One good way to remove soap scum is to clean it with a solution made of borax, detergent and water. Create the mixture, place it on the problem area, let it sit, then rinse it off. You need a soft-bristle brush, a bowl, water and a cloth for this process.Continue Reading
Combine 1 cup of borax, 2 tablespoons of dishwashing liquid and 1 to 2 cups of water, which is just enough water to form a paste. The mixture should have a consistency that's similar to pancake batter.
Use a soft-bristle brush to apply the paste to the area containing the soap scum.
Let the paste sit on the affected area for 15 minutes. Do not allow the paste to dry, as this can make it difficult to remove.
Use the soft-bristle brush to scrub the paste into the affected area until the soap scum is gone.
Use hot water to thoroughly rinse the paste and loosened soap scum off the surface.
Use a clean cloth to wipe the affected area dry and to remove any remaining soap scum or grime.
