Comments on: Can I use sulfuric acid to clean some old varnish off tile? http://www.mosaicnovelties.com/can-i-use-sulfuric-acid-to-clean-some-old-varnish-off-tile.htm Welcome to Mosaic Novelties, everything to do with Mosaic Tiles, Slate and Mosaic Home Decor Tue, 21 Jun 2011 02:04:16 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Marcia F http://www.mosaicnovelties.com/can-i-use-sulfuric-acid-to-clean-some-old-varnish-off-tile.htm/comment-page-1#comment-1004 Marcia F Fri, 22 May 2009 21:37:59 +0000 http://www.mosaicnovelties.com/can-i-use-sulfuric-acid-to-clean-some-old-varnish-off-tile.htm#comment-1004 I would try to gently scrape the varnish up and then apply a laquer thinner to remove the rest. Then go to Home Depot or Lowes and get Frazzle to clean the tile and grout. It does a wonderful job when applied with a scrub brush and has no odor.

It will float on top, heat up, possibly boil, with spattering, and acid burns, and ER visits. That said, there are probably better and safer things with which to clean that floor. The film you speak of is probably mostly wax and grease. Try ammonia or strong detergent. DO NOT EVER add water to conc. sulfuric acid.

Wipe on-wipe off. Never, never use sulfuric acid to clean anything except the drain. Use fast drying lacquer thinner to remove varnish. Wipe on-wipe off.

DO NOT use hot

and NO it WILL NOT remove the varnish

varnish is basically plastic and as you may have noticed the sulfuric acid is in a plastic bottle and has not melted yet

sulfuric acid will destroy metal and will desolve you tile very slowly

thats why the spilled area looks so good you 'burnt off the top layer that was holding all the old dirt and waxes in its pores

be very careful when using that stuff it desolves pretty much anything that is not plastic or glass

as for that other comment about being dangerous when mixed with water that is only true in an enclosed space like a drain line

Go to a hardware store and look for a stripper. mineral spirits might work. ask someone at the store what could be used. also check the cans of varnish for what is recommended to clean up the stuff. Good luck do not use sulfuric acid. mixed with water is will splatter and give off a toxic gas.
