Vinegar and sand paper.

Not an easy job.

Cleaning rust is not enough, you need to make them electroplated (zinc, nickel, chrome, etc.) or painted (some black covers for example) again. Rust means the plating is nomore, so there is no corrosion resistance anymore, and it means it will rust again after cleaning the rust.

Furthermore, if you want the original shiny surface, after cleaning the rust, the part should be polished to the desired gloss before plating.

Cleaning the rust is possible with the use of rust cleaning chemicals (WD40 is the most popular), brushing, acid bath, etc.

I see. WD40 or vinegar followed by wiping down with cloth, then giving the brackets a spray of gloss silver paint is probably the way to go I suppose?

I have improvised a home made sandblasting machine that works like magic on old cases. It clears rust perfectly.

I am using s compressor, A paint gun meant for treating the underbody of cars, but loaded with sand

Rusted components should be cleaned with either vinegar or citric acid. Remove components and submerge them in either chemical, if the rust isn't serious use a electronic toothbrush (normal one is fine aswell, but I am lazy) and clean of the rust followed by a spray of clear paint to keep the original colour. If the rust has already started eating away on the metal best is to just sand it down, polish it with wet sand paper and painting it.
