the PH is too high for stain resist nylon, Bill.
neutralizing doesn't help either, cause the damage is done to the strain resist properties while the juice is dwelling.
Use PB for the "rough" jobs and have another quality pre-spray with a PH of 10 or below for residential stain resist nylons
Ultrpac is hard to beat for that.
yea, it's expensive, but IMO, it's the "gold standard" of stain resist approved pre-sprays
side note; if a res nylon is TRASHED and in need of restoration cleaning, then by all means hit it with a sledgehammer and forget about the the PH restriction
..L.T.A.
Larry, I agree with almost everything.
Not the Ultrapack though.
I used to use it exclusively for years and then stopped. I never looked back.
Ultrapack is an over kill. And it needs a very heavy rinsing (not just water) and even acid rinses sometime are not enough.
There are much better and more easily rinsed pre-sprays if you need.
It does work though on the really bad ones.
Cough! Cough!
