Weekly care for your polyurethane finished hardwood flooring should involve sweeping to remove larger dirt particles, followed by the use of a wood floor spray cleaner (we carry Bona’s brand of wood cleaners) and terry cloth dust mop. Avoid using a sponge mop and water solution as repeated use will raise the grain in the wood and damage your flooring. For deeper cleaning, we offer a clean and recoat service to renew the look of your hardwood floors. Polyurethane finished wood floors can be screened and recoated many times in their life without sanding away the wood surface. However, we do offer a wood floor Sand and Finish service when customers have large scratches needing repair.
