I use driveway cleaner that I buy at Costco. This is very strong though
you can cut it with water. If you have shiny aluminum the driveway cleaner
will remove the shine in a heartbeat. I spray it on with a spray bottle,
let it sit, use an inexpensive paint brush to massage the big chunks, wash
it off with low pressure cold water, and, if needed, use an air hose to
blow off any remaining water. The full strength driveway cleaner is strong
enough to remove (without intent) the paint from the frame of my S10.
Using high pressure washing around electrical engine components can create
a problem with connectivity.
