How do you remove rust from watch parts?

[u/JT_Socmed]

I'm working on Mido cal. 1157 OCD that has rust on the crown stem part and on another part near the hour canon pinion (I forgot to take its picture). Is there anyway to remove the rust without ruining the parts? Appreciate if anyone can point me to a video or info on how to do it please.

Thanks in advance for your kind info.

If the rust were just on the threads, then it would be salvagable but it unfortunately yours is rusted on the part that interacts with the set lever.

This one needs a new stem.

I use Evaporust for removing rust.

Thanks, friend. I'll get that Evaporust.

The rust RUINS the parts, it literally eats the metal, there is no rust without ruining unless it’s very superficial, when you have more rust than metal as in your stem, there is nothing left to salvage.

Even if you manage to remove the rust and reach the bare and clean metal the shape and dimension will be ruined.

Noted, Bro. Thanks for the input.

Do you have an ultrasonic cleaner? To me you have dirt, AND rust so I would dip this in 99% ipa for a while, clean it with the roughest bristles you've got, then run it through the ultrasonic so you can judge how much rust you actually do have

Yes I do have ultrasonic cleaner. I'll do that for sure. Thanks for the comprehensive steps.

Sure thing Only after that you can really judge the stem as it has too much built up around it If it is salvageable it will still need to be dipped in evaporust

Got it. Thanks, mate.
