Morbid curiosity got ahold of me and I decided to see how well the carpet could clean up. Soaked it in vinegar and hit it with the pressure washer. All kinds of disgusting junk came out. Surprisingly, there is very little rodent smell in the carpet now. It's there and faint, but it's not disgusting. I've let it bake in the sun, and I'll probably hit it again with the vinegar and pressure washer. It looks like new carpet that was installed and then the project stalled, and that's when the rodents moved in.... Thankfully, they didn't chew the carpet. Only the extra insulation that the previous owner added...I may end up using it in the yellow truck, since the original rubber mat is pretty brittle....
