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.

Step 2
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.
Step 3
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.
Step 4
Repeat the process if portions of the stain are still visible.
Step 5
Clean the treated area with a hardwood floor cleaner that has been recommended by the manufacturer.
