I've been working on my Aspen Progect & thought I'd share some stuff that works preatty NICE! It's called "Mean Green" not "Simple Green" it's a great degreaser. I used it on my door gaskets, warsher fluid box & all engine hoses. It comes in a gallon jug I got from Dollar General for $5 + a coupon to send for a Free one. I sprayed on let it sit for 20 min. & warshed clean. On burp jug & warsher jug I sprayed the outside & fill 1/4 full inside a shook it up, let it sit and Wow clean as clean. Alot less work that the Mav warsher bottle was! If you try it I think you'll like it Too! Also remember a good hand cleaner (I use Napa) rubbed into you rubber door gaskets will bring them back to life like New. Good Luck!
been using it for years..... used to only be able to get it at a Dollar General store but now the local Walmarts have started carrying it.
