I just bought a house and I pulled up the carpet and found a hidden treasure. I have parkay floors in all of the bedrooms and the hallway. The only problem is the people that lived there before me did not take care of the house and I have serious black mold all over the parkay floors. I started sand them and aftr 12 hours I don’t even half half of one bedrrom done! Is there a simpler way to get the mold and stains off the floor? I really want to keep the floors.
