If you've not yet set up your own derusting tank, you're missing out on one fine tool. All it takes is a container (bucket-drum-tub-pool!)big enough to immerse whatever part you want to cleanse the rust from, and a battery charger. Then fill your container with regular old tap water and add a teaspoon of Washing Soda for each gallon of water. Find an old stainless hub cap or trim piece and hook the positive lead of the charger to it. Let it sink to the bottom of the container. Then suspend the rusty part (Steel or cast iron stuff ONLY!) in the solution so that it doesn't short out against the piece of stainless you sank in the container first. Now hook the negative lead of the charger to the rusty piece and leave it be for awhile. Hours - days maybe if it's HEAVILY rusted.
After a time though, pull up the rusty part and rub at the rust with a finger. It should rub off pretty easily. In fact, this treatment will float most old paint off too! Pretty slick. Once it's softened the rust enough, remove the part and use , brushes or scouring pads to easily brush off the softened (kinda gummy actualy) rust. Be sure to either paint the part or treat it with etch or oil to keep it from hazing over with oxide again.[}

I'm using a 50-gallon drum to do my rusty stuff. Man, you can do all sorts of things in that big of a container. Of course, the biger the part, the longer it takes a given amperage battery charger to do the job.
Also, while the solution may (will) get grimy after some use, it doesn't affect the efficiency of it. No need to change it at all. Just add a bit of water from time to time to make up for evaporation. Look for Washing Soda in the detergent section of the grocery stores. It's an addative for laundry washing.[8)]
