Cleaning The Underside

bmg9b · **Posted:** Thu Sep 07, 2006 11:43 pm

Hey guys!

I wheeled my KJ for the first time tonight and I was wondering if anyone had any usefull tips and tricks for cleaning the underside of my Jeep. If anyone has a process that seems to work well for them, please share that too. I've never cleaned the underside of a 4WD before.

I used to own a airbagged trying-to-be-show-truck S-10 pickup, and I was ANAL about getting the underside spotless. I do know that if you powerwash it too close it strips the black protective finish off of the frame. I ended up having the frame powdercoated after that little incident. That cost a pretty penny.

Anyway; thanks for the info!

park it some place that getting mud on it wont matter ,like the lawn
place a lawn sprinkler under your jeep and turn it on full blast
doing this will kill 2 birds with 1 stone clean your jeep and water your lawn

I usually pull it up on a curb at the house and pressure wash it all really good. Ive never had a problem taking the black paint off?? If i want to get it really good, Ill add soap to the feed in the pressure washer.

Power washer works well. However, if you really have LOTs of mud I find it is best to take off some of the skids. Mud has a tendency to really clump up in there and it is hard to wash out. Especially the front skid plate.

Before going "mudding" spray some baby oil, WD-40, cooking oil underneath the body. This will defiantly make it easier when washing off all those pounds of mud. I've used the sprinkler method to clean it as well.

I put mine up on my ramps do the back first then move the ramps to the front, also take all skids off usualy I just use water sometimes simple green

Yea, if its really bad Ill climb under and pull alot of the mud out by hand. Then ill spray it all out really good.

You can pull the mud out of your rear bumper too.

OK, so I cleaned the underside today. Tomorrow I'll do the outside/detail and interior. Anyways; I used some "Power Purple", which I'm guessing is like Simple Green? It's what my dad used to use on... everything. So I sprayed everything and let the Purple stuff sit for maybe 5 or 10 minutes, then I used a wide spray on the hose nozzle and tried to get everything I could. Then I sprayed in all of the hard to reach places using a bunch of different angles to get as much as I could out. I kept spraying until the water went from red (VA Red Clay… it sucks), to cloudy, and then finally to clear. I feel pretty satisfied that I got all of it out that I could. Then I used a white cotton rag to get the wheel wells nice and clean.

And by the way, the Purple Power stuff is biodegradable.

Thanks for the advice guys…

Ive been meaning to get some of that stuff. Ive heard its really good.

It does a real good job. I use it to clean up motor oil spills when I change the oil in my Jeep, since I do it on our carport. I just spray a bunch of it on and let it sit, then hose it off real good. I feel better about the dogs being arround it since it's supposed to be pretty safe.

OK guys, here's the finished product. Sorry about the crappy pictures. There isn't a single AA battery to be had in my house, so I used the little web cam thing on the top of my laptop. My neighbor kept looking at me funny when I was taking them...
