Do you use it in polys and rat nasties?
On poly's moderate to even heavy soil, it works pretty good. For the really bad ones I having been using
Saigers Code Red lately. I like the fact it has an oxidizing component in it. Helps a lot with residual coffee, water, wine stains, etc. The Procyon gets used in most of my residential and some commercial. If I need more power, I usually
crb or rotovac. The Procyon may not be the most powerful product in the world but works good, has no foam, dries to a powder, more people and pet friendly. Most of the time, I have no need for the super power products but I carry them for the odd job that requires it. One of the things you want to think of is your own health. The super power products can create issues with your skin, breathing and general health. To be used with caution in my opinion. I once lost all of the skin on my hands due to a super product. 13 ph.
