Suggestions for cleaning corroded bridge?

[Slowhands]

Recently I changed string guage from 10s to 9s on my old 1990 Custom. In doing so I got a little buzz on the low E above the 12th fret. I think it's just sitting a little lower in the nut and I just wanted to adjust the saddle up a hair to compensate but the set screws are super corroded and don't really turn. The whole bridge is pretty corroded in fact. Not sure why it got it so bad because no other metal parts on the guitar (tuners, pots, etc) have any corrosion to speak of at all. But it's 30 years old so stuff happens.

Bottom line I'd like to clean it up so it's fully functional and stays that way. I don't want to take it off to do so though because I don't want to mess it up, worried about snapping one of those six screws in particular. I thought I'd just pull off the saddles and do something about them, if nothing else. Was wondering if anyone has any suggestions for good treatments to de-corrode the saddles, and what they'd suggest for them main bridge that would remain on the guitar, something that would help stabilize it from corrosion but no risk damage to the finish.

Any ideas? Pic of the bridge included below, for what it's worth. It's from some time back so I didn't zoom in on the saddle screws where the corrosion is really obvious. But you can imagine. Thanks!

As you’ve said, remove the saddles. The saddle/s that the adjustment screws don’t turn on, I would give them a good treatment of WD40 or similar. Failing that, submerge them in it until you get some movement.

As far as the corrosion, the chrome plate has worn off. This will continue to occur with playing, if you rest the heel of your palm in the bridge as you play.

It’s what referred to as patina.

As long as the saddles are functional, I would leave the wear (corrosion) alone.

Apologies if I’m telling you stuff that you already know.

I wouldn't get it on the finish until I knew if it didn't react with it, but it's great with loosening and protecting metal screws.

Thanks, I'll proceed with plan A of removing the saddles and cleaning / lubricating them and leave the rest alone so I don't dissolve or cloud up the wood finish in any way. Aiming for restoring functionality, not original shine.
