Clean the table to remove any dust or dirt that could potentially cause further damage during the course of the repair.
Apply the jewelers rouge to the polishing pad, a small amount will work. If you cannot find jewelers rouge, non-gel, whitening toothpaste can serve as a substitute.
Put on your particle mask and goggles, apply the pad to the electric buffer, and run the buffer over the scratch using light to moderate pressure. If you do not have an electric buffer you can go over the scratch by hand with the polishing pad.
Leave your mask and goggles on, put on the plastic gloves and mix the 2 cups of warm water and ½ oz. of ammonia together in the spray bottle.
Spray the ammonia solution onto the buffed area, while still wearing your personal protective equipment, and carefully wipe it with a paper towel.
Examine the area. If the scratch is still visible, steps two through five can be repeated up to two more times. If the process is still not effective consult with a professional.
