- An accidental experiment leading to a serendipitous discovery.
I left a wrench in Evapo-Rust for 3 years because after about a year, I honestly just forgot about it. Did I accidentally create life? Maybe.

I have contacted CRC (current owners of Evapo-Rust) and the original inventor of Evapo-Rust. I have been running this experiment longer than CRC have owned Evapo-Rust, so they did not know what caused this but "will be looking into it". The original inventor has yet to get back to me. I will keep this pinned post updated if something new develops. More detailed updates will be on Instagram @handtoolrescue.
You had it in a stainless steel bowl. I wouldn’t doubt if some kind of plating happened. Sometimes with brass tools in evaporust it will put a layer or brass on everything.
does it taste any better for maturing for three years?
So CRC purchased Evaporust? Is that why they haven't sponsored your more recent videos?
I did this years ago in a plastic container. Same result. And its still in the solid goo.
Reduced iron oxides frequently make green colors
Hi, corrosion technician here! My guess is the shiny metal is a result of ALL of the oxide layer being removed, leaving perfectly bare, unblemished steel. This of course is normally hard to do, as contact with oxygen starts rusting it again almost immediately. In my industry we call this " active corrosion", but most of us have only read about it happening. The discoloration is where the steel was not entirely encased , thus allowing oxygen to get to the steel. Either that or alienz.
I had the same guess when he said that the dull finish is mill scale/a type of oxide.
Would find it rather remarkable if a chemical were able to distinguish between rust (unwanted oxide) from surface finish (wanted oxide).
But of course aliens is always a possibility. 😉
I would further speculate that the hardness, coarseness, and anti-corrosive nature of the surrounding compound combined with frequent exposure to potential extremes of temperature (e.g. shop heated during working hours in winter, then left to cool at night after closing) might have had a molecular sanding effect on the wrench on top of the oxide layer getting blasted off. The places on the wrench where corrosion built after the fact were either where the wrench physically contacted the stainless steel bowl, or where some fault in the compound extended down to the wrenches surface.
Super neat, though!
With where the dark spots of corrosion are on the wrench, it seems that it could be a (obviously very slow/weak) reaction between the rust remover, the iron, and the metal that the bowl is made of (or its plating).
absolutly right.....
@@ruaine83 I suspected this as well, but looking how the components lay in the bowl it seems that the spots are actually at corners that were not touching the bowl, but were most exposed to air.
This is now, the rarest and most valuable HTR wrench in existence. Everything about it is special. The story, the defect, the 3 years in forbidden liquid nutella worth of newly, mysteriously gathered patina...
"Hi, my name is Ian McCollum and in today's Forgotten Tools video I'm going to show you the rarest prototype of the EvapoCrust Wrench developed by the famous HTR Company of Canada."
Whoa! Could you stop it! I was going to offer to buy it!!! Now you ruined it for me!!!! 😂😂😂😂😂
This is probably the best sales pitch for a rust remover I've ever seen, and it was completely accidental. The fact that the steel is still pristine shows just how gentle it is on the base metal, and that it still works after being redisolved is amazing to me. My brother works in steel fabrication and I'll definitely send this video his way!

Well don't leave metal in vinegar that long would disappear literally
@HandToolRescue What’s really interesting is that when you got a reaction on the black layer with the magnet, it acted like a magnet itself with a North/South polarisation rather than just a piece of iron. It makes me wonder if the microscopic iron particles all aligned in a certain way due to being suspended in solution for such a long period and potentially even aligned with Earth’s magnetic field. It would be fascinating to see if that layer all behaves in a similar way (i.e. has the same North/South polarisation)
Yeah, that’s probably actually what happened, the tiny particles were aligned in suspension either by the earth’s magnetic field, or perhaps some other field nearby, EG wrench may have accidentally become slightly magnetic, and remained so as the solution reduced until there was nothing, leaving it very slight magnetic.
ahah, i was about to write a comment on this black crust, which seems to be magnetite (Fe3O4). Would be a good idea to test it indeed.
@@Nevir202my money is on earth. there wouldn't be any sources of a sufficiently strong 24/7 magnetic field in his shop.
that's how the lode stones formed that the Vikings used as compasses.
molten iron ore slowly solidifying with the iron being aligned by the Earth's field. 🤓👍
Black iron oxide (as used as coating) is just magnetite. Which well, is easily magnetized, which is where its name comes from.
Bingo! Iron atoms have N/S - the earth’s magnetic field aligned them and then ‘froze’ in place during evaporation.
I love the line "I don't understand the shiny."
You need that on a t-shirt, mate.
Hahahaha
@@HandToolRescue I would totally buy that shirt!
@@mohawkman2888 me too!
I was a Chemist in a past life. One old trick to better understand the composition of Evaporust is to contact them for an MSDS. It will contain information on the chemical makeup. Easy to justify since you operate a shop with a 55 gal open drum and are often elbow deep in the stuff.
I’m curious about the chelating agent (used to be my area aka ligands). The most common by far is EDTA and is found in many many products. It could be that or a similar compound. It also sounds like it has a strong reducing agent (the sulfur compounds).
Just remember LEO goes GER - Lose Electrons Oxidation, Gain Electrons Reduction. The shiny surface is likely the removal of an oxide layer.
As for the latter part i am guessing the black oxide finish.
Funny you should say, there's a US SDS and an ISO MSDS public on their website. However they do not declare any ingredients; they merely declare that none of their ingredients are recognised as hazardous material, which is perhaps why they didn't feel they need to declare them. Perhaps you can draw some conclusions from other data in there, if you'd like to take a look.
One of their importers Ströbel publishes its own EU MSDS which reads Water >83%; Non-hazardous chelating agent, proprietary,
@@SianaGearz🧐🤔……… how interesting!!!! Thank You for this insight into how such games are played. ✌️😊
every commercial user (except individuals?) needs to have a paper copy of the SDS (they changed the name for no reason) of every chemical they use in a visible location, so they're extremely easy to find online. the manufacturer can obscure trade secrets and list complex mixes of chemicals under a general name and evap-o-rust does both.
The MSDS is worthless for Evapo-Rust. Makes me so frustrated as I want to know what's in it. They have only ever said it's not EDTA, but a chelating agent, a sulfur compound, and a detergent/antiox. But that could be anything.
Regarding the parts being shiny, I think it is quite possible that the sulphur contained in Evapo-Rust formed a mid sulfuric acid and removed all the mill scale to give you that shiny surface. Sulfuric acid is one of several acids that are used to remove all mill scale from ferrous metal surfaces in preparation for welding. Another thing I noticed which I found rather puzzling was the use of your super magnet to test the solids left from the Evapo-Rust. The one particle that was attracted appeared to be magnetic itself as it kept trying to invert its position which would tend to indicate it was magnetic and had polarity.
With a magnet that strong, it's possible it was causing induced magnetism which might seem to cause polarity. Things are generally either attracted or not attracted, that appeared to be just barely attracted. I'm not sure what to make of that fact tbh
@@skeetsmcgrew3282 It's called paramagnetic, something that only becomes magnetic in the presence of a strong magnetic field. Liquid oxygen on an electromagnet is the cool lab demo usually done to show it.
Mill scale is a form of iron oxide, so its unsurprising that Evap-o-ironoxide removed it from your tool.
Commenting to boost parent comment. Mr. Incredible pointing at the table saying "oxide is oxide!"
Also boosting... rust is rust even if you do call it mill scale :)
My first thought, too.
Same!
I know gun folks have complained about people who use Evaporust on blued steel finishes since it also removes the oxides that make up that finish. So I think this is very likely.
If there's a sulfur compound, it seems like what you'd end up with is largely ferrous sulfide, after all the reduction had happened, if my 10th grade chemistry doesn't fail me entirely. You should send that to NileRed for analysis...he's got a benchtop NMR machine.
Send him some goo! It doesn't even have to cross any international borders! But is it considered a hazardous material?
I've actually sent him some emails before, but he never responded, possibly because he hates Nutella. Maybe if we all email him it can get noticed?
@@HandToolRescue Devious Plan. But it's gotta work, right? Or maybe we can have This Old Tony do a taste test.
everyone spam @NileRed in the comments and ruin his mentions.
If all else fails, send it to AvE to see if old Uncle Bumblef**k can make heads or tails of it.
Based on the color and ferromagnetism, I'm guessing that some of the sludge has turned into Fe2O3 (hematite). Also, that "Stay Negative" shirt is magnificient.
I really enjoy your work and you as a person. You completely take apart and rebuild items, I am amazed at how you know how every little part is to be put.
Eric, the discoloration of the steel wrench parts seem to be at potential contact points with the stainless bowl, and I wonder if some galvanic process took place there over time? Have you cleaned the bowl to the point of seeing any corresponding marks on the bowl? I wonder if there was a very slow transfer of chromium or nickel to the wrench, from the bowl? We must find out!
Hmmmmm, I have not cleaned the bowl out yet, but maybe there is something there...
So, yeah, this seems like a really good possibility. I know with a copper plated item I put in evaporust and forgot about, that there were some galvanic results. I suspect that you pulled some portion of nickel and/or chromium out of the bowl.
spot on, saw a similar thing in a detroit factory way before said dude created rust. i wonder if this caused the owners of the laborers to move all the jay-oh-B~S to a place with virgin labor candidates.
The stainless steel of the bowl contains chromium so maybe there is chrome deposition taking place too.
ITS THE DEBOWL!!!!

This is one of the most interesting videos I’ve seen in a while, coupled with your sense of humor made it even better
I appreciate the selection of grunts provided during the wrench extraction process.
If you have any solid pieces left, I operate several labs with elemental analysis equipment. Be happy to analyze them.
Thank you! I have the whole bowl left! Email me. handtoolrescue@gmail.com
Awesome offer, can't wait for the results
This chap is a hero.
I'm excited to learn the results!
“Never underestimate the power of the Schwartz”
It had to be said!
I hope lab results confirm this substance would have achieved plaid in another light year of being in sublimation!
You actually said the solution to why it is shiny, the coating is an oxide layer, just like rust is an oxide layer, the rust remover removes oxide layers. I recall when I used rust remover last there is a warning that it will remove bluing because that is an oxide layer.
normally when you pull stuff out of evaporust its blackish in color. I used it to clean a bunch of old screwdriver bits and they where black as night after 6 hours. Mind you this was in the stuff for 3 years, so its a wonky amount of time anyways.
yup. blueing something is just rusting it. but in a controlled way so the oxide layer is even and consistent.
Brilliant vlog.
Keep us all posted always been interested in the chemical make up of Evap o rust!
Considering how much Evapo-Rust costs here in the UK, I'm just amazed you had enough that you forgot about a bowl full.
He's got what looks like a 55-gallon drum of it elsewhere in the shop. About $1000, which is pretty reasonable if you're removing rust from lots of parts as part of a job (like this channel). Particularly because of how re-usable it is.
nice pfp
@@PeregrineBF Yes, it's a lot more expensive here in the UK. Or it can be (the price fluctuates). For instance, at present a 55 US gallon drum of it would cost about £1,486.485 or around $1,840.71.

@@somethingsnowing Yes, indeed. They talk about it on FitZall podcast.
So that's why my car is falling apart.

I would like to know why he did this.
Before 1993 we were so much happier without rust in our stuff.
I absolutely love your sense of humor. Great video you did, as usual. Cheers. 😊👋
You’re a very funny chap, loved the struggle with the chair. Btw I’ve been with you since the start, it’s been perilous
We mortals sit in astonishment that HTR has not yet upgraded his chair with utlra-precision bearings or at least a LOT of babbitt. And/or a two-stroke gas engine to rotate effortlessly on the part of the occupant.
If you give the time it took to achieve this finish the modest price of $15 / hr, you could sell this on the store for $394470. Own a rare evapo-crust skinned wrench!
For that price, I’d make my own.
@@BlackSoap361 all of us DIYers end up saying things like that and then take 4 years and $400000 to make our own
Interesting video. It shows evaporust is pretty much safe, no matter how long you leave it in! Also great to hear your voice for free! Please talk more on TH-cam! 😃
A couple of ideas about the green coloration could be nickel leached or chemically reacted from the bowl it is in. Also the black spots on the wrench could be associated with an oxidation-reduction reaction also with the stainless steel bowl. Maybe some one who knows more about chemistry and metallic interactions can figure this out.
This is Awesome. I don't understand what you did except to let these tools sit in a rust solution. They turned out pretty dang cool.
You've done the science that I don't think even the makers of Evaporust have done.
Now... 3 more years!
3 more years in a sealed container

As the inventor of rust, can you reveal your reasons and the backstory?

Chillin' out, waxin', relaxin', all cool
And throwin' some wrenches outside in the pool
Past a couple of days, which was really no good
Wrenches turning red right where they stood
I got one little look and they felt all crusty
I said, "These solid steel wrenches look like they are rusty!"

@@leeroyholloway4277 you win!
About 5years ago I won one of your mini wrenches in a give away and I still use it to this day. Have always loved your videos
After many years of putting it off, I finally ordered a little wrench. I have always loved the design… even printed one out of plastic for fun. Anyway, really enjoy the channel. Even though I am subscribed, this is the first I have seen the channel pop up in my feed in almost a year.
I love the comedy that is your channel! I know there are many out there with restoration videos but I started with you and yours is still the best, funniest, and coolest restorations around. I don't film myself... yet but I restore cast iron pans, axes, blades, shovels, hoes, and other hand farm tools thanks to your inspiration.
Would the black layer have some properties of hematite?
I believe there is this channel, and one dude running 5 others.... there is definitely something fishy about all those German ones.
"Why is it shiny?"
C'mon man. You know that an oxide layer makes steel dull. Your wrench just spent years in a chemical that removes and sequesters oxides.
I think you know why.
Love your channel man.
This is your best video hands down, just based on pure intrigue
Some iron alloys, mostly those that are iron and sulfur tend to either be non magnetic or weakly magnetic like Pyrite. So testing the layers for iron with a magnet may make sense if it uses Sulphur to bond with the iron it may loose that magnetism. I would suggest having each layer tested for iron content. You may be surprised with the green layer as green is one of the colors of certain Iron Oxide compounds.
I filled a motorbike tank ( Yb100 ) of evaporust, after a couple of weeks it looked great inside, most if not all of the rust was gone, I though I will leave it in there until I finish the bike, 2 or 3 months later when I emptied it, it was like a thick silver glue and left volcanic surface all over the inside with a new kind of rust. I managed to seal it in the end with some tank sealant and it was ok but scarred. Evaporust can turn on you !

Bowl of mystery material, found in every college dorm refrigerator across the world.
Great video!
Thank you for the rustful memories. Rust never sleeps.
Looking at it as ya left it in a rust remover solution for years not surprisingly it left bright steel . Steel is not all that reactive over rust in the game over all . Neat reaction to see but not passed what one would expect. Cool things ya did here neat info to us who work to save old iron 😀. Tip hat 🎩 and carry on
You've reinvented the La Brea tar pits.
Might be interesting to see how much the reclaimed wrench weighs compared to others of the same size.
Unfortunately, it was defective in some way so it probably won't be a decent comparison.
The right way to do this would be to mass the wrench before putting it in the evaporust for 3 years, and then after.
all right then, lets head back in time and find out!
Thank you. Short of a time machine, the only way we could REALLY know is to do the experiment again. I would bet cash money the mass difference between "identical wrenches" is on the order of the amount of mass removed from the wrench by the evaporust. That makes it very difficult to use a different wrench to determine how much mass was leached by the original. For instance, this Particular wrench should be heavier than any other he grabs off the shelf, since he highlights the hole for the screw was not drilled out deep enough to close the jaws. That mass is probably more than the amount of evaporust-removed material. If we massed a new wrench and the old wrench we would likely draw the false conclusion that the old wrench GAINED mass from sitting in the evaporust.
had you used that batch or evporust before you left the wrench in for 3 years ? could it bee non ferrous residue from prevous metal . another great video
What is left over (if applied to rusted steel) is: Ferrous sulfide, water (which evaporated in your case), and some salt (ferrous phosphate-assuming you used a phosphoric acid rust remover).
The reason it is so shiny: The steel was, more or less, completely reduced at the surface to expose non-corroded steel, and it was encased in a VERY strong hydrophobic crust (ferrous sulfide-sulfides are always black-that is a dead give away for what the black stuff is). So, water was not able to get to the steel until you removed it from the encasement.
This was the weirdest live birth video I've ever watched. And I've watched a lot of live births.
Same! Do you watch Episiotomy on Netflix?
Geez. I’ve had to watch two first hand. Apparently it’s supposed to be one of the best things you’ll ever witness. I’d honestly rather a stalk had just left a baby on the doorstep. Why you’d want to watch that on TV for pleasure I’ll never know.
The dry heaving! 😂😂❤
Your videos are interesting and informative. You're my favorite Creator on TH-cam! Thanks for the entertainment.
Milscale is a form of oxidation. Thus it was also removed. That’s why it’s shiny. Also parts exposed to air will oxidize again and either rust or go dark colored. Very simple.
When you said you invented Rust in the back seat of Cadillac Coupe de Ville I half expected you to introduce the child you named Rust!!!
Would be interesting to see a similar experiment in a sealed container that would potentially keep it from evaporating so much.
Your subtle humor gets me every time 😂
Super satisfying to listen to the THUNK, CRACK of you finally getting the piece outta the bowl!
I'd be mega interested to find out what the chemical compounds of that black obsidian-like crust contained!
I'm curious if the new "finish" has any rust preventative properties to it? Or does it rust just as fast as the standard mill scale.
It probably will rust faster than mill scale, it doesn't have any sort of passivation layer.
How did you remove the crust? I've got something similar to remove.
Could the corrosion on the part tips be a case of galvanic corrosion? I assume the part touched the metal container on those points.
I use ER in jars in my ultrasonic cleaner, and it will definitely strip black coatings off of bolts. I think it even de-zincs galvanized bolts as well. It's pretty amazing stuff.
What you did not mention was that if you had left the wrench in the solidified rust remover, it would still be there.
But then we would have a Schrodinger's Wrench situation... The wrench would eternally be in a quantum superposition situation...
Comedy and great restorations. Genius!
If you're using a chelator (my guess acetic acid, because its cheap and works) AND sulfur. It's probably some kind of iron sulfide (or a complex of that and the chelator) once it ran out of reagents to react with.
It's non-water soluble, but it's very likely Acid soluble (like hydrochloric acid).
Turned into Hardened Cosmoline
Here are the results of my online research:
1. I strongly suspect that the hard dark green substance is an iron sulphide - i.e. the result of the sulphur in the EvapoRust solution combining with the iron oxide pulled off of the steel by the chelating agent.
2. I believe that the steel is shiny because it was kept from being exposed to the atmospheric oxygen first by the EvapoRust solution and then by the substances dissolved in the soluttion drying into an impermiable crust. IMS things generally emerge from soaking in EvapoRust in a shiny condition.
3. According to what I could find on the internet, iron sulphate is not magnetic. It has something to do with the iron atoms being happy when combined with sulphur, which is not magnetic.
There. I think I have answered your questions.
Wow who knew? Thanks for sharing with us. God bless.
Man, I like that wrench. It looks extremely stout like it would have some longevity to it. That’s 1 thing we want with tools. 👍🏼
A long time ago I read that watered-down sulfured blackstrap molasses can be used to remove rust, with chelation being the method of action. It did work when I used it to derust a spokeshave about 10 years ago.
I think your shiny black magnetic bits are iron (II) sulfide (FeS), just comparing how they look to the Wikipedia entry. The other precipitates would (I think) be some sort of oxide from the other active ingredients in the Evaporust.
That slimy goo that gets stuck to tools left too long in Evaporust is just gross. Found that out the hard way when I remembered a hand plane in a bucket of the stuff that had been in there at least a year.
Man that Evaporust sure did evapo
Oh my God his sweet sweet voice. Haven't heard it since the excellent freebie. I wish I could afford his patreon his narratives are bar none amazing
LMAO!!! "Oh no... ... ..." 😂 beautiful plug!!!!!!! I'm definitely getting some tools now... seriously.
Could you replicate it by heating it at low temp until it evaporated?
Maybe?
A metal wrench in a stainless bowl with a conductive solution. My guess is you set up a galvanic cell. The dark colored spots is where the wrench was touching the bowl. The green color usually means nickel in solution. So you ended up with a nickel plated wrench.
Really enjoyed this. You have a great style to making videos commentated or otherwise
Hahaha I've done a very similar experiment on accident. It goes from clearish liquid, to black liquid, to black liquid with sludge, to a pasty sludge, and then eventually to this end state, though mine didn't get that far since it was in a sealed container.
The petina / finish of the tool looks like some of the 60-70's era tools I have. Maybe it is related to some kind of finishing treatment they used back in the olden days that they abandoned for something faster. This to me seems like something ol Uncle Bumblefuck AvE would have an answer for! I was puzzled by the sediment layers, I would assume the heaviest would end up at the bottom, and that that would be ferrous in nature. But maybe that layer is from the evaporust reacting with the bowl? Is the bowl aluminum? Then you might get some weird reaction with that, a layer of dirt / grime, THEN your ferrous stuff on top as it is leached from the tool? IDK, curiouser and curiouser. Fun stuff tho!
The bowl is stainless steel, so maybe?
I wonder what would happen if you repeated the experiment, but sealed the container so the Evaporust couldn't evaporate?
recently dealt with some parts i had left to derust in a sealed container, so i can speak to this on the scale of months, not years... in my case the solution turned very dark/black, and there was a moderate vacuum seal upon opening the container, so clearly a reaction was continually consuming gases. also, there was a very strong sulfur-y/metallic smell upon opening it
my first guess was oxygen dissolving into solution, reacting with the bare metal, and then being removed by the evaporust. but i'm not very satisfied with that option
on a hunch, i set aside 250mL or so of the dark solution in an uncovered flask, and a couple of weeks later noticed the solution was yellow again, and a thin layer of precipitate had formed at the bottom of the flask (unsure if that was new, or present in the dark solution and took a while to settle out?)
based on this, i now wonder if molecular oxygen plays a role between the chelation and "magic sulfur compound" steps, or if the lack of it disrupts some equilibrium sufficiently to cause the whole reaction to follow a different path? (not a chemist, just hypothesizing with the knowledge and observations i have)
@@v-1nce Good observations -- And fascinating! Moving into my late 70's I truly regret never taking a chemistry course...
Another win for Evapo-Rust! That stuff is incredible!
I am really curious if it's metal, some kind of crystals or which elements they are! Please let me know!
We need AvE to weigh in on this. He knows everything!
Are you going to start producing 1/4 and 1/2 inch nut drivers to round out your third small/medium/large tool line? 😁
Oh my ! More fascinating stuff to follow and yet another site I can’t resist. If only there was more time.
amazing what you found in that bowl there mate top stuff and cheers from Australia 🐨🐑🦘🌏 to your area.
Wait my wrench has a serial number?! *three minutes later* Oh hey, #290, nice.
Damn! The first 500 were hand finished by me.
OK, I want to know how it was left. How long ago did the Evaporust evaporate? Looked like it might have been outside, or at least exposed to dandelion seeds. Do dandelion seeds rust?
I remember that Cadillac!! It was parked on the street since , what, 1939, a fine piece of machinery. Used to pass it on the way to school, admiring it as I did all the spotless, uncorroded vehicles lining the street. Then, one morning in the summer of '93, I was shocked to see the absolute carnage along the same road, overnight most of the Caddy' was sludge, and every car past it incrementally deteriorated. I also remember one young man standing next to it, with a perfectly restored vacuum operated, electrically powered, diesel inclined 1890's nail clipper. Poor bugger looked like he had simultaneously won the Nobel prize, but swallowed it at the same time.
Hey dude, I really love your humor. Cheers from eastern TN
Looks like a little chunk of Resse's Cup.
The forbidden Reese's Peanut Butter Cup.
Out of boredom i did some restoration work on all of the adjustable wrenches at my work. None of them were super rusty.
Is it possible where both ends of the wrench are discolored (rust or whatever) is where it was in direct contact with the metal bowl on each end where the bowl curves upward inside on each end of the wrench? If so, maybe the dissimilar metals touching caused the discoloration. Just a thought
What do you use that huge magnet for? Just general huge magnet things, or do you use it for something specific?
I work in musical instrument repair, and we use that exact magnet with steel balls and barrels for removing dents on hard to reach areas of brass instruments
This is a video I didn't know I needed. I've got a bucket of dried evaporust with a few metal bits in it. Actually it's been dried out even longer than your experiement. Didn't know whether to act like an archeologist and start digging chipping away to retrieve the parts in it, or add water and try to redissolve the evaporust. Wondered if the evaporust was even worth trying to save. After seeing this, it loks like I'll be pouring some water into that bucket and seeing what I can salvage.
And what did you unearth?
@@steadystitch Honestly, nothing yet. I poured about a gallon of water a couple weeks ago and have let it soak. (AKA: I've been too busy and/or lazy to get back around to it. )
I love that evap-o-rust stuff. And yes even in black goo form it Will still work when reconstituted with water, I'm sure deionized is best.
So have we figured out why it will eat magnesium?
I sort of wonder what would happen if the evaporust and tool were in a sealed bag left in the bowl for 3 years, so that none of the volatiles in the Evaporust were to evaporate. Thinking one of those vacume kits for freezing stuffthat seals the bag, most of them have a setting where you can limit what it extracts to the air (and probably a small amount of that wouldn't affect things much) but then seals the bag across the entire opening. Wouldnt surprise me if you had something like that for sealing packages that go into boxes as they head out the door to fulfill orders.
Take away the 'evapo' and you'd just have 'rust' . Did I win?

I repurposed a driveway salt plastic tub for rust removal and forgot some bots and nuts in some rust removal solution that calls itself non toxic and super safe. After a few months i remembered and the metal became a greyish colour with lots of white cloudy stuff in the solution. The bolts and nuts were also much smaller than before and no longer usable :( The difference was my container had a lid that kept the solution liquid, no evaporation happened.
