Rob I agree with you, I love the way your sf rinse 8ph rinses, how ever I don't agree that rinsing agent leaves residue crystals when it dries which needs to be vacuumed, not all my customers will vacuum, what happens then? It will re soil quicklyI personally run an alkaline (8.0 so barely alkaline) at 1/2 dilution. Works like a champ.
Residue that dries to a crystal is certainly better than residue that bonds directly to the carpet ... I get that customers won’t necessarily post vac but at that point it’s on them
