Chlorine bleach is a common household chemical. Used on everything from clothing to toilets to countertops, bleach effectively removes germs and bacteria from a variety of surfaces. When used to wash benches, bleach solutions sanitize the seating area, leaving them fresh and clean. However, bleach also contains a yellow dye that can leave unsightly stains behind. Fortunately, a few everyday items will remove the yellow and successfully restore bleached benches.
Combine 1 tbsp. liquid dishwashing soap and 2 cups of warm water. Stir the solution vigorously until suds begin to form. Dip a sponge into the soapy water. Squeeze the sponge firmly to remove any excess fluid. Use the moist material to wash the stained areas thoroughly. Rinse the soap away with cool water.
Pour ¼ cup distilled white vinegar into a small bowl. Add 1 cup of warm water and stir until the two are well blended. Use a white cloth to dab the vinegar solution on to the stained area. Rub gently, working the vinegar into the surface of the stain. Wipe the solution away with a wet cloth. Pat with a paper towel to dry. If any discoloration remains, repeat the treatment or try a different remedy.
Dunk the end of a cotton swab into a bottle of 3 percent hydrogen peroxide. Wipe the wet material over any yellow spots. Let the solution sit for 10 minutes. Rinse the peroxide away by wiping the area with a damp sponge.
Pour ¼ cup baking soda into a shallow dish. Gradually add water to make a grainy paste. Spread the mixture over any remaining stains. Scrub baking soda lightly with an old toothbrush, working from the outside edges of the stain towards the center. Rinse the paste away with clear water. Buff the surface dry with a clean towel.
Spread a 1 tsp. of non-gel toothpaste over stubborn stains. Rub the toothpaste gently into the stain with a damp sponge. Let the toothpaste dry and then wipe the residue away with a damp cloth. If any yellow areas remain, repeat the stain removal procedure.
