Cleaning aluminum/magnesium engine parts

[Fahren Cars]

Does anyone have recommendations on ideal methods to clean aluminum and magnesium parts to remove oxidation without tumbling?

I'm thinking about ultrasonic cleaning some 911 and 914 components. What are your favorite cleaning solutions that are also safe for aluminum and magnesium?



Photo for reference. Lots more parts than this. Thanks in advance.

Are you sure the parts are aluminium and not magnesium? Each requires a slightly different technique.

Good point. I have a mix of both aluminum and magnesium parts. I have miscellaneous parts from CIS, intakes, cam followers, chain covers, and more.

Those are both magnesium, and both RH housings.

With (somewhat less) corroded mag, I've had success with

Gibbs and a soft bristled toothbrush. You will love your parts after that

From what I know, there are some cleaning bath procedures that you can use. For instance, you can use the ultrasound cleaning technique. I have never used it. However, I have never heard any bad reviews about this cleaning method. Still, I recommend you get in touch with people experienced in this field. For instance, you can look for a good local cleaning company and give those guys a call. Or you can ask someone to give you a recommendation about a cleaning company which he has already used.

Gibbs is great, but I have been using Boesheild T-9 more frequently. It maintains the mag longer in my experience.
