How to remove mold & mildew stains in the bathroom

It is not uncommon for mould and mildew to form in bathrooms. Excess moisture and humidity are present in bathrooms, which are the conditions required for mould and mildew growth. Bathroom mould and mildew is unsightly and makes the bathroom look unclean. Remove mildew and mould from the bathroom using common household products.

Vacuum or dry scrub moulded areas. This will remove any loose mould from the surface.

Place a few squirts of non-ammonia dish soap into a bucket. Fill the bucket with warm water.

Scrub the mould and mildew-stained areas of the bathroom with the soapy water and a scrub brush. Rinse out the brush often in the bucket of water. Change the bucket of soapy water if the mould and mildew is heavy and is soiling the water quickly.

Rinse the surfaces with a rag and plain water. Allow the surfaces to air dry.

Discard the bucket of soapy water. Rinse out the bucket well.

Fill the bucket with 1 gallon of warm water. Add ¼ cup chlorine bleach.

Dip a rag into the bucket and wring it out. Wipe down the affected areas of the bathroom with the rag and bleach water. Rinse and wring out the rag frequently.

Allow the bleach mixture to sit on the moulded areas of the bathroom for about 20 minutes. Wipe down the areas a second time with the rag and bleach water. Wait another 20 minutes.

Rinse the affected areas with a rag and plain water. Wipe over the area with a dry rag to remove any excess moisture.


Keep your bathroom well-ventilated to reduce the amount of moisture and humidity in the air. An old toothbrush works well for removing mould and mildew from grout, corners and other tough-to-reach places in the bathroom. Wipe down the affected surfaces with a borate-based detergent and water. This will help to keep the mould and mildew from growing back. Look for borate, borax or boric acid listed in the ingredients of the detergent. If your plastic shower curtain has mould or mildew, soak it in the bathtub or washer with about ¼ cup chlorine bleach to every gallon of water.


Wear rubber gloves and work in a well-ventilated area when removing mould and using chlorine bleach. Wear old clothing that covers your arms and legs to protect your skin from the bleach. Wear a face mask and protective eye wear when removing large amounts of mould. Never mix bleach and ammonia or products containing these ingredients. The results could be fatal.
