There are a couple of good ways, but the way that I have found most effective is to crawl under the rig with a hose/pressure washer and go to town. Some guys park over the sprinkler, and that seems to do a decent job. However you do it, make sure you do a REALLY good job on the brakes! (Made the mistake of not getting them that well once... Expensive mistake! )
I usually pull it up on ramps in the front and then go to town with the pressure washer, then I flip her around and do the same with the rear. I like the sprinkler idea though, I might have to try that this summer.
There's no "easy" way. Even after pressure washing, I had to crawl under and scrape things out with my hands or a tool (putty knife, screwdriver). A lot of brush, especially desert brush (tumbleweeds), seems to want to stay put.
This dosent exactly pretain to the cleaning of the cleaning of the undercarriage, but i read in a another thread somewhere about "metal brushing" and painting the parts down there. I've been looking at paints recently (for flares, window triangle, trim...you know). Anyways, I ran across a product made by Krylon, Rust Neutralizer, has anyone used/ seen this used before? Does it work as well as that picture they have up on the right? The other post just used cheap black spray paint, but I figured if you're guna do it, do it right. Any input is appreciated
The best way is to drive through puddles really fast, instant pressure wash.
If there are no puddles of sufficient size then pull into the car wash, run your winch line upto the rafter, winch Jeep to attention and commence to hose'n.
Sprinkler works good, just gotta give it some time. I tried the baby oil this past summer and that is the way to go. Makes clean-up quicker and easier. I trailer my jeep when I go wheelin, and I just stop by the local car wash on my way home and rinse off the Jeep and trailer.
