Quite some time ago, I posted a request for information on possible cleaning solutions for parts in an ultrasonic. I got no responses, so this is wither inapplicable to you all... I will take the risk.

As you probably all know, soaking aluminum in many degreasers will stain anodized aluminum, my conjecture is that the small pores that the anodizing process generates absorb the dissolved greases and dirt through capillary action. Anyway, it does this with quite some intensity in an ultrasonic.

What I have found is that a fair concentrate of car wash detergent (this was a blue Westin concentrated liquid) works really well. I like to isolate heavily greased items like bearings, cones, axles and other ferrous stuff, so i set a jar filled with reglar degreasser (like simple green, soylent orange...) in the ultrasonic car wash bath and run all the parts together (but isolated by the jar).

Hope this makes sense...
