If your floor has been shellacked or lacquered, you’ll have to strip and wax it yearly. You can use denatured alcohol and lacquer thinner to test your floor finish. Test a small area of the floor you normally cover with furniture or a rug. Apply 2-3 drops of the alcohol. After a few seconds, touch the spot with an old cloth. If it feels soft, it’s shellac. If the alcohol doesn’t soften the finish, apply 2-3 drops of lacquer thinner to a nearby spot. If it softens to the touch, the finish is lacquer. If it feels tacky, it’s likely water-based.

Use smooth strokes. Start at the interior corner and work outward toward a doorway. This motion will keep you from stepping on your wet floors. Wipe up excess liquid if you see standing water. It can cause damage and buckling in your floors. Use a clean dry rag or towel. Make sure the surface is completely dry. Never mop floors that have been waxed. Clean them by vacuuming and sweeping.

You could also rent a buffing machine if you prefer. Move the machine in the direction of the wood grain. [6] X Research source
If no damage appears, you can polish the entire floor. If you see discoloration, seek advice from a professional contractor.
If your floor has been waxed, apply 2-3 thin layers of polish instead of one thick layer. Wait for each coat to dry completely (about 24 hours) before applying the next one. [8] X Research source
Block off the area with painter’s tape or a chair for at least 6 hours. If you have companion animals, keep them away from the polished area for at least 24 hours. You could also fit them with “doggie socks” after 6 hours.
