Having a hard time getting a good clean on these travertine floors. Pictured is an acid spill that cleaned it beautifully and caused minor etching. Thinking of a nuclear option with some phosporic acid, then a nylo grit brush afterwards to buff out the etching. Yes, I have been doing this for 25 years and I know you don't use acid on m/l/t, BUT the alkaline's are not doing it and I do not want to cover it up with grout...too slow. Thoughts.
