Save your $$$
Absolutely did nothing, bought this to remove grout, used half the bottle and did NOTHING!!! Went to Walmart and bought a $12 can of stripper and worked within minutes (also works with floor leveling and concrete) so save yourself $40 and aggravation! And the real kicker is you can't return it because Amazon can't  receive items with flammable liquid, but they can ship it out?
