Do you have PermaWear finish on your hardwood floor? Medallion Hardwood Floors feature this special type of finish that uses aluminum oxide for an extremely tough, low gloss surface that lets the wood's natural beauty shine. It keeps looking like new much longer than typical factory applied polyurethane finishes. Premium Bona hardwood floor cleaner is especially well-suited for this type of flooring. It's safe and effective, and will lift the dirt without damaging the PermaWear finish.
