Removing grout from stone tiles
by

Is there any way to remove dried grout from stone tiles? When we tiled our bathroom using mosaic tiles, we were not quick enough in some areas to get the grout wiped off the tiles and now some areas do not look so great. We used sealer on the tiles before grouting thinking that would help with the stones. Any ideas?

I would start by using a 50/50 mixture of white vinegar and water to loosen the grout first. Leave the mixture on for awhile. It may not be enough to remove all of the grout but it will start to loosen it. Then try to find a grout cleaner and gently apply as not to get it on the tiles itself.

I have used this little tool on ceramic tiles and found it invaluable. It works like magic. I believe they sell it on Amazon. http://www.vitrex.co.uk/details.php?sc=19&id=149

Go to Lowe's or Home Depot, they sell a product where the mastic and grout is that is basically and acid. Depending on how heavy the grout is on your tile you dilute the acid. Sponge it on your tile (not the grout lines) and wait a few minutes to scrape the grout off then go back over the area with a baking soda mixture (to stop the acid from working) then again with clean water.

if the cleaners don't take all of the grout off, grab your handy-dandy dremel tool - be sure to do it outside, wear safety glasses, and start with the softest grinder head you have.

I've used either a chisel or a razor knife to scrape off small blobs of dried grout.

Muriatic acid, if it is just a little bit your trying to remove buy The Works toilet bowel cleaner. It also has Muriatic acid in it, wear gloves use in a well ventilated area. I use a scraper and scrape it off.
