Sweep the floor with a dust mop at least once a day. The dust mop removes soil and fine pieces of grit that can scratch and dull the maple surface. Sweep under rugs and furniture and get into the corners where dirt tends to accumulate.
Mix one part vinegar with two parts warm water. Alternatively, use a commercial maple or hardwood floor cleaner. Dampen the mop in the cleaner and wring it out until it's barely moist. Mop the entire floor with the cleaner, using it sparingly.
Dry the floor immediately after mopping, with a soft cloth. Standing water can break down the floor's finish. Water also causes the wood to swell, which results in permanent damage. Buff the floor dry with the cloth to bring out the natural shine in the wood.
