PB Blaster I have found to be pretty good at getting rusty things
losened then you can go at them with other stuff.

I acquired a monster chain-type come-a-long and am
currently soaking the chain in a (covered) bucket of ATF
and acetone. We'll see... It took most of a gallon of
used ATF to cover the chain. I put a bit less than 2
cups of acetone. Maybe not enough - but I'm cheap!

If you can get the chain out of the come-along the best way
to clean it of rust is to put it into a small electric
cement mixer along with a couple of shovels of sand. Worked
for me a couple of times now. Soaking it in oil doesn't
really get any rust off.
The chain on this is a roller drive-type chain. Think
bicycle or motorcycle - but _big_. It is only slightly
rusty. At one end of the chain I use ATF and some movement
and got the chain flexing well. My objective is to get oil
into the joints so they will move - probably will require
some elbow grease.
I have disassembled, cleaned, and lubricated the drive unit
and the block. Once the chain is flexing well it should be
fully operational. I don't know what I'm going to do with
the monster then.
It's a Yale PC series roller chain lever hoist. The roller
chain is not very flexible side-to-side, but super strong and
long lasting. Though it's rated for 6000 lb [2700 kg], it
sure looks like it could lift triple that.
The pictures are crummy, but kinda mine looks kinda like this listing.
