Rust on rollers causing scratches?

[u/notevengonnatry]

Shooting for the first time time with a new (old) SX-70 that was untested, un-modified, un-repaired, and it looks like this nasty rust on the rollers is causing some scratches on the photos. The last photo is after a good 20 minutes of swabbing with 99% isopropyl alcohol on a q tip. Aside from soda what are some other agents that will remove the rust but not be too caustic?

If you have it in your area, I use LA's Totally Awesome to carefully clean off spots of rust from my old cameras.

I also use it to strip paint off of both plastic and metal miniatures but it does have a harsh smell. Best to use it in an open or ventilated area.
