I have tile cleaning down to a science( or so I thought) but it seems once the weather breaks here and it gets hotter, I start having issues with some of my tile jobs... the haze appears and I can not get it off... I cut my GM to 2 scoops/ 2gal , lowered my water temp, mix the GM with cool water, use an electric sprayer and never let the chemical dry .. I also rinse well.. following up with a damp mop. Some floors just don’t cooperate . I tried acid on this floor and it wouldn’t come clean... I rinsed 4 times ... any recs? Should I be using a neutral cleaner in my rinse?
