under vehicle clean products

I'm looking to clean under my tacoma, what products do people use and would recommend. I'm trying to not remove any protective coatings toyota may have applied to these parts under the car. I have a 2022 trd off-road.
I live in Northern California. I off road on dirt, sand & rocks. Rock climb as well.
Thank you in advance.

 

Soap and water …

 

Describe your location and the way you use your truck and your desired outcomes.

For instance, I don’t do anything to the underside of mine. I off-road, commute, and garage my filthy, scratched up red truck in beautiful Southern California.

 

@Malvolio thanks for the suggestions. I updated the description.

I use the spray your self car washes. I use the spray soap underneath, the foamy brush, and I use the spray wax option under there also. It doesn’t last long. I washed my truck the other day, and then went off to a trail…
