Soak the entire piece in pineapple juice ... seriously !
Scrub with a non abrasive brush every day; let soak until rust is gone .

DO NOT attempt to grind off the rust .

First rule:
Do no harm .

Pineapple juice? Are you serious?

So a small tub of pineapple juice, soak it entirely, and scrub a bit everyday, and keep it soaked in between until it's all gone... what do I do with the stickiness of the juice?

What's the advantage of pineapple over WD40? Gentler on the metal?

Cause I have WD-40, but pineapple.. I'll have to go buy one... which wouldn't be a bad thing except I'd have to squeeze out the juice and eat dried pineapple... OR buy pineapple juice (presumably with no additives?).

It is a acid any similar acid will do. look in the kitchen any citrus will do the same thing. lemon,lime, kiwi, etc

I use lemon acid and a brass scrubber carefully. Pineapple is more soft.

I'll think it over, and whichever solution I use...
I'll definitely proceed with care and caution.

I'll post photo up when it is clean of the rust.

This is pretty basic chemistry. The strength of the acid and the concentrate of it are what make the difference. The same acids that are taking off the rust can be used to etch just takes a while. Other ones to play with are vinegar,wostershire sauce,ketchup,urine. As long as the mix stays away from oxygen it will work. Another thing that is a good idea after a acid wash is done is to soak the metal in a oil. Olive oil is a good one to let it soak in for a few weeks and then clean it and wax it.
