Q: My dark 2 year old hardwood floor has developed a light patch in front of the couch. I have tried gently washing it. I usually clean with a [popular brand] floor mop. Do you have a suggestions for me?
A: My guess? According to the makers of these products one of the ingredients is wax. Wax should not be used on polyurethane coated floors. When wax is used as a finish and a small spill occurs, for example water, a white spot will appear. I would suggest you look into getting some appropriate cleaner which leaves no residue of any kind but does remove such contaminants. Poloplaz, Basic Coatings and Bona Kemi are, amongst others, companies which make such products.by
