Consider your floor's finish before trying to remove a mark. If the stain is on the surface, your floor probably has a hard finish, such as urethane. If the stain has penetrated through to the wood, the floor probably has a soft oiled finish -- common in older homes whose floors have not been refinished and resealed.Wipe surface stains from a hard finish with a soft, clean cloth. If the area is still dark, apply bleach or vinegar and allow it to soak into the wood for about an hour. 2  Rinse with a damp cloth. 3  Heel marks: Use fine steel wool to rub in floor wax. 4  Oil-base stains: Rub the area with a soft cloth and dishwashing detergent to break down the grease.
