a brand new senior care center was built in my area and I have been trying to get my foot in the door well here is my chance. The general contractor called me and said he needed the kitchen tile cleaned, Im thinking easy job brand new right? nope!!! He was trying to save money and let his general laborer guys apply mop and glo to it. now its horrible! My question is how to you remove it in an efficient manner? I scrubbed a test area using a general degreaser and followed that up with the hydroforce 15" for a single pass alot came up but is there a trick? below I will post a photo of a new tile to show you the type. Its a non slip style. I was thinking even a black pad? IDK ????
