The funniest line is the caustic acid in Oven cleaner. Cautic yes, acid no. without getting intot the pH scale here, an acid based material (solution) is low pH and an alkaline or caustic solution is a high pH matrial or solution. The alkaline stuff works better on animal (polar) grease than petroleum grease. Remember grandma's soap from school, that was made with tallow (fat) and caustic.

Something petroleum based will be best. maybe a plactic spatula to scrape of the major crud and some diesel fuel (that Gunk engine degreaser spray), which is close to kerosene and jet fuel, home heating oil etc. and a stiff plastic bristle brush, then some purple clean. Wear rubber gloves and splash goggles.

I'm glad I can amuse you! I meant to say caustic soda, it was late. It's guys like you that make people not want to contribute! Correct me yes, be a jerk, No!

Try ZEP, water base, but will even fizz aluminum if left too long. Spray and saturate on a hot engine or tranny with a pump sprayer and let it set NOT long enough to dry and pressure wash. Same with grease stains in concrete, don't let it dry, and pressure wash. Don't get any on your hands very long or you will be peeling skin off. Buy it at Lowes or Home Depot in gallon jugs.
