Hey guys, first post here on TMF as this is my first screw up on a couch thus far. This has been discussed before, but before I go back to correct this mistake
I wanted to ask opinions first. Onto the problem at hand, I recently cleaned a polyester material sectional client says they bought it as cosco, couldn't find a material tag
but did find the listing for an almost exactly the same couch on coscos website and it says 100% polyester (still not completely sure). I used TMF revive prespray at about 2oz for 60oz hand pump sprayer (couch was lightly soiled), evenly misted after checking for color fastness on back bottom of couch. Agitated with horse hair brush, let dwell and extracted with warm water (no rinse) at around 175 PSI, looked excellent afterwards however after it fully dried client sent me these pics. Please note I did post groom with HH brush when still wet after extraction. I have a standard 4" external jet upholstery tool (will be upgrading) , the 110 degree jet did fail about a week ago and I had a 95 degree or 9502 jet on hand so stupidly I used it for this job, is it possible the spray angle of this jet is too narrow and caused these lines almost as if I ran too high pressure on my machine? From what I have gathered, it wasn't heat (warm water only) or friction or chems that caused it so the only thing I can think of is PSI is too high, angle of nozzle, or nozzle was too close to fabric or both? Lastly, what is the easiest way to correct this issue to get it uniform again? I was thinking of using a rinse, and holding my tool about 5-6" away from the fabric, re misting brushing and dry extracting again then finish with a post groom? I would greatly appreciate any advice. Once pic is of the couch post cleaning before I left, the other is the pic client sent me.
