In almost all cleanign situations, a light mist of water used with your microfiber will get the job done. The hardwood and hardfloor cleaning fluid is not a necessity, but is definitely an option to release spots like dried soft drink circles and eliminate oily stains and streaks on the floor. The light mist of the hard floor cleaning fluid should be used on linoleum, stone, and tile, while the hardwood solution should solely be used on wood surfaces.
