WATER SPILLS AND DAILY USE: Clean water spills up as they occur during regular use and protect from heat. Although General Finishes products are water resistant, they are not impervious to water. Surfaces will not be damaged by spilled water so long as it is cleaned up promptly. We recommend using coasters to protect your wood from standing water and pot holders to protect from heat.
CLEANING YOUR FINISH: Clean with a water-damp rag. Do not clean until the finish has cured completely (21 days).  If your surface requires deep cleaning due to grease or grime, add a speck of detergent or a bit of vinegar. Avoid using oil-soap or silcone-based daily cleaners such as Pledge, Endust or Murphy’s Oil.
Always avoid the use furniture polishes, dusting sprays or oil soaps as they may contaminate the finish for future recoating. Use a water dampened cloth for regular cleaning.
