My neighbor, the wood floor installer, helped us sand our real wood white oak floors when we installed them 5 years ago. After putting on several coats of poly stuff I asked him what to use to clean. He said to use vinegar and water, NOTHING ELSE.... I use one of those micro duster floor mop. The vinegar/water mix really cleans.. my floors look brand new..... use probably 1/2 and 1/2 or less vinegar if you want.... I also use the same mix for washing windows and mirrors. Use a squeegee - no streaks.....
