So, I did a full interior detail today on my mustang and I ran into a problem. When I bought the car it had the dealer installed plastic stick-on covers over the floor mats, then the dealer mats over those. Well, the day I got the car I took the driver's side plastic off, but I left the passenger side one on for about 6ish months (pre-autopian) so that it would stay clean :grinno: . Anyhow, today my method for cleaning the floor mats was: I took them out, sprayed them down with the hose to remove excess dirt, then I used my spray bottle with foaming nossel to spray them with 3:1 TWP shampoo, then I scrubbed them every which way with a finger nail brush for about 10 minutes a piece, followed by a ton of rinsing, then "extraction" with a shop vac a few times, and finally dry in sun. Well, the driver's side one turned out great, but the passenger side one felt rough, like I had left soap in it, but I knew I didn't. I knew it had to be the residue from the plastic. So, I applied some of this carpet foam via aerosol, then more of the soap mixture and scrubbed a little while longer, then repeated the rest of the process. No luck, the carpet is still rough feeling and stiff. I know I was scrubbing the crap out of them and removing all the dirt, because I took a couple of stains out.
