WD-40 has been known as a lubricating and penetrating product for decades, and while it may seem simple to use, it began as rocket science. Originally designed by the Rocket Chemical Company in 1953 as a degreaser and solvent for the aerospace industry, five years later it was introduced to the public. Sold from car trunks by the company's seven employees, the use of WD-40 quickly became widespread; the company changed its name to match its only product, and today boasts of over 2,000 uses for a penetrating oil that became a household name. Among its 2,000 uses are several that will remove stains from your hardwood floor.
Sweep the stained area to remove all dirt and debris.
Spray a small amount of WD-40 onto a lint-free cloth; two to four seconds of spray will be an ample amount to treat most stains such as crayon, adhesives, ink and permanent marker, nail polish and black scuff marks.
Rub the stain vigorously with the dampened cloth, using a circular motion and turning the cloth to a clean area as the stain is removed.
Repeat the process if portions of the stain are still visible.
Clean the treated area with a hardwood floor cleaner that has been recommended by the manufacturer.
- Always use adequate ventilation, hand and eye protection when using WD-40. Always clean up WD-40 residue immediately after use to avoid the risk of slipping.
- WD-40 is flammable and should not be used near open flames such as a fireplace or pilot light.
