Maybe I'm not fully understanding the problem, Madavan, but it seems that you can either bead blast it or chemically clean it. If you chemically clean it, what you need to do would depend on the nature of the soils and contaminants, but probably scrub with pumice ⇦ on eBay or Amazon [affil link] and water, then rinse with isopropyl alcohol ⇦ on eBay or Amazon [affil link] . If that's still too much water, dry it in a vapor degreaser. Good luck.

Do not dry parts in a halogen based vapor degreaser unless you want a severely pitted unit that will cost a fortune in stabilizer breakdown and eventual replacement of the unit.

I'll concede that drying parts in a vapor degreaser creates HCl, which is bad for the degreaser, James. But it has long been a common procedure for electronic contacts and other parts of complex shape where contaminant-free drying is otherwise problematic; and some shops have dedicated units that are used exclusively for drying.
