was wondering what you guys use to clean a c5 under carraige, thought i saw a thread about simple green and scotchbrite pad to scrub the aluminum.

Once a year I try to clean some undercarriage parts and wheelwells specifically. I use Optimum PowerWash and a small scrub brush. I then coat the parts with Griots Undercarriage Spray. For the wheelwells specifically, you can paint them with matte black paint (use high temp paints) annually too as desired. Obviously dont use paint on suspension parts. If you have metal parts exposed that have discolored, sometimes some quad 0 steel wool and metal polish can make a difference too.
