rust stabilizer/converter?

I've used this:



They also make a brush on version.

This stuff works and Harbor Freight carries it, or at least used to. It is easy, just pour up some in a plastic container and drop the parts in. It'll take a day or two, but it converts the rust. Just rinse, dry well, and paint or seal with clear. You can use it over and over again.


ETA: But it may not give the look you want. Try it with a test piece and see.

Phosphoric acid is what you want. It's the active ingredient in most of the rust converters and it's pretty cheap. Just google phosphoric acid cleaner. Most stores sell it in some form or another as a concrete or tile cleaner.
