I don't think Stanley should be listed as an approved service provider, at least not my local one. I actually had them over to my house to clean 3 rooms as part of my pre-business startup research. They did not follow
IICRC standards, and they did not follow the procedures CRI listed for them in the Approved Systems Section.
Here is the CRI approved System for Stanley Steemer:
"Stanley Steemer's Truck Mounted Model 5450 with Wand
Stanley Steemer's Truck Mounted Model 5450 with Proprietary Wand and 2 inch hoses pre-vacuum 4 passes; Prespray with Stanley Steemer 2X concentrate 30:1 as an in-tank rinse using 4 wet passes and 2 dry at 1ft/sec."
Well... they did not prevac... they did not prespray....and they did not use that many passes.
So, if they are not even following their own "approved" system... why are they listed as an approved provider?
