Matt please stay focused on the topic at hand. :rolleyes: And yes I have had a few name changes but that was encouraged by Don to make it J Thomas. My name is Jarrod Thomas and it just makes sense to him. I can respect that.
Suggest you check w/ the guys that make the vibratory cleaners as they have proprietary stuff for various applications. I recall having seen some of them at trade shows, but as I had no current need, didn't collect info. If I were starting from scratch, I would be inclined to try TSP from the paint store.
(edit on re-reading OP)
Are the oxides on the parts or on the aluminia media?
