I just finished a shower stall project (this is before I grouted) :
My question is this, I got grout all over the tiles, and while most of it scrubbed off, some almost looks like it stained the tile. It's a very thin coating that I can feel with a fingernail in some spots and in others it's down in the texture of the tile.. Is there a good way to remove this excess grout that wont damage the tiles?
Is that grout or thinset? Either way the longer it stays on the more difficult it will be to remove. A scouring pad and water would be your best bet. Acid washes are available, although they can stain your tile. The tile or stone that you have used appears to have a matte finsh, which of course will make this job more difficult. In the future clean the tiles before the thinset dries. In some cases a grout release should be applied to the surface (not the edges) before grouting. Check with the manufactor.
Thanks for the reply(s).
I got it all off using (major embarrassment here) a product that is made where I work! I diden't know that it would work on tile (we make it for cleaning masonry) so I wrote it off. It turns out that as long as there's limestone in the product it'll attack it.
