    Is this cleanable? The tile feels clean but is discolored. Any ideas?

    Thanks[​IMG][​IMG][​IMG]

    Have the dog pee on the rest of it so its all stained evenly.
    OR
    I would try a peroxide. What kind of tile is it? You could try an acid if there is no risk to damaging the tile, or you are feeling brave... ​

    It is polished granite. I think the pee got in the grout lines and seaped into the stone .

    I think I'd try a higher PH peroxide. Something like Viper Peroxi Blast. See how that does to remove the stain. I've had some good luck with that in restrooms with older epoxy floors. If it was ceramic tile I'd say go for a lower PH product like Peroxi Bright, but an acid on granite I believe would etch.

    I think so as well. I will test a spot . If it does not come clean then I will pass on the job.

    You'll probably need a poultice. Also acid is fine on granite

    I thought acid wasn't a good idea on granite because of the minerals in it. I mean, you can but you'd have to be careful and re polish when you're done. Does it not react with granite then?

    Granite is not acid sensitive.

    Well I need to reread some of my literature, I could have sworn granite was included with acid sensitive materials.

    AZ is the EF Hutton of stonework. When he talks, I don't just listen, I take notes.

    Marble, trav, limestone, onyx. Acid sensitive.

    Some darker granites are coming dyed these days, the dye can be removed by acid. But there are ways to fix it without refinishing.

    Calcite is the issue. Acid reacts with calcite. Limestone, travertine, marble, etc. have high concentrations of calcite and granite has very little to none.
