1) Clean your floor at least once a week. You can do this with the use of a dust mop or a vacuum. Vacuuming protects your floor's finish by sucking the fine dust underfoot. Such dust is capable of sanding wooden floors.
2) Protect your floor from rain and from direct sunlight. Both can ruin your floor finish. Water can cause unwanted stains. Close your windows closed during hot months and keep your ceiling from leaking during rainy season.
3) Protect your floor from scratches. Your floor can be scratched by your pets' nails and the base of your appliances and furniture. Avoid rolling heavy appliances and furniture on the floor. If it's impossible, use plywood hardboard to lift them.
4) Wipe spills right away. As much as possible, keep body lotions and hairsprays from spilling on your hardwood floor. They can destroy your floor's finish. Wipe them off with a damp rug.
5) Cover high traffic areas with runners and rugs. High traffic floor areas get worn out easily. Rugs can help preserve their appearance. Make sure that your rugs have anti-slip backings. However, avoid vinyl or rubber backing because they trap humidity. Accumulated humidity can damage your floor’s finish in the form of stains.
