Yes, but with caution. A floor grinder is intended to level and polish concrete, so it is a very powerful tool. To remove paint, the floor grinder should be set to 35 square feet per minute or less to minimize the pressure without the use of pocket weights. You might need to go over the surface two times to get any paint that has sunk into the concrete’s pores.

Yes, a magic eraser can remove candle wax. You can use it to remove all the candle wax from start to finish. Another option is to remove all large clumps with a dull knife and then pull out your magic eraser to finish the job.

If you try this method, test a small, hidden spot first and proceed cautiously.

Baking soda is an excellent choice for a natural dog urine neutralizer. You can sprinkle it on a stain, leave it overnight, and then vacuum it in the morning to help rid your hardwoods of the dog urine smell.

Before starting on a full refinishing project, determine if your floors need to be completely sanded down to the bare wood or if the damage is shallow and mostly cosmetic. Deep scratches and gouges will require you to rough sand using a drum sander or belt sander, but small surface scratches or floors that have only lost their luster don’t need a complete overhaul. Instead, you can skip the rough sanding step and sand-screen the old finish with a buffer, removing only the top layer of polyurethane.
