In the past I've bought phosphoric acid available under various brand names to soak rusty parts in. White vinegar can be handy in a pinch too.

I mostly use Evapo-Rust but I also mix up my own concoction of 50% Navel Jelly and battery acid. I've done entire floors with this and it works,for me anyway. I did the floor in this 63 Nova convertible,that's virgin metal in the picture,that floor was scrubbed mostly with small SS brushes,a lot of them.

I see people use rock tumblers. Do you put the navel jelly / Evapo rust in the tumbler or use some grit? Whcih grit?
Harbor Freight rock Tumblers are up to $70. Facebook Marketplace has cheaper ones.

Will they hold a solution without leaking?

Tumbling stone requires the grit plus water, so no, they don't leak. The "can" is usually made of a firm, thick rubber with a groove at the top where the metal lid registers. Then a wingnut secures everything together making it all leak-proof.

I am sure it depends on a number of factors like the amount of rust, the rust remover, ETC. But once you put the bolts in, Approximately how long do you have to leave it in there for the bolts to become acceptable?? Ball part it. An hour? Overnight?

Depends, if major corrosion just replace with new of equal quality. If just light surface corrosion, sometimes a coupe of hours, sometimes 4 or 5. I just removed my differential and support, half shafts, and drive shafts. Cleaned hardware in tumbler except for spring attach bolts, will replace them.

You basically hit my issue on the head, "new of equal quality". I may mistaken, but the old hardware seems to superior to the new "grade 8" I can purchase. In fact you can see the differnce in the hardware depending on where you buy it.

I saw this at Harbor Freight: https://www.harborfreight.com/6-lb-d...ler-59474.html Also, not sure how big that drum is.
I can’t tell if I can use a liquid like evapo-rust in it. It mentions dry media.
The National Geographic drum is so small it won’t handle most of the bolts:

👆is the one I have for coins, which I bought years ago before my vette. Think the one in the video would be best, but I’m not buying another.

Manual says no wet media
