What type of tile?

I have porcelain tile. The way I removed extra grout from on the tiles was by first scraping off the mounds of grout (with a putty knife), then scrubbing the area with warm water and a nylon sponge scrubber. Finally, I rubbed the area with grout haze remover (mixed strongly in a spray bottle) then rinsed with clean water. I had HUGE globs of grouts on my tile and this process worked beautifully-but it is porcelain tile.

function first-- Any chance you could take pics and either post them, or send them to me, and I'll post them for you? I'd like to see just how much grout and how heavy, as well as the type of tile, as brickeyee asked.

Yes, I will try, but I'll probably have to ask my son to come over within the next few days and help me. It's porcelain tile with a textured surface, so even hard scrubbing leaves grout in some of the crevices.

nkkp, I have tried the haze remover full strength but it doesn't help. Perhaps I'm doing something wrong there.

bill vincent, I am still waiting for help to post pix. The grout is mostly on top of a liner and "overflowing" from many of the grout lines, if that makes sense. It's also in the crevices as I mentioned. I've been scrubbing with a plastic bristle brush (pretty strong bristles) but I'm worried that I'll scratch the tile and/or take the finish off the liner which looks like oil-rubbed bronze and seems not to actually be tile. It feels like something else. Someone (not on this board) suggested acid. What is your opinion? Many thanks.
