Cleaning Undercarriage

San Diego, 

Hello I would like to wash my udercarriage, it's really dirty, there's a lot of oil sweat, and possible not located tiny leak with a drop under the left heat exchanger.

Does anyone have any recommendations on products to use, tools to use and technique that would minimize any damage while being effective against, oil grub, break dust and all that jazz?

My equipment is a small lift with 4 stands, so I'd have to lay down under the car. I have a pressure washer, water hose buckets and basic car wash products. 

Thank you.
