Among the types of fungus and mildew we have to deal with in our household, black mold is probably the most harmful and injurious to human health. Along with being concerned and cleaning our house regularly, knowing how to remove black mold is equally important to ensure a healthy lifestyle.


What Causes Black Mold in Shower

Before we can get into cleaning, we need to learn what causes black mold in the shower in the first place. Mold and fungi can grow in your house because of a number of reasons. But the most common of them is moisture and humidity.

Since showers and bathrooms have the highest chance of moisture due to the constant use of water, it is ideal for black mold to grow in the shower.

On the other hand, humidity tends to increase in bathrooms often because of the evaporation of water. Steam from a hot bath can also make the shower more humid than usual.

Since showers aren’t usually well-ventilated, it takes a long time for the water to dry and the vapor tends to hang around the wet surfaces. Combining them all, it’s an inviting situation for the molds to grow; especially black mold.

You can check for black mold in your shower by looking in your basin, bathtub, shower, drains, tiles, and grout. These are the places where water runs the most and increases the black mold’s growing possibility.

How Do I Clean Black Mold in Shower Silicone?

Among all of the miseries, remedies, and guidelines, many people ask this; How to get rid of black mold in shower caulk?

Shower caulk, also called shower silicone or shower sealant, is one place mold and fungi love to grow. And it gets worse because black mold doesn’t just grow in there, it settles and absorbs into the shower silicone because of the place’s rubbery type surface.

Nonetheless, you can clean black mold in shower silicone using vinegar to kill black mold, using hydrogen peroxide, or applying bleach. For further solutions, you can also remove black mold in shower caulk with Ammonia.

Yes, ammonia can be a powerful cleaning agent with a little tweak to make it safer for use.

You will need:

  • Rubber gloves
  • Respirator
  • Ammonia
  • Water
  • Spray bottle
  • Small brush
  • Paper towels

Before anything, keep in mind that ammonia is a powerful toxic substance and it should be treated with extra caution. So wear gloves and a respirator first, and make sure the shower is as ventilated as possible.

Combine equal parts of ammonia and water into a spray bottle, and mix them well to create your DIY cleaning solution. Spray the mixture over the caulk area affected by black mold. After you have covered the whole area of fungus, let the ammonia solution work for at least 15 minutes.

Once you’re done, use a small brush or a toothbrush to scrub the area to kill black mold. Know that ammonia is a potent cleaner and thus, it can have effects on porous surfaces like shower caulk. So be careful about this part of the cleaning process and gently scrub the moldy area. Afterward, use paper towels to wipe clean the surface to remove everything.

If black mold has penetrated too deep into the shower silicone (there is a chance if the mold has been sitting for a long time), it may become impossible to clean it with any of the solutions.

In that case, our recommendation is to remove and replace the caulk with a new application. You can easily get caulk tubes in your local supermarket, or you can take professional help.
