    Hi, I installed slate tiles on my kitchen wall ~10 days. I did my best to clean the tiles of excess grout while the wall was still wet, but I didn't do a good job.

    Can anyone here offer real-world experience on getting grout off slate tile surface? I understand that some grout on stone tile surfaces is acceptable (adds to the 'rustic look of the wall), however I would like to minimize this.

    Sorry for posting this on 'all things gay', but I wasn't sure where to post this.

    A metal scouring pad may work.
    I've applied this on my floor about 1.5 years ago...it worked for me.

    something like this

    Thank you... I have used scouring pads and strong bristle brushes with success, however it takes time and patience... time I have, patience I don't LOL. I'll try the metal ones some spare tiles (my fear is that they will damage the stone surface).

    thanks again!

    You're welcome

    I have 2 things to tell you
    1. If you think it may damage your stone surface, have you tried on a small area?...if it doesn't damage then you can move on to whole space.
    2. Have patience ;)...this is the cheap and best way I could think of...if you can look in YouTube or Google, you may find some interesting tips.

    I have some spare tiles I can test it on. The best success I've had so far is with warm water, white vinegar or grout remover coupled with a good scouring pad. cheap! but lots of sweat equity.

    The tiles look great and the grout doesn't detract from their finish. I'd leave them as they are. Grout is hard enough to remove from smooth highly glazed tiles, so I think you would struggle to remove it without damaging your tiles.

    Perhaps a soft copper bristle brush?

    It is pretty much impossible. Acid grout cleaner and a rental floor scrubber with steel brushes and lots of time.

    Clean backsplash with acetone or paint thinner. If push comes to shove and you can't remove the grout from the crags, you can stain it with a wood stain mixed with paint thinner. Had that issue several times in different jobs before and it worked. Some tiles are just a pain in the ass to clean.

    I tiled my kitchen backsplash last year. The one tip the guy at the tile store forgot to mention is that slate tile should be sealed ahead of grouting. Indeed I ended up with grout haze, and none of the chemical solutions mentioned in this thread or anywhere online did a thing to remove the haze. Fortunately I only used slate for the mosaic tile inlay above the range. I tore it out and started over.

    Thank you for offering nothing... I asked for real-world experience.

    Sealing BEFORE grout was an invaluable tip. Unfortunately it was after my FIRST effort, but fortunately on a much smaller area.

    This worked for me . . . but the hand and wrist and elbow and shoulder cramps after I got the entire area cleared of the errant grout. (And for a guy who prices himself on his skills on his knees, believe me when I tell you that doing that floor tile by 1 1/2 by 1 1/2 tile rendered my knees out of commission for days! icon_cry.gif )

    That looks amazing! Unfortunately I can't rip out my tiles... I did the entire wall.

    I did apply sealant before grouting, but i still ended up with grout-haze.

    Hi, yes I have bristles and yes vinegar DOES work!! Cheap too :-)

    The woodstain mixed with paint thinner is something i'll try as well.

    I am slowly working through my tiles, here is a picture of the wall (It is a selfie shot... I am pulling out the top row of tiles to accommodate for the microwave bracket). This picture was taken earlier this week.

    Mr Clean magic eraser and marinate the grout in Lysol toilet gel.
