JUST LAID A NEW LIMESTONE FLOORING AND AFTER THE GROUT WAS INSERTED, I NOTICED A CHALKY HAZE OVER THE TILES THAT WILL NOT COME UP. I'VE TRIED SCUBBING, BUFFING ETC. WITH NO RESULTS. PLEASE HELP!!!
Muriatic or a hydrochloric acid should remove the haze on the tiles.Muriatic acid is most common and you can get it at the hardware or home store.Follow directions carefully.
