Cleanup of 'salts' on aluminum parts

I've been using a parts washer and soaking overnight/circulating the degreaser. As you can see in these pics of my cam towers and on the valve covers, there are lots of "salt" deposits. They are crystals, and in some cases are very well stuck to the aluminum. They come off with a scotchbright pad, but there are some spots I can't reach well. Carb cleaner seems to desolve them some, but not all and still need scrubbing. This stuff seems to be forming in the degreasing process, or maybe I just see it only after all the gunk is gone.

I am thinking there has to be some kind of solution I can dip the alu parts that will dissolve the salts easily, like baking soda/water, lemon juice, or ammonia.

Any suggestions? I don't want to damage the parts experimenting.
