Will, is it rust, paint, grease or? that you're trying to remove? Also, are you trying to keep the galvanizing?

I have used a weak solution of muriatic acid. You dip or spray the part in a 20:1 water to acid ratio, but just for 3 to 4 seconds at a time, then immediately flush with plenty of water to stop the acidic action. It will remove a slight film of zinc, but leave it looking like fresh galvanize.
Usually one or 2 times does the trick.

Vinegar will clean galvanized metal. Plus it's fairly safe to use.

Yes- The PH of white distilled Vinegar (Acetic acid parent) is ~ 2.4 while the PH of 10% Muriatic is ~ -0.5..

The Muriatic acid is much stronger and the hazards presented by it much greater. (Hydrochloric acid parent)

So I'd try the vinegar first and see if it works.. Good luck!

Thanks guys.
The parts are the linkage rods for the brakes, and gearshifts on the Elf.
They are just looking a bit dull(tired).
I will try the vinegar. Acid scares me.

In the shop we would etch galvanized metal with vinegar before painting. Works great to both clean and etch.
