And speaking of which, the best way to clean wooden floors is to use only water and the best sponge mop. The hardwood surfaces are already coated with a protective layer, so none can penetrate the inside. You only need water on your sponge mops to dissolve the liquids and collect dirt more effortlessly. Use warm water if you’re working with stubborn stains, especially greases. And occasionally, it’s possible to use chemicals to clean and recoat the wooden surfaces with a new protective layer.
