Just got through with the hard part (removing old grout) and now need a little advice.

I need to clean the old tile and the suggestion I got was tri-sodium phosphate to get rid of water and soap
stains and 50:50 clorox solution for mildew. Also have rust stains, and that usually is cleaned with mild acids.
I know to keep them all as totally separate treatments with long rinses to avoid gassing myself - even with all
the fans I have going.

Any other suggestions or is what I am doing the easiest way to clean the tile with all its different stains?
