Combine an equal amount of cream of tartar and hydrogen peroxide in a bowl if the stain appears brown or black. Minerals such as manganese build up on the shower floor and cause an odd discoloration. Allow the paste to sit for 10 to 15 minutes and then rinse the area with clean water.
Create a paste that consists of an equal amount of white vinegar and baking soda for other brown or discolored stains. Hard water and soap scum are two of the most common culprit of brown stains. Apply the paste over the stain and let it sit for up to 30 minutes. Rinse the area with clean water.
Mix 1/4 cup of a powdered dishwasher detergent with enough water to create a paste if the brown stain remains. Stir the mixture with a nonmetal utensil to prevent a reaction from occurring and apply it directly over the brown stain. Scrub on the stain with a toothbrush and allow it to remain for 20 minutes. Rinse the area with clean water.
