Our flooring guy gave us a "recipe" for floor cleaner (we have refinished pine floors- no stain just 4 coats of urethane)
1 gallon Distilled Water
1 quart of 99% Alcohol
1 TBSP of Dawn soap (NOT antibacterial)
1 or 2 drops of food coloring (to tell what it is) Haven't used it yet, but I trust him that it will work- 35 years dealing with floor refinishing.
I am assuming that this is to be used only on protected floors though.
