Bleach is a cleaner and germicide used for many household stain removal projects, including the removal of mold, mildew and dirt on bathtubs. If you have an older bathtub, you may be horrified to discover that the bleach that cleaned your old bathtub has left behind brown and yellow stains on the surface of your tub. Use simple supplies to remove the discoloration caused by the bleach. Then prevent bleach stains on your bathtub by using non-bleach cleaners or natural home remedies.
Place equal amounts of cream of tartar and hydrogen peroxide in a bowl. Mix the two ingredients to form a thick paste. Add more cream of tartar, if needed, to thicken the paste to the consistency of peanut butter.
Apply the peroxide paste to the bleach stains on your bathtub in a thick layer, using your sponge. Make sure to cover the entire stain. Allow the paste to remain on the bleach stains until it's completely dry. This may take a few hours.
Wet the sponge and wipe at the peroxide and cream of tartar paste on the bathtub. As you remove the paste, the bleach stains will be removed, as well. Rinse thoroughly with plain water.
Create another bleach-stain fighting paste to remove any stubborn remnants of bleach stain discoloration in your bathtub. Mix an oxygen laundry detergent with water to create a paste.
Scrub the laundry detergent paste into the bleach stain remnants with a clean sponge. Rinse with plain water to remove the detergent paste and bleach stain.
