Cleaning hardwood flooring

Use a well-wrung-out cloth, sponge, or mop, with a few drops of dish-washing liquid or all-purpose cleanser and warm water. Sweep or vacuum frequently to remove grit. Do not wet mop, since water will damage the finish. Do not apply wax to a floor coated with urethane or polyurethane. Do not apply sprays or oils meant for wood furniture; they will make floors slippery. For tough stains, scrub gently with a nylon pad dampened with dishwashing liquid.
