How to remove grout sealer from tile?

Former owner used grout sealer over entire counter tops. I've tried chemicals, goo gone, stone cleaner, and fingernails. It just gets gooey so you cannot use a sander. Scraping these tiny tiles one by one is not an option. Cannot afford new countertops.

    Have you tried paint remover or fingernail polish remover with a small smooth rag.?

    Be sure to try the above on a non promenant back tile first.

    Sounds like this sealer is a silicone based product or not sealer at all but clear silicone smeared. Home depot or other stores have a remover for silicone. It actually sort of melts and you wipe it off with the silicone many times with a rag or paper towel. You can not afford new tiles so you have to work at it. I thought at first getting or renting a grout removal tool would be the answer. But although it will cut the grout down for a easy re grout, The silicone is a dastardly product to get rid of, and nothing will stick to it. Oh by the way a true sealer goes into the grout and is done every year to protect from stains , it is washable and will finally wash out, hence the treatment each year. No these people rubbed silicone over the tiles for some reason got bad advice. To find out about silicone remover do a google search and be prepared to follow instructions. Spray, let set, wipe and wipe and wipe.
    Oh by the way if you decided to use a vibrating tool and diamond cutter to dig out the top half of the grout after the cleaning, the new grout can have treatment in it for no need tore treat it (seal).
    Good luck

    I'd take this photo to Home Depot and ask which chemical remover they most recommend. Good luck!

    Suggest you get address of the grout sealer company and write to them for a solution.

      Done in 1988... Former owner moved out of town 5 yrs ago. So probably not an option. But thanks.

    Then check out 'other' grout companies at hardware store or Do-it-yourself store and write them for way to remove sealer from tile. They should have a way to remove their sealer from tile. It pays to write....I was missing a dominoe from my set and wrote company and they sent me the dominoe I needed. I had two dominoes exactly alike and was missing one. Remember "the squeaky wheel" gets things done. ha

    Have you tried ammonia? Years ago, I used an acrylic grout paint on my mother's glazed tile, and it cleaned up very nicely from her glazed tile, so I used it haphazardly on my unglazed til, which was a huge mistake! The grout paint permeated the tile and proved EXTREMELY difficult to remove. I read that household ammonia would do the trick, and it did work for me, albeit with LOTS of elbow grease, so I left several areas that I still need to work on. I'll fiinish the job after we move, in the not too distant future (meanwhile, it continues to be an ugly eyesore that I have to explain to new visitors, lol). I haven't finished the job because it took so much time, then we moved into the house, and we have pets we don't want compromised by breathing in cleaner and ammonia fumes! We share a similar problem, so my heart goes out to you!
