Here are some rules to abide by when cleaning your hardwood floors:
Polyurethaned floors should never be waxed and require cleaners that won’t leave a film or residue.
To remove occasional scuffs or heel marks, spray some cleaner on a cloth and lightly rub the stained area. Sticky spots can be cleaned with a damp towel or sponge.
Never use ammonia cleaners or oil soaps on a wood floor, as they will dull the finish and performance of your floor. Also, ammonia cleaners may affect the ability to recoat your floor later.
Wood floors expand when wet or in high humidity. Therefore, never wet mop or use excessive water to clean your floor. Large amounts of water can cause the wood to swell and may cause your floor to rise up.
Since hardwood is a natural product, it will expand and contract due to moisture level changes. Keeping water exposure to a minimum and cleaning up spills as soon as they happen is key in having beautiful, long lasting wood floors.
