How do I keep my new wood door clean?

Lightly dampen a microfibre cloth and gently wipe the surface area you wish to clean then follow with a dry microfibre cloth to dry off the surface. Do not spray any products with chemicals on or near the finished surface as it may damage your finish. You cannot spray the door with water or a high-pressure washer as it will penetrate the polyurethane and cause the wood to swell.
