Cleaning trans case, what to use

[94whtlite#2669]

I need to clean up trans case before painting it. What would be the best thing to use before painting it. Going to brush paint it with rustled. Its not greasy, just oxidation.

Sandblaster, of course.

A buddy of mine used Awesome cleaner for dollar store put it in a big tub and dunked his heads in it covered and let sit a couple days came out looking like new.

Oven cleaner from dollar stores work pretty good

It's still assembled, it's a t5. I will try oven cleaner first, than will go from there.

I hate to contradict Billy, but aluminum and oven cleaner don't get along. Been there, learned that. It will etch the aluminum pretty aggressively. It's a strong caustic. It's great for steel and iron, though.

I'd just use a good engine cleaner/degreaser.

Paint stick to it then tho

When I wash an engine block, I use a generous amount of dish soap like Dawn, in a bucket with hot water, and scrub it with a scrub brush and rinse with hot water. For the stubborn spots, I hit them with engine degreaser or brake parts cleaner.

When I wash an engine block, I use a generous amount of dish soap...engine degreaser or brake parts cleaner.

Those aren't very effective on dry Aluminum oxide.

I used a can of foam degreaser, hit it with the power washer. Used Alumibright let it sit soaked a second time power washed and it was super clean. She is painted black now.
