Adam Savage's Favorite Tools: Safe Rust Remover!
Evapo-Rust Rust Remover: https://amzn.to/3w8uCDW
Adam has recently been obsessed with watching restoration videos online, and there’s something used in all of those videos that he absolutely loves: Evapo-Rust rust remover. Adam is a fan of how safe and effective it is to use, and how it can be reused over and over again too. Here’s how it works on two pieces of rusted parts from the Tested studio and around the cave.

much, much cheaper and as effective:
Per litre of water;
1: 100grams Citric Acid.
2: 40 grams Sodium Carbonate (washing soda) OR 63 Grams Sodium Bicarbonate OR 30 grams Sodium Hydroxide.
After reaction has completed, add final ingredient.
3: Arbitrary amount of liquid dish soap.
The last item I freed up was a thin-mouth monkey wrench I had had from my scuba diving days, and loved. Not loved enough to forget where I left it outside one time. 4 years later found it again, a rust ball. Left it a few days in the homemade solution and was able to extract the screw and free up the mouth, then another day in the dip and it works like new. Not as pretty, as the steel that gets eaten by the rust does not come back, so there is some pitting, but only cosmetic.
And the above solution is as about acidic as tomato juice. But I wouldn’t make a bloody mary with it.
The ONLY caveat is that it does remove any thin galvanised layer that might have been remaining, but if there’s rust, it probably wasn’t galvanised so well anyway.
Give it a try, it’s also reusable, and cost pennies per litre, and the ingredients can be got from the local supermarket (the acid and bicarb can go in cakes too, if you are feeling fancy 🙂 )
Evaporust is magic. If you have more time than money, especially for really big parts, soak part in 1 part molasses dissolved into 9 parts water (like in a trash can) for a few weeks (works faster in summer). Old hot rodder trick. Natural chelators in the molasses remove even heavy rust.
You got me laughing saying about that big rusty spring, let’s see what it can do.
I’m surprised you are not using this or acidic or otherwise solutions in an ultrasonic bath , they have become really cheap and speed up the process tenfold they sort of introduce the "scrubbing" action that you mentioned.
CRC have released a spray on gel version of this product Evapo Rust in Australia which is mostly Phosphoric acid in a gel formula. The product is totally useless. It might seem that the part has to be fully submerged for some time. The gel tends to dry out too fast on the surface of the metal for it to actually do anything. I have yet to try the liquid version. The other difference is you can’t get the spray on gel version on your skin or it burns.
Somewhat reusable. You will notice a dramatic dropoff in effectiveness over a relatively short period of time for extremely rusty parts. It depends on the amount of rust and size of the parts. If I recall correctly, a gallon of Evaporust can remove something like 8 ounces of rust before it stops working. The liquid will darken to a deep rusty black.
So, for mildly rusted parts, you may be able to reuse it a dozen times or more. Heavily rusted, a handful of times if you’re lucky. I just removed rust on a couple hundred fasteners and small brackets from a 60s Vette. That took an entire gallon over several days. Here are some tips to get the most out of Evaporust:
1. Use a heated ultrasonic cleaner. Harbor Freight sells an inexpensive one and it’s worth it. Set temp no higher than 50C (about 125F), but I do recommend using the max of 50C. Set the timer to 30mins.
2. To minimize the amount of Evaporust needed, I place the small parts into a gallon size freezer ziplock. They’re nice thick plastic bags. Then I fill to nearly cover the parts. Now fill your ultrasonic cleaner 1/2-3/4 the way with water. Place the sealed bag into the water. The surrounding water will squeeze the bag such that the level of Evapo inside the bag rises and fully covers the parts.
3. Depending on how rusty the parts are, you may want to use 2-4 30 minute cycles. Afterward, remove the parts from the bag and inspect them. You’ll notice that you can use a brush to remove light rust, and a flathead screwdriver to scrape off larger flakes to expose any underlying rust.
4. Transfer those parts to a second freezer bag containing fresh Evaporust. Put unprocessed rusty parts into the first bag of dirty Evapo. Submerge both bags in the ultrasonic. Basically, the dirtier Evapo will take off the initial crud, and the cleaner Evapo will take care of any lighter rust remaining.
5. Let those batches sit overnight in the ultrasonic. You don’t need to run the vibes all night, but I do recommend leaving the heat on.
6. From this point forward you’ll be using the same transfer between bags for future batches. As the dirtiest bag of Evapo becomes ineffective, dump its contents into a sink. Transfer the cleaner Evapo to that bag. then pour fresh Evapo in the 2nd bag.
In anywhere from 4-10 hours total, you’ll have parts that, in many cases, look virtually brand new. I’ve used the process above to completely clean various engine and suspension brackets, fasteners, etc.
Then I use ZRC cold galvanizing paint on the bolts to give them a protective layer before putting them back into service. Once everything is installed on the vehicle, I use brush-on Cosmoline on all of the painted and unpainted metal surfaces as a final layer of protection to keep everything looking good for years. Spray-on cosmo may seem more convenient, but it gets all over everything and trust me when I say you dont want that. Just brush it on.
White vinegar will do as good as this or better try it
If you want it to get perfect without scrubbing soak it for 24hrs then have an ultrasonic cleaner with industrial grade simple green standing by…if it heats it works better…fyi the evaporust will remove nitride finishes on gun parts….but I will drop it in the ultrasonic for like an hour after soaking and it looks basically brand new….😁👍
Use gloves, forgodsake man!

Technically rust is a color. What is happening is corrosion.
Any metal parts that have a tendency of rusting or corroding, I have found that Fluid Film is one of the best products out there. Also, I have had great success with Loctite Naval Jelly rust remover.
What do you recommend to use on rusted electronics? Inside my digital torque wrench where the batteries go, it is rusted, not corroded. Every video I see is of people cleaning battery corrosion but I can’t find any of rust removal. Thanks
Try filling your ultrasonic cleaner with evapo rust and heating it. Works much better
How about using the stuff in a sonic cleaner tank?
could I spray this on some boiler fittings? the dielectric unions?
There’s a DIY concoction that’s wayyyyyyyy better than evaporust at a fraction of the price.
So, once you’re done using it, is it really safe to just pour down the drain? How do you dispose of Evapo-rust-o, yo?
I have tried this and several different ones. Also electrolysis, phosphoric acid, vinegar etc.
But what I am now using is perhaps the simplest and I am amazed that it works so well. It was described on a Youtube channel as well that I can not recall now. It is simply a citric acid solution in water that is neutralized with soda + some drops of dishwasher detergent or some ethanol for wetting. Experiment with concentrations for best results.
It is essentially just a sodium citrate solution, I do not know why it works so well. The solution keeps fairly well, but it is so cheap and easy to make that I usually do not bother. Citric can be prone to mold growth, I have seen this in some buffer solutions I made.
You can also use 1 liter water, 100 grams citric acid and 62 grams baking soda with a little dish soap. Mix in a large container, it will react heavily then pour it in a jar or spray. Cheers
How about electrolysis? I have an old battery charger dedicated for this use. I restore old rusty cast iron pots and pans, and they come out like new, freshly cast items. The cost is very close to Zero.
You should do a comparison with CLR
Can you try
Nexa rust remover?
I like Evapo-rust rover safety and that it is reusable. Thank You
Vinegar works well to soak tools 24 hours
have you tried vinegar?
This sounds like sponsored content to me. Evapo rust is ok for some things, but its overpriced and isn’t all that that reusable. .
I wonder if it would work better using that product with things like that spring in a tumbler?
Home made one that beats Evaporust.

Does anyone know if this will work with my shotgun parts?
Has anyone used the gel version yet? Does it work as well?
Sorry Norm!
Cheap and easy way to remove rust: 2 tablespoons citric acid and 150 ml of hydrogen peroxide. Mix well. Fully submerge your tools.
It takes a little while to start reacting. It does generate a fair amount of heat while the reaction is happening. You can do this in a cheap plastic cup without a problem.
I have not tried mixing any larger quantities so i can’t guarantee the heat produced or if your container will handle it. Use caution and do this outside for larger objects. Its going to get hot.
This is good but not as good as the DIY rust remover.
Sorry but that spring still doesn’t look very good even after three days
Regular white vinegar from walmart, soak parts for a few days, scrub clean in kitchen sink. Just luke new for 2 bucks a gallon
It should be noted that if you have a rusted panel like on a car you’re restoring and the rust has eaten away at that panel affecting it’s structural integrity then NO rust removal method is going to make any difference.
Deox-C from Bilt Hamber.
Most comparisons say it is better than Evaporust.
I would love to spend a few weeks Holiday in that Workshop 🤩 I’d even sleep there 😴. Imagine the amazing things you could build!
I’ve had the 5 gallon bucket of Evaporust for a couple of years now… It was expensive but has been worth the money as I just toss stuff into the included basket and let it sit overnight. Way easier than messing with bags, and virtually none of the product is wasted. Highly recommended if you deal with rusty items regularly.

I havw a smALL WOODBURNER with completely rusted door hinges I can soak them so how can i fix this problem?
LOL. This guy needs a real job.
it didn’t work on the spring ? snake oil, waste of time and money ?
Evaporust is overrated and overpriced. Beyond Ballistics (2nd channel of Backyard Ballistics) has video of a more effective, safe rust remover based off common household products (citric acid, sodium bicarbonate, dish soap) that costs a tenth of what evaporust does. I’ve made myself 10L of the solution for about 10e, the same as Evaporust would have cost me 100e and lasted half as long. Evaporust is 90% branding.
Strange ive used evaporust many times and I’ve had the same exact results as you just did, hit and miss….
Must have something to do with the type of steel the rust is on.
Thanks Dad
Looks like stop bath…. Vinegar? What’s the pH? I have some pliers, diagonal cutters, linseman pliers that need to be revived.
I used to watch restoration videos until I found out that many of the things that they were restoring were artificially rusted and battered to begin with. Gave up then.
When you’re paid to endorse a product but it doesn’t work as well as vinegar lol
I would use a wire brush to remove the rest of the rust. I use evaporust frequently, but you need to help it release.
