Thanks all for the replies.

Yep, that was it. If you look up the properties of alodine you'll find that it has corrosion inhibiting properties as well as acting as a surface preparation prior to painting. It's the chromium content in the alodine that does the trick. The gold standard for corrosion protection in severe environments would be alumiprep (or similar), alodine and then epoxy primer (2 part). What bbs428 has done will have a similar effect - the vinegar will help reduce some/most of the oxidation layer. Alodine 1200/1201 is a pretty good inhibitor, and it'll also maintain your electrical conductivity. I decided to go this way because it's way simpler than priming. As bbs428 says, you can slosh and wash (water rinse) .... and you'll have good protection .....
