I've never used this. However I recommend apple cider vinegar. I used this on my rusty brake parts and in 4 days they were all nice an shiney. I just found a Tupperware container, put all the parts in and covered them with the ACV. Cheap and easy.

After watching a number of the videos it looks like a safe viable product to use. I might try it next summer on my 68 corsair project that has flash rust.

Wow I did not know they produced Corsairs until the late 60's. I have always thought a vintage fighter plane would be cool.

Haven't tried Dr X either, but looks promising. Been using Evap-o-Rust regularly for over a year now though, and love the stuff!
Cleaned up many a part that looked like it was going to be a hard sell. But a little time in a bath of the stuff and I was a convert.

And when it's spent you just spray it over your lawn as a fertilizer. Not too shabby.

Didn't find DrX in the following list. For what it's worth, here's the list
of "10 Best Rust Rmovers".

If you research the ingredients of many commercial rust removers, you will find
phosphoric acid listed. It converts iron oxide (rust) into iron phosphate which
appears gray or black.

You can find phosphoric acid at any home improvement/hardware store. It's used
for etching concrete. I dilute it with water by about 3 or 4 to one.

Be aware of a phenomenon called "hydrogen embrittlement" which is caused by over
exposure to acid. I conducted an unintentional experiment for this one time when
I forgot about some rusty nuts and bolts submerged in a phosphoric acid solution.
After a month or so, I remembered them. They were definitely brittle and crumbled
in my fingers. Lessom learned.

Here's the technical detail for phosphoric acid use as a rust converter:

I personally use the Prep N Etch for a lot of things. It works great.
I also have tried the Rustoleum spray on gel for light rust.
Using either with red scotch bright on lightly rusted items can bring it back to nice shiny rust free metal.
Heavily rusted items work best when blasted. I sometimes will blast and if any rust remains in the pits I will soak the item.
But that is another point.
Most of the chemicals work best when you can soak the object in it. Merely coating it with the chemical does not work nearly as well even when you keep it wet.
My rule of thumb is to NEVER use the chemicals on heat treated or spring steel as it will ruin the item. So no nuts, bolts, washers or springs on any type.

Another point to make is that prior to rust removal, you should degrease the item.
Contrary to what you might think, acid does not remove grease. Sodium hydroxide,
e.g., Easy Off or if you want to go medieval, Drano in solution.

Now it should go without saying, but I'll say it anyway, always use appropriate
safety gear when working with any of these chemicals.

Here's a before and after using Easy Off to degrease then an overnight soak in
muriatic acid solution. Yeah, that's right, muriatic acid. It's also a rust remover,
but I don't recommend it's use casually. It get's the job done in short order. Then
a good scotch brite rub down prior to primerr/finish coat.

A note about media blasting. If plastic media blasting is used, the metal needs to
be etched afterwards. This is done to provide adequate adhesion for primer/finish
coat.

Sorry for the gigantic photos. I believe MattNall explained how to right size them,
but I'm old, slow and technology challenged.
