Ok I just got back to my xj project after a year on backburner. The seats are filthy!! I got the expensive neoprene covers for the front(will do back after umpteen other things), but I hate to just cover up dirt. This thing must of been a friggin shop car or something, they feel and smell greasy. When I welded in a new driver pan I pressure washed the carpet and got it looking good but I was afraid to hit the seats. Tuff stuff foam doesn't really phase it, any other suggestions? The seats are back in so pressure washing is no longer a option. Any suggestions are appreciated, I have a mean green machine but I'm thinking strong solution, scrub brush and shop vac is more in order

Take the covers off and throw them in the washing machine,very easy to do.

Hmm I'll have to look into how hard they are to take off I didn't think of that, I did want to sand and paint the bases so maybe I'll pull em back out and make it easier(after breaking and repairing seat bolts during pan replacement I anti seized the crap out of all the bolts)...thanks

Don't know what year you have, it should be similar.

+1... yeah, that!

I was in the same boat. I think the PO used the jeep to haul car parts around. When I bought it, it wreaked of gas, oil, grease and who knows what else. I ended up pulling the carpets (there was a very oily, greasy film on the floor pan throughout) out and removed the upholstery from the seats. Afterwards, I soaked them in a purple power/water solution for about an hour, then took the to a spray wash to rinse them as good as possible. Once I brought them back home, I threw them in the washer with detergent and oxy clean. I am very pleased w/ the outcome.
