Alright carpet nerds...After a year of purposefully testing this I'd like some answers or explanations...
What is the purpose of the 20 minute dwell time? I've had trashed carpets that clean up almost perfect right after pre-spray and rinse.
When I used to do CRB cleanings I noticed my pre-spray worked better if I agitated IMMEDIATELY while spraying. If I waited 20 minutes it was not as effective.
I had the mother of all tests the other day, I should have taken pictures. A polyester frieze, had not been cleaned in a year, 5 dogs in the home. Carpet had that horrible black square around the coffee table where the dogs lay and track into and outside of the house.
I was using Procyon and Flex Citrus-Solv, 1 scoop each in a 1/4 filled inline sprayer. One side of the room I sprayed and let dwell for 20 minutes. Meanwhile the other side of the room I sprayed and rinsed immediately. Truckmount was Blue Line Blue Wave, 200 degree heat at the truck (no measurement at wand), no pre-agitation, using Rotovac 360i. PSI set to 320.
Side A (Spray and Rinse Immediately): Took me 15 minutes to clean, had to spray and rinse all of carpet twice. Came out 95%
Side B (Spray and Dwell 20 Minutes): Started cleaning after 20 minutes, did not look as good as Side A after first rinse. Sprayed and let dwell for 10 more minutes and rinsed again. Still did not look as good. Sprayed and rinsed immediately, looked as good as side A. Total cleaning time 40 minutes.
Is the dwell time not as important for polyester due to its hydrophobic properties? Is it better on Nylon? What's the deal!?!?!
Extrapolate this to every room in the house and sheesh that would be a long time on the job!
