How do you wash undercarriage?

I usualy go to one of the high pressure washes and do the under carraige.
I want to buy a pressure washer eventualy. I do spray the under carraige
with a All Season dressing and use it in the wheel wells to. I find it last better
than the waterbased dressings in the wet enviroments.

Crawl under there with a few wash mits, a few rags for the suspension components and a bucket of soapy water.

I actually enjoyed getting soaking wet cleaning her underside.

See ya on the road,
Matt
