Hey guys, I think I posted about this in here before, but I’ve got this unglazed porcelain that a customer mines used in several of their locations. No pics on this one but I run in the situations where the epoxy grout job was not done well and has absorbed into several areas of the tile and leave some areas kind of splotchy and shiny I usually clean the heck out of it, scrub the shit out of it, and it gets the dirt off the glaze and it kind of looks pretty decent. That’s one location. this other location picture posted here, I can’t use a spinner on it It’s on the fifth floor of a commercial building. I usually end up, scrubbing the hell out of it, scrub The grout put a lot of alkaline on it and pick it all up with a small auto scrubber lotta detailing and I usually looks pretty good but this last time I came in and it looks like somebody either put some acid super pee on it. Couple of drips looks like it cut right through whatever this grime was or maybe they put something else on it. I don’t know what happened to it, but it looks like a cut through this stuff, but I can’t find anything that will do this. Any ideas guys need your help?
