We just installed new tiles in the bathroom. Unfortunately, while
applying the grout some made it on the surface of the porcelain
tiles. The grout on the tiles was left overnight which is resulting
in haziness and now needs to be removed. Tried a few things but the
grout on the tiles is very stubborn and is not coming off. Any
Tried Aqua Mix and am now trying Sulphamic acid. Anything else I
could try and are there any tricks when using these that would make it
easier to remove the grout without damaging the tiles? thanks.
