don't use castrol engine degreaser, it will turn it pink

id prolly go out there with a bucket of dawn in warm water, a scrub brush, and a waterhose. or you could use some gas or brake cleaner with an air hose.

I had a buddy with a very dirty undercarrage use a can of cheap brake cleaner. Sprayed it on and waited like 5 mins then hit it with the pressure washer. Took everything off.

yup that brake cleaner is a great cleaner for getting grease everytihng.

its kindof expensive but brake parts cleaner will clear all that shlt off or walmarts engine degreaser works allright you still have to scrub it with something though....

Use some non-chlorinated brake cleaner, very potent.

There is this stuff I forgot about and it hard to find called purple stuff, not the purple power you can buy at auto parts stores, that will take anything off, but I am not sure if it will harm the aluminum. If you do find the stuff don't use you bare hands with it at full strenght, it will burn!!!!!!

whenever i had my tranny out of the car i used oven cleaner on it (just bc it was laying around the house) and it cleaned it to look like it was brand new. I was really shocked at the results. no scrubbing or anything just sprayed it and went inside for about 30 minutes and came out and rinsed it with a water hose. Worked fantabulous :-)
