For cleaning before repair

I honestly have no problems using acids or bases to clean my floor. I do not care how toxic a chemical is either. All I want is something that WORKS. Since, I have had major problems finding anything on the acid side of the pH scale (everyone seems to be scared of acids for some reason) I decided to test this basic one. My kitchen floor is some kind of natural stone tiles with pits, grooves and other places for dirt to get stuck. I hate it. Never get natural stone tiles. I tried many products on it recently in an effort to really get it clean. It seems that the cheaper I go the better they are at cleaning. This expensive product was the bottom of the list with regard to efficacy. I used it at the top recommended strength and for the time they recommend, diluted in hot water. I found I was way better off using a cup (275ml) of 3% peroxide mixed with 2 liters of hot water, and a gentle squirt of dish soap (maybe 5ml). Even leaving that for the 5mins to directly compare this current product the peroxide was by far the best results I have seen to date. Although I am still on the search for something stronger, preferably something acidic.
