removing rust from "new" parts and polishing aluminum, tips?

[strangersinspace]

I just got some old stock NIP transmission parts that have rusted in the package over time. I've read about using vinegar, WD40, CLR, etc. Is there any consensus on a good way to get rid of the rust? Do I need to do anything to the parts after removing the rust to prevent it from coming back - I recall using a dremel to get rid of rust on a set of dog bones and the rust came back even worse than before in a short amount of time.

For aluminum... I have some shocks that I've stripped the anodizing from. Can I just use a dremel with a buffing attachment to shine those up? What kind of polish/compound should I use for that pupose?

Thanks!

I use evaporust when I remove rust from parts, tools, small metals stuff. Its available at Harbor Freight and elsewhere. IT works just about like vinegar, but in my opinion slightly better. If the rust is pretty minor, vinegar will work. I usually treat the parts with either a wax product (tools) or wd-40 for smaller surface area.

Oh and evaporust is reusable so Ill often strain it and reuse it again.

Leave it in too long and you will get a nice black coating, so check the parts from time to time.

Best part of using a chemical, evaporust, vinegar, naval jelly, is that it doesn't ususally disturb the not rusted portions of the part like a mechanical method does. This should help prevent extra rust from forming in new areas. Mechanical methods will often cause extra rust because they remove previous coating in extra areas.
