Since I tore out my carpet and sent it to ACC so they could try to figure out why their carpet didn't fit my Windsor (they didn't) and I am waiting to hear back from Gary Goers, I thought I would see if I could get the old carpet clean enough to use in the mean time. My first attempt was simply blasting it with the hose to get the loose debris out. What surprised me was the amount of heavy white suds that continued to appear, no matter how long I sprayed (I am talking about well over a half hour total time). 

I finally decide to use some half strength Jungle Jake Cleaner and a scrub brush on the stains- probably ground it dirt and tar from shoes. It took out everything including some rust stains from under the sill plate.

It still isn't pretty, but I had nothing to loose. At least it should take a dye job fairly well, if I am forced to go that way for now.

Ian, Thanks. Are you talking about actual paint or the fabric spray?

I replaced the forward leaf spring bushing and the transmission mount. both were past their expiration date.
