Soaked in a well used gallon for 2 days, got better but not clean.
Bought a new gallon and bam a few hours and it's sparkling .

Some folks say vinegar does the same thing cheaper. Never tried it myself. Anybody else tried?
Vinegar is an acid and it removes metal, evaporust is not an acid and only removes the iron oxide.

I wonder what that cost him.
A little over $10,000.00 buying it in 55 gal. drums! Plus shipping and tax.
I think that evaporust has some kind of acid in the formulation.
Evapo-Rust Patent #03510432A NONCORROSIVE RUST REMOVER Albert T. Squire
Quote Example 1:
Water 4000 gm. Ammonium citrate 200 gm. Sodium phosphate 40 gm. Sulfuric acid 17 ml. Surfactant (SLS) sodium lauryl sulfate, etc Preservative Agent (sodium benzoate, etc) as anti-mold
In that process of Chelating, there is a "Sulfur" bearing organic molecule.. That is the sulfuric acid part of the solution. The PH is so mild that it's not aggressive towards the steel, just the iron oxide part of the piece.

I bought my blast cabinet 35 years ago. I don't know how I ever did without it. Given the price of Evaporust, I'd guess the cabinet has save me a lot of money over the years. No acid in the sand, either. Just my humble opinion.
If it's a concern, glass beads are much less aggressive than sand.
I think I used sand on this steering box. Looks good to me. (And, of course, the bearing was installed after the housing was clean.)

Steering box is aluminum so evaporust would do nothing to it.
Well, there you go then.
I think you have one too many zeros in that price.

He probably meant the total 2,000 liters used for that video. I'm pretty sure he didn't pay a dime thought.

More seriously, I was responding to the suggestion that blasting can be too aggressive. Professional sand blast equipment and high powered compressors, yes. My blast cabinet and its 5 hp single stage compressor, no. But I once made the mistake of using a really powerful sand blaster on a hood. Warped the crap out of it. Wouldn't do that again.
Okay, I read that a little wrong. It just needs to stay wet. Recirculating it with a pump would save the usage amount.
I've tried it all, evaporust, Rust911 which I think works just as well and just as expensive. But seems to last longer. White Vinegar, but I like Citric Acid the best. .
I with @RustyRatRod on this. Evaporust looses it's potency to quick

It sure seems to with me!
I’m not sure about evaporust, but molasses does work. I did a V8 with it, did it one side at a time with the deck facing up on an engine stand. Taped up the water holes on the front and the deck facing down. Worked well.
2000 liters = 528 gal. = 10 - 55 gal drums at $1022. per drum fom Jegs.
Hey Dana , a little side by side test of Citric Acid VS Evaporust
Like 50 cents worth of Citric Acid and whatever 1/2 gallon of Evaporust cost nowadays.
Same condition when dunked for about 4hours.
I really see no difference in them.

Evaporust is about $20+/gallon. Thanks for comparison.
