If they are painted or dyed which may be why there is color bleed off in the grout .
You would want to use a stripper that wont take out of degrade the color.
Maybe a light dilution of a wax stripper that doesn't contain butyl or has a low amount.
I think a product called ultra-strip may work if you can get it.-test first.
Maybe a high alkaline cleaner would get it off.

Hey Stuart, what do you think would be a safe product to remove the rest of the film on these tiles?

There were a couple of spots where the grout appeared to have some brown spots. Looked like traffic stains at first glance to me.

Thanks buddy!

Looks like a terracotta tile painted or stained and coated prior to installation.
The grout lines look clean with no sign of  a coating.
Hey is that (close up pic) a little brown color in the grout line?
Just guessing here-
I would call those etch like looking things etches anyway. Looks like they etched the coating and probably best to remove them so they don't show up in the new coating. I think we would clean off the residue lightly and recoat with something like TK6(Richard James) or dress up from sparks.

Hello everybody! I looked at this floor today that appears to be clay or something similar (not sure). Home owner said it was hand made in Italy. Carpet cleaning company came in and partially stripped off a semigloss sealer or light wax that was on the stone (see pics). No damage to stone. Just marks where topical sealant was removed and crusty white build up in corners and along edges. Should I strip and apply another wax type coating? Home owner wants it to look like it did which as I said looked like a semigloss finish. The ring marks are where company must have left machine on for a longer period of time time. They are not etches, but rather where finish has been removed.


Thanks!
