Remove Mold From Shower Caulk or Tile Grout

Mold flourishes in damp spaces and can grow and flourish both inside the home and out. The professionals at RestoPros consistently work to remove mold in restrooms, kitchens, pantries, storm cellars, and even carports – so we have the best tips to help remove mold from shower caulk or tile grout.

How Does Mold Grow on Grout?

One of the most widely recognized spots to discover mold is between tiles, which happens because grout is highly permeable and can keep moisture for long periods of time. Whether they are part of a kitchen backsplash or bathroom accent, tiles as a rule experience a large  amount of moisture. Once in a while an effort is made to dry tiles and the grout between them – but most homeowners take a casual attitude with drying because tiles are thought of as waterproof. In the event that a humid room (including kitchens and bathrooms) has poor ventilation and you don’t run a fan or dehumidifier, the conditions are ideal for mold. Eliminating mold from the grout between tiles can be difficult, but it’s important for several reasons.

Step-by-Step Instructions to Eliminate Mold on Grout

Luckily, there are a few cleaning products that can help to eliminate mold from the grout between tiles. When cleaning the grout between tiles, first check to ensure the cleaning product you use won’t create any harm to that particular sort of tile.

Stay Safe

When you use a cleaning product on the grout, make sure that the room is well ventilated with an open window or fan. Wear waterproof gloves to protect your skin, and where goggles to shield your eyes from spray back.

Materials to Use:


Common chlorine bleach works well to eliminate mold from white grout. Wear a mask along with your goggles and gloves to keep you from breathing in the fumes. Use a hard bristle toothbrush to work the bleach into the grout. Let the bleach sit for about 30 minutes (keep the fan running), at that point wash with warm water.

White Vinegar

Vinegar is a surprising yet common cleaning tool and by and large won’t cause grout staining or corrosion. Using a spray bottle, immerse the moldy area with white vinegar. Let it sit for 30 minutes and afterward scour with a toothbrush, being careful not to harm the grout itself. Brush twice and let sit for an additional 30 minutes. Wash with warm water.

Baking Soda

Baking soda is also a favorite household cleaner. To make a paste that you can spread over mold to lift it, mix together 1/2 cup of baking soda and a few teaspoons of water. Stir the mix until you have an effectively spreadable consistency. Apply the baking soda paste over the moldy grout, let sit for 10 minutes, at that point clean the mold away with a toothbrush. Wash with water.

Baking Soda + Hydrogen Peroxide

Apply a thick baking soda paste to the area affected by mold. Cautiously pour hydrogen peroxide over the baking soda paste so it starts to bubble, which will help loosen the mold. Scour the bubbling paste using a firm toothbrush. Afterwards wash the paste and mold away with water.
