I had tried to clean my floor in the living area, usung a traditional mop, sponge mop using various floor cleaning liquids and neve got the floor to look how it should. I then bought a steam mop and that did not work either.
My daughter in law purchased the KOH starter kit and we did a spot clean in the kitchen. I immediately purchased the started kit and proceeded to clean all of the living area.
The photos attached are before and after from under the dining table. Amazing transformation.
