How to Clean Sulfuric Acid Stains

Sulfuric acid is a non-flammable solution found in batteries and is an ingredient in certain dyes, plastics, rubber, glue, film and other products. The acid can stain bathtubs, countertops and other hard surfaces. The stain is brown in color. Sulfuric acid gives off fumes--and even the fumes can stain surfaces. Regular household cleaners can't remove sulfuric acid stains completely. To clean sulfuric acid stains, you need hydrogen peroxide to break the stain up.

Step 1

Put on a pair of rubber gloves to protect your hands.

Step 2

Pour 1 cup of hydrogen peroxide in a small bowl or plastic container.

Step 3

Dip a clean rag or shop towel into the bowl of hydrogen peroxide.

Step 4

Remove the rag or shop towel and wring out excess solution.

Step 5

Wipe the sulfuric acid stain with the hydrogen peroxide-soaked rag or shop towel. If the stain is large or stubborn, put the wet rag or shop towel on the stain and let it sit for two minutes. Scrub the stain gently with a scrub brush and then wipe the stain with the rag or shop towel.

Step 6

Wipe the surface with a paper towel to remove any residue.
