I'ts loaded or mostly STPP which is very corrosive to brass.
I like procyon, but you need to carry something hard core for a back up for the times Procyon wont cut the mustard.
Although it has surprised me at times and cleaned some real filth holes extremely well. You just never know for sure how its going to work, sometimes amazing other times it's nothing.
Scott, I'm curious,, how do you feel stain resist compares to procyon, and master blend soap free?
Not mostly, more like 100% in their base formulation.
The product is logically compared to flour as part of a loaf of bread.
Much in the same fashion that most powdered emulsifiers in this industry are composed with a large percentage of STPP. Those other formulations simply contain a variety of other compounds to increase performance (i.e. surfactants, other builders, co-solvents, corrosion inhibitors , etc).
Most users of Procyon find they have to add a mish-mash of other additives to achieve satisfactory cleaning. even the use of a good prespray is far better than can be achieved with STPP alone. Really the genius of Procyon is in the marketing.
Why do some cleaners like it? For the same reason Zerorez appeals to Mrs. Pifffelton.
Water rinse works better because if you use a detergent then you are leaving soap behind witch causes quicker resoiling.

Hmmmmm - This was cleaned with NO prespray and 5 ounces of SS rinse to 15 gallons in a porty.350 psi (I took those pic's to tick off Lee Stockwell- a spray and clear water dude.) Now envision the added ability of that cleaning punch WITH a good prespray and agitation and a good rinse solution. Now think about your recovery rate. How much detergent is left in the carpet? a very minr amount and if it;s a powder.... Red herring?
Sooo- How much dirt are you leaving behind by NOT using detergent in your rinse?
Granted the detergents in your "rinse" were better than your prespray from the pictures.
I started doing clear rinse after a Monsanto engineer told us their preferences.
Willy, after you finally get it clean how much chemical is left behind?
