Engine cleaner

[Rawze]

for engine area or any other areas with wiring around it ...

I use diesel fuel in a garden sprayer (or charcoal lighter fluid) + paint brush to clean oily grime and to work it loose.

Followed up with de-greaser soak + garden hose pressure only to rinse everything off after getting it all worked loose, and to make it safe.

Any power-washing = wiring issues, corrosion, and problems down the road.
