Best method to remove undercarrage grease

[RKL]

On my 02 Journey I have alot of flung grease on the undercarrage and wire looms from the 2 universals. What is the best method for removing it.tried spraying with a degreaser and brake cleaner and rinsing but alot remains. Thks. Rkl

The u joints on my old Journey is why I named it the Greasy Beast.

Maybe spray it with Gunk engine degresser?

Steam cleaner.

Wipe off the big chunks with some paper shop towels and then try some brake cleaner with a drain pan under the low point of the frame so you don't damage the driveway/pad/grass under it.

If you wiped the major clumps off, why sterilize the rest of it? Unless you need to access the wire loom I'd leave it as rust/water proofing. If your dog likes to hide under the motorhome, well, then clean away, but using all sorts of degreasers and harsh chemicals can't be good for the plastic and rubber under there.

Thks guys. Main reason for degreasing was to uncover the air dryer for servicing. It is next to the u joints on the driver side and catches all the fling off grease. It has to be romoved from the mountings to service....go figure.. Going to the shop next week. Need it on a lift to remove. Rkl

I bought the replacement filter, and was going to replace it myself. Then, fortunately, while the motor home was in the shop having the transmission fluid replaced, I just asked the shop manager if they could put the new filter in for me. The manager did it himself, and came out from under the motor home with grease/oil covering his arms from hands up almost to the shoulders! It took as long for him to clean up as it did to replace the filter! It's worth paying someone to do it....
