling to the surface, increasing the chance of mildew and mold growth.

For minor mold growth on vinyl or plastic, scrub the curtains with baking soda and water. Spraying a little vinegar on the curtains afterward helps protect against future growth.

Washing fabric or cloth curtains in the washing machine with some detergent and a half cup of baking soda may remove mold. Soaking the fabric in a bucket filled with vinegar may also work.

For severe mold growth, toss the curtains. Even if you remove the mold, the stains will likely remain.

If You Suspect Black Mold Consult A Professional

Most mold that grows in a bathroom is harmless. Black mold, however, is something that should only be handled by a professional mold removal team. If you suspect black mold, or you believe that the mold has become a more serious issue, consult a professional before you begin removal efforts. Especially if you live in a rental property, it is important to notify your property managers of the potential black mold.

How To Remove Mold From Bathroom Grout And Caulk

How To Remove Mold And Mildew From Shower Tile Grout

Removing mold from smooth surfaces is relatively easy but grout and caulk provide a challenge. These materials are porous, allowing the fungus and bacteria to penetrate below the outersurface.

Use the previous technique of spraying the solution and then wiping it clean to remove the mold that appears on the surface. Next, respray the grout and scrub with an old toothbrush, scrubbing pad, or scrubbing brush.

If the mold remains, try using a combination of baking soda and water. Use the toothbrush to really get into the pores of the grout.

These steps should remove as much mold as possible. If the grout or caulk remains stained, there is one more option. You can re-grout and re-caulk the affected areas.

When adding new caulk, consider using Polyseamseal Tub and Tile Adhesive Caulk as it contains mildewcide, allowing the caulk to resist mold and mildew growth.

Does Vinegar Hurt Grout

Vinegar is mildly acidic with a pH level around 2.5. Frequent full-strength applications of distilled white vinegar containing 5% to 6% acetic acid followed by hard scrubbing may cause grout to break down. However, natural cleaning solutions such as vinegar and borax are still much less harsh than chlorine bleach.

Health Risk Of Black Mold

Mold is gross to look at but what is the real risk? It turns out that mildew and mold growth in the bathroom does not pose a serious health crisis unless the mold spores begin to spreadthrough the rest of the house.

Some types of mold become a danger when allowed to spread on surfaces with cellulose, which is found in wood and wood-derived materials such as paper and fiberboard.

If the mold penetrates the walls, floorboards, and rafters, the toxic mold may develop.

In bathrooms, the mold is more likely to cause minor respiratory issues in some individuals. Potential symptoms include:

  • Itchy eyes
  • Rashes
  • Skin irritation

During a severe reaction, you may also find it difficult to take deep breaths. If you detect these signs, remove mold and consider having your property inspected for the spread of moldthrough other areas.

While mold is rarely a danger, remove it before it has the chance to spread. It can easily travel through air ducts and settle in rooms throughout the house.

How To Remove Mold From The Shower

No one likes the sight of mold. Unfortunately, the inside of your shower is the perfect breeding ground for mold spores.

The wet conditions provide mold with the optimal setting to spread and thrive. While this growth is rarely a direct threat to your health, it can reach other areas when left untreated.

Bleach or ammonia may help clean up some of the mess but these ingredients rarely provide a complete solution. They are also potentially harmful to the environment and your health.

Instead of using toxic chemicals, there are many safe ingredients. With the right home remedy, you will no longer need to shower surrounded by mold.

To keep your bathroom clean, sanitary, and mold-free, use the following natural mold removal solutions.

Baking Soda Plus Hydrogen Peroxide

Apply a thick baking soda paste to the area affected by mold. Spray or carefully pour hydrogen peroxide over the baking soda paste so it begins to fizz, which will help loosen the mold further. Scrub the fizzing paste using a stiff bristle brush, then rinse the paste and mold away with water. Repeat as needed.

Tip: If there’s mold on the caulk that seals around your tub, faucet, sink or toilet, the safest thing to do is remove the caulking. Sterilize the area with bleach or distilled white vinegar and dry it thoroughly before replacing the caulk. Opt for a mildew-resistant caulk to inhibit the growth of future mold. Some mold problems can’t be tackled with home remedies or commercial cleaners found at your local store. If you’re facing stubborn grout mold or too much mold to handle alone, call the pros at ServiceMaster Clean for complete mold removal from any area.
