I NEVER use a HIGH psi sprayer on any vehicle under the hood.Had PLENTY towed in with MAJOR/minor issues after a qtr car wash.Shoves water into areas(connectors for one)that it would never get into. Car wash spayers will peel skin and or inject water into the skin.Seen a lot of shorted sensors and ECMs because of engine cleaning at the qtr. wash.

 

Man, thought I was the only person who knew about that stuff. That purple stuff rocks, smells good too. I use it for all my inside/outside the house cleaning

 

Yep, Fabuloso is great stuff. Did an excellent job of removing ATF+4 from the engine compartment and underneath the truck after the hydroboost line let go while traveling 70mph down the freeway.
