In kitchen. I tried paint thinner and it did remove some but not all. can someone recommend something better? Would clr do or lime away? Or are they too caustic?
I have no idea what “cir” is, but lime away will not remove grease. Mineral spirits (paint thinner) should remove grease on the surface of a non-porous material, but if the grease has soaked into the flooring, I doubt that anything other than replacement will do the trick. Can you give a description of your problem?
