There's no simple chemical fix.
There are tons of products on the market, and almost everyone thinks they have the uber-secret ultramegarustfix technique using some kind of special blend of obscure chemicals. "It worked for my Uncle's friend's brother, it's definitely the best!" Don't waste your time.
Short of dipping the entire rack in a tank of acid, the best possible way to fix any rust is to mechanically remove it, then properly prime the clean bare metal and top coat it to prevent corrosion in the future.
I'm assuming you don't have a full shop of tools to work with, but you can probably find a battery drill. Get a wire wheel like this there on Amazon or at basically any hardware store. Put it in the drill and go to work. Just remove all visible rust. Use a maroon paint prep scuff pad to scuff the surface of the rest of the rack. Wipe it down with wax and grease remover.
If you don't want to go with the drill and wire wheel, just use 180 and then 320 grit sandpaper. That will take care of it. I just prefer rotary tools whenever possible because hand-sanding always sucks.
Your choice in top coat paint will determine the best course of action following removal of the rust. I'm an automotive painter, so I always recommend going with 2k catalyzed automotive materials for the absolute best in durability other than powder coating, which is much more expensive.
You don't have a lot of rust there, so not much will be bare metal. You can get away with simple non-catalyzed self-etching primer rather than epoxy, which is tougher. Spray a light coat or two of etch primer over the bare metal, let it dry, then scuff with the same maroon pad. Wipe down the surface with wax and grease remover again, then top coat.
I'm assuming you want the rack black again, so I'll recommend a catalyzed chassis black paint.
That's exactly how I'd do it. You'll end up with a very durable, good looking surface.
3m metal cleaning attachment for a power drill after a little degreaser soak. I'd just use elbow grease but 75 to 100.... go to home depot and spend 10 bucks, grab a power drill and unleash the fury dude.

Put a bolt thru it tighten it with a nut and put it in a drill chuck.
Should look/work like this.

I tried an assortment of brake dust cleaners and even brake parts cleaner with no luck so I resorted to a relatively soft wire brush attachment for a drill.
This was a last resort for me. It was between this and new wheels. I’m very happy with how they turned out.

It didn’t scratch the wheel at all. I even used it on the front of the wheels and it didn’t scratch the paint. Turned out 1000x better than anticipated. Took about 2 hours for all 4 wheels including the time it took to jack the vehicle up and down.
Side note: If you wet the wheel down first it seems to work better.
Honestly, just use a drill and wire wheel. Anything else is overkill unless the calipers are incredibly pitted, in which case you’d almost certainly do better to just replace them.
One of these and one of these or go nuts and get one of these and save yourself some time. (Obviously you should order more than one wire wheel at $4/each)
The wire brush suggested by WWD should work. I had the same problem with the paint in the small grooves and brushing them looked tedious to me. So I used a wire brush attachment on a drill and saved some time/elbow grease.
