Cleaning aluminum transmission case
Hi There,
I've been lurking for quite a while and finally have a question for the collective.
I recently removed the engine and transmission from my speedster replica.
The engine and transmission are aluminum.
I was wondering what cleaner should be used to clean the exterior.
I have powerwashed the transmission, and used a citrus based engine cleaner, but there is still black 'sludge' that won't come off.
I also want to polish the case when it is clean. What procedure is recommended.
Thanks,
Tenzin
