I purchased a C5 fairly recently and looks to have been offroaded in the sand dunes and never cleaned… caked dirt all on the underside and really much of the car.

I will attempt a mass cleaning soon on jack stands and my thought it to spray underbelly with super clean and then spray with water. Much of the areas are hard to get your hands on.

Any suggestions? Maybe there’s a smallish high pressure wand that I could maneuver while under the car on jack stands.

I myself would use 'Simple Green'. It is not as caustic and the super clean can be if it gets on aluminum parts.

Wet it out...let it sit...wet it out again...let it sit. This will aid in softening up the baked on crap.

Yeah super clean is potent. I'll prob try compressed air first before getting under there with cleaner/water. Renting a lift where I could spray water would be awesome.
