How to clean undercarriage

This is the way we did in the ARMY !!!

 

Look at hose attachments for cleaning gutters. Been using this for a few years now. Head pivots and is easy to redirect by bumping it up against the undercarriage. That let’s me spray in different directions to get the salt and mud from different angles. Meanwhile I stay standing several feet away.

Few pieces of scrap PVC pipe and a couple hose fittings.

Used it on last 2 trucks, and Jeep I had that spent a lot of time on the beach.

 

Toothbrush?

The problem is that you really need to scrub the area or else a film of dirt, dust, and salt remains.

 

If you are just removing road salt - I use a gutter cleaning wand to reach under and give it a good soaking with the garden hose. It would remove most dirt and mud but of course some would still remain without wiping down the area with a bit of soapy water. It is very effective to dilute the road salt in about no time.

Caution: Simple Green is corrosive to aluminum. If you must use it, consider their “aviation” formulation - not corrosive to aluminum.

 

I've washed off the heavy mud in the past just getting on my knees using a garden hose...i've got a pressure washer to that i've used.

 

Dawn dish soap and purple power in a foam gun. I then spray under the entire underbody, long brush and handle works like a charm, then a good rinse with a gutter water wand, leaf blower to dry it and a nice silicone spray does wonders, make the next cleanup easier and prevents rust. My undercarriage looks as good as day one.
