How to clean aluminium hollow rivets

Q. Do you have any process for cleaning of Aluminium Rivets?Rakesh Shah
A. Hi Rakesh. Please don't simply start over after an answer has already been offered, but tell us your situation and in what way Mr. Gargatti's answer was inapplicable or incomplete for your purposes. Will you be shipping the rivets after cleaning, or painting/powder coating them, or installing them, or what? -- it affects the suggested cleaning process.
I think Mr. Gargatti's answer was a good first step: use a centrifugal spin dryer to fling as much oil out as practical. Then you can optionally vapor degrease them in a basket if allowable and practical. Then you can put them a plating barrel and immerse them in a non-etch alkaline cleaning solution, followed by rinsing, then back into a spin dryer for drying.
