How to Clean Mold From Bathroom Grout & Tiles

Mold accumulates on bathroom tile and grout because it thrives in moist, humid conditions. When you do not treat the mould immediately, it will continue to grow on the tiles. Instead of using harsh chemicals to remove the mould from the tile and grout, you can use items you have around your home. This often winds up saving you money as well.

Scrub the tile with a bristled scrub brush. Wet the brush and scrub on the tile to loosen the mould.

Combine 1 cup of white vinegar with 1 cup of distilled water in a clean spray bottle. Add 1 tbsp of lemon juice and shake to mix the ingredients.

Spray the solution onto the mould. Allow it to sit for 20 minutes, then scrub the tile with a damp washcloth.

Dry the tile with a clean towel. Repeat the process if you still notice mould.

Combine ¼ cup of hydrogen peroxide with ½ cup of water in a spray bottle. Shake the bottle to mix the ingredients.

Spray the solution onto the grout. Allow it to sit for 10 to 15 minutes and then scrub with a bristled scrub brush.

Rinse the grout with clean water, then dry it off with a clean towel. If the mould remains on the grout, you can treat it with baking soda.

Combine an equal amount of water and baking soda in a bowl. Apply the paste to the mould or mildew stains and scrub with a bristled brush.

Rinse off the solution with clean water. Dry the grout completely to prevent the mildew from returning.


Wear gloves and a mask when cleaning mould to protect your health. When disturbed, mould emits spores that can be inhaled.
