Spills, Stains, Chips and Scratches?
Most drinks stains will weather out naturally or can be cleaned down with soapy water and a hard brush. Other damage or stains can be removed quite simply using ordinary sandpaper. The grade of sandpaper depends on the degree of damage. Serious damage, start with course and move up to fine. Light damage, fine grade is all you will need. Stains usually disappear with a light sanding.
