How do you remove stains from hardwood floors? Hydrogen peroxide is suitable for removing dark stains and lingering smells on hardwood floors. Soak a piece of cloth in hydrogen peroxide and place over the stain overnight or at least 8 hours during the day. No one said removing wood stains was an easy task, sigh. Repeat for longer hours if the stain is resistant.
