I am trying F90 at the moment, before I ordered I asked chemspec, it is not a prespray, it is a rinse agent. You adjust the dilution rates, so it can be woolsafe if needed, and it dries to a powder, but its not a true encap. I'm trying it because I did want some cleaning power in the rinse agent.
I use enzall for restaurants etc, greasy food deposits etc, never had any reason to change from using it.
