Acetone is an extremely harsh chemical often found in nail polish remover. While it may remove certain stains, acetone is extremely dangerous to use on wood floors.
Acetone is sometimes used in chemical products designed to strip wood and remove any existing stain from floors. Acetone in this form immediately begins to eat through the stain or paint on the floor.
Acetone shouldn't be used on hardwood floors, but you may want to use it in an inconspicuous area, such as a spot hidden under an area rug. Use a cotton swab to apply a small dab of acetone, then wipe it away with a cloth soaked in fresh water.
Acetone-based nail polish remover has the same effect on wood as full-strength acetone or paint stripper. Even a small amount or a few drops spilled on your floor can significantly damage and discolor wood floors.
