I have a floor jack but no jack stands. I guess I could do one corner at a time. I also have a 3100 psi pressure washer but not sure if it would be wise to use it on the undercarriage. I found out he hard way the pressure washer will tear up the window screens on a house.

Thanks in advance.

I fabricated the wand for my power washer with a 90 degree where you would insert the various size tips.I use the detergent injector to soap it up and then rinse.
I turned the pressure down low Works pretty good
It never is really that dirty just some road dust

I cleaned the underside of the car with a product called "aluminum brightener". NAPA store was the only place I could find it. It is an acid base, so take care (don't open the lid and smell it, take my word for it). Read and follow instructions carefully. It probably took me 3 applications to get this clean. Rinse THOROUGHLY after each application. I have had no side effects from doing this, but I rinsed for 15-20 minutes to make sure it was all rinsed off.
I use ArmorAll on my rear diffuser. Plain old original ArmorAll.
Not sure if the exhaust is chrome plated. I think they are. They are B & B Fusions.
I also use Mothers Mag Wheel Polish on the exhaust. Then wax with Meguiar's NXT2.0.

After the application, how long did you let it sit before starting the rinsing? Did the water run-off (with acid-based solution) require any special precautions?

Thanks for the info. When reading for the 1st time my immediate reaction was "what about rubber bushings or similar and how did they hold up to the acid-based cleaner?" But, you state no side effects so I'm guessing the solution has a good balance of effectiveness vs. causing deterioration on soft rubber or urethane parts.
No deterioration of anything. I used this 3 years ago.

This is a mild acid. It did not even kill the grass where it ran off of my driveway.

I certainly understand the caution of using an acid based cleaner around anything rubber or composite. I read the directions thoroughly and followed them very closely. I used this 3 years ago and have seen no deterioration on any part under the car. I'm not advocating for the use of the cleaner, I was asked what I used. And I did this in my driveway BEFORE I had a lift. It did not even kill the grass where the runoff was. I sprayed it on the parts I wanted cleaned, and then thoroughly rinsed, and I mean thoroughly.

I'm not a chemical engineer, but:
- A lot of acids have little or no affect on numerous plastics, such as battery cases and the plastic bottles some acids come in.
- I wonder what the composite spring is
composed of? 
- Water is the universal neutralizer of most acids.
