In 1953, the Rocket Chemical Company made 39 unsuccessful attempts at creating a water displacing spray. On the 40th attempt, the company successfully concocted a formula that repels water and prevents rust. Known as WD-40, the product quickly became a common sight in many households. There are literally thousands of uses for this inexpensive spray, including polishing wood, silver, brass, metal and gold. You also can polish away counter top scratches with WD-40.
Remove the red plastic tube attached to the WD-40 can and insert it into the spray nozzle.
Hold a clean, microfiber cloth out flat in one hand. Hold the can of WD-40 with the other and position the red tube 1 to 2 inches above the cloth.
Press the trigger of the WD-40 can with your index finger to dampen the cloth with the spray.
Rub the wood, silver, gold, brass or metal with the damp cloth. Polish in a circular motion for several seconds.
Continue applying the WD-40 to the cloth and polishing the item. Let the item dry.
