Default Re: Steel chassis resto How to ?

I had some some slight rust on the small steel clips that hold the glass dial on a Radio Rentals model 58.

I submerged them in some phosphoric acid that is used by caterers to descale kettles, etc.

After 30 minutes they looked like new, i.e. shiny.

The results you get can vary. Sometimes the rusty steel turns grey.
It may depend on the alloy.
