Q. How do I clean water marks off a concrete floor? I recently put concrete floors in my home with a stain and a polished finish. Any time water drips on them it leaves a permanent water mark.
A. Cleaning water marks off polished concrete floors can be difficult. Sometimes deposits in the water will etch the surface of the concrete leaving a dull appearance where the water dripped on the floor.
You can try this Neutral PH cleaner from Black Diamond. If that doesn't work you may have to rebuff or polish those etched areas again to restore the polished look.
