How To Remove Mold From Shower Grout

Grout Is A Highly Porous Material & Susceptible To Mold Growth

Cleaning Mold: How to Remove Mold From Shower Wall Grout

In addition to having an environment that is ideal for mold growth, grout is naturally a very porous material. When water sits on the surface of the grout for extended periods of time, mold quickly begins to form. Certain types of grout are made to be mold-resistant. Unless you build your home or remodel your bathroom, however, you are unlikely to have this type of grout in your shower.

How To Remove Mold From Non

After cleaning the bathroom, it is time to get to work with the homemade cleaning solutions. Start with the shower, tub, and other non-porous surfaces.

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

Choose one of the cleaning mixtures discussed and pour it into a spray bottle. Spray the entire surface that you want to clean until it is evenly coated but avoid spraying enough to create pools of liquid.

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.

How To Remove Mold With Vinegar

Vinegar is one of the most effective natural cleaning agents. Due to its acidic nature, it creates an environment that inhibits bacteria growth.

At the first signs of mold on the grout, mix equal parts distilled white vinegar and water in a spray bottle and generously spray the affected area. Wait for 30 minutes, then scrub the surfaces with a bristle brush and rinse with warm water. For best results, repeat the process several times.

You can use tree tea oil in roughly the same way use two teaspoons of the products to every cup of water you add in the spray bottle, spray the moldy surfaces, and wait for several hours before rinsing with clear water.

Make sure you keep the windows open to ensure good air circulation and counter the strong smell of the vinegar or the tea tree oil.

If the mold growth is extensive, however, these natural products wont be strong enough to remove it.

If vinegar and tea tree oil arent doing the trick, then its time to move onto another homemade shower mold cleaner: baking soda. This grout cleaner is fantastic when you need to remove a mildew stain that wont disappear. Baking soda can also be used with vinegar in the washing machine to remove mold and mildew from a shower curtain.

  • Toothbrush or bristle brush

Start by creating a thick paste by adding water to the baking soda and blending it well. Add the baking soda paste to the shower walls, getting in between the grooves of the tile. Scrub the paste into the grout lines, using a toothbrush to work the cleaner deep into the crevices and cracks.

Next, spray some vinegar over the baking soda paste and wait for the bubbling to stop. After the fizzing has subsided, continue scrubbing the tile grout until visibly clean. Rinse with clean water and dry.

How To Remove Mold And Mildew From Shower Tile Grout ...

Many sources advise using baking soda and vinegar as a natural agent to remove mold from the shower grout. I have decided to test this advice out, and the results were unexpected.

Optimum pH

The primary reason why baking soda and vinegar works well in combating mold lies in their pH. The mold usually grows in pH 3 7 . If you have black mold in shower grout, the chances are that you are dealing with the Stachybotrys Chartarum. Its optimal pH for growth is 5.6-6.0 . Because of that, to get rid of the mold and keep it away, it helps to use ingredients that change the pH of the infested area, creating a hostile environment for the mold.


I know that using baking soda and vinegar is a widely spread tip however, I have seen various alternatives of how to use those ingredients, e.g.:

Baking Soda + Water Baking Soda + 3% Hydrogen Peroxide Baking Soda + White Vinegar Baking Soda + White Vinegar + 3% Hydrogen Peroxide Vinegar

But what is the best option? I have tested all the combinations mentioned above, leaving them to sit in the grout for about 20-30 minutes. First, I have started with 30 minutes, but then I have shortened it to 20 minutes, and the results seemed similar. The findings were quite surprising.

Also, vinegar shouldnt be used on, e.g., natural stone, so if you choose to use it, make sure that your tiles are suitable for acid cleaning agents.

Natural Remedies For Dealing With Mold In The Shower

For decades, homeowners used bleach for cleaning the bathroom and disinfecting surfaces.

Using bleach may remove mold stains from non-porous materials such as porcelain tubs, showers, and toilets but does not help remove mold on grout or wood.

Bleach is also ineffective for killing mold, bacteria, and fungus. It neutralizes some harmful particles and helps remove stains but does not truly kill the mold.

Luckily, there are alternative solutions. You can make powerful cleaning agents that work on almost any surface, including:

  • Tubs and shower surrounds
  • Metal fixtures
  • Walls and ceilings

While the cleaning solution that you mix should work on everything, the way that you apply the mixture depends on the type of surface. You can wipe non-porous surfaces clean but may need a brush for scrubbing mold from grout and wood.

First, you need to create a cleaning mixture. These options require ingredients that you already likely have in the bathroom or kitchen, including vinegar, hydrogen peroxide, tea tree oil, and baking soda.

These are just a few of the home remedies for getting rid of mold but they are among the most effective.
