I figured this would help several here too.
I used Lysol brand liquid Toilet Bowl Cleaner. Others have used The Works Brand from the dollar store.
I have been bead blasting and painting with VHT paint. There are two things I don't like about that.
1: It removes all of the original finish.
2: I don't care for the color.
There will be times I still bead blast. But; I like the more original look of this method of cleaning.
This is what I did.
I took a gallon size plastic tub. (I plan to buy a heavy 2-3 gallon bucket with a lid for the future.) Filled it most of the way with warm water then put a liberal amount 1/4 to 3/8 cup of cleaner. Mixed it up and then put in the rusty parts.
I let them sit for 15-20 minutes then pulled them out and scrubed them with a Scotch Brite type kitchen sponge. On the tougher crud an SOS Pad. Brass takes maybe 5 minutes.
I plan to save it and reuse it.
Here are some before and after pictures.
