How to Clean a Discolored Shower

Updated February 21, 2017

A discoloured shower and bathtub with stains caused by mildew, soap scum and hard-water deposits detracts from the overall appearance of a bathroom. Once these things build up in your shower or bathtub they can prove to be quite difficult to remove using simple cleaning methods. There are measures you can take that can help you restore your discoloured shower or bathtub to its original colour.

Mix together a solution of 1/2 cup vinegar, 1/4 cup baking soda, 1 gallon hot water and 1 cup ammonia.

Put on your rubber gloves and apply this solution to the walls of your shower with a sponge. Ensure there is proper ventilation in the area when using this solution. Open a window or put a fan in the doorway.

Scrub the solution onto the walls with a plastic-bristled brush to loosen the grime and deposits.

Rinse the solution from the shower with clean, hot water. The grime and deposits should flow off the wall, down the drain and out of your shower.

Wipe the entire area dry with a clean rag. Repeat the process for areas that were not cleaned 100 per cent the first time.


Never mix ammonia and bleach. This combination releases deadly chlorine gas, which can severely injure you or cause death.
