Most of the brand name Hard Wood Floor Cleaner machines will clean sealed hardwood floors along with a range of other hard floor surfaces. One product which is specifically made for cleaning hard wood floors is the Bona Kemi Hardwood Bare Floor Wet Surface Mop BK 710013348 with solution Cartridge and microfiber Pad. This product will not damage your hard wood flooring as some other products may by over wetting the floor or by leaving oily residues. If the wrong chemicals are used or the hardwood floor is damaged by wet mopping it will be required to be re-surfaced and that can be avoided with this product, which can be safely used on all non-waxed polyurethane coated hardwood floor surfaces. All you need to do is to spray, clean and then enjoy the natural luster of your hardwood floor. Using microfiber technology and a no residue cleaner, this represents a mild yet thorough cleaning action that will deal with stains such as red wine, mustard and sauces whilst preserving the texture of your hardwood floor. Care must be taken with hardwood floor surfaces not to use ammonia cleaners or oil soaps, and cleaners must be ph neutral. If the wrong products are used, there can be a buildup of oil and residues so that there will be a need to strip and reseal the hardwood flooring instead of a maintenance resealing.
Basically, most Hard Wood Floor Cleaner machines are suitable for hardwood floors provided there is a polyurethane surface which is not damaged, in which case wet mopping is appropriate.
If you decide to steam clean a hard wood floor, then a decision has to be made between a standard steam cleaner and a vapor steam cleaner. The standard steam cleaner allows more moisture to come into contact with the surface, but it is generally cooler than the vapor steam mop, about 220 deg compared with 300 deg. It may be preferable to use a vapor steam mop to avoid putting excess moisture onto the hardwood surface, and the higher temperature will not harm the hardwood surface. Problems are not so much with the hardwood flooring itself but most hardwood floors are protected with a polyurethane coating which will allow moisture into the wood if the coating is itself damaged. Bona is regarded as the worldwide authority in the area of hard wood floor cleaner machines and there are many blogs with discussion about the best ways to manage and keep clean your hardwood floor.
