How to Remove Brown Spots From White Sinks

Updated February 21, 2017

White sinks show stains easily and can be difficult to clean. You can purchase another colour sink or clean stains as soon as you notice them. This will prevent the stain from soaking into the white sink, where it will be tougher to remove. Brown spots on your sink could be caused by mould, rust, dye or other types of staining material. Clean using solutions and tools that will not harm your sink, whether it is porcelain or fibreglass.

Add just enough water to 1 tbsp of baking soda to make a thick paste.

Spread the paste over the brown stains, working it into the brown stains with a damp cloth. Work until the stains are gone.

Rinse the area completely.

Ventilate the bathroom to protect yourself from bleach fumes.

Soak a paper towel with undiluted bleach, if the brown stains are from mould or mildew.

Lay the paper towel over the brown stain and let it sit for 15 minutes.

Remove the cloth and rinse the area.

Mix 1 tbsp of ammonia with 1 gallon of water.

Dip a piece of superfine steel wool in the solution and scrub over the brown stain until it is gone.

Rinse the area with clear water.

Dip a scrubbing brush into white vinegar.

Scrub the surface of the sink to remove the brown stains. This is particularly effective if the stains are from rust or hard water marks.

Rinse the area with clear water.

Tip

Don't mix ammonia and bleach as they can cause a toxic gas.
