5 Gallon Pail. Mr. Floor’s Wood Floor Cleaner is specially formulated to properly clean wood floors. Since it is non-acidic, it will not remove your finish or dull the floor’s surface. It is perfectly balanced to clean without harming; no more smelly, toxic odors. It is environmentally safe and fully biodegradable. One of its biggest advantages is that it will not leave a residue behind. A residual build-up can develop into a thick film that traps dust & dirt causing excessive wear. The more you use those “other” cleaners, the more harm you cause your floors.
