Step 1
Place burled wood furniture out of direct sunlight, and away from heat vents or registers. These can fade and dry the wood.
Step 2
Clean burled wood that is sealed with polyurethane by adding mild dish soap to warm water. Dip a clean, lint-free cloth into the solution and wring it out until it is damp. Wipe the surface of the burled wood, and then dry it with a second clean cloth.
Step 3
Renew the shine on unsealed burled wood by putting a few drops of linseed oil onto a clean, lint-free cloth, and rubbing it into the wood.
