Evapo-Rust The Original Heavy Duty Rust Remover, Water-based, 5 Gallons

Wow! Unbelievable! I wanted to try and salvage some 30 year old chain binders and chains. They were non-functional from all the rust. After just a few hours of soaking all the rust was gone. I sprayed the crc-36 on them and they work like new. Just incredible!

Great product for getting rid of rust. Restoring a 1978 Bronco and this stuff is making my job easier. The parts come out like new saving me lots of time. Works great!

I have used this over many years. Great stuff works fast. I have noticed some complaints that it doesnt work as well. When I first bought it years ago, I had some difficulty. It worked good, but the material would lose its effectiveness. I experimented....Now it works amazingly. First, make sure your part is free of all oils and grease. oils and grease will contaminate the fluid. Secondly use a secondary container. No need to contaminate the entire bucket for some small parts. Use a left over yogurt container or bowl or something like that and pour the fluid into it. Cover the container so the fluid does not evaporate. The fluid will last a long time. Do not pour the remainder back in the bucket. Do not contaminate the bucket. The last time I purchased was 5 years ago and that was two 3.5 gallons buckets....and I just recently ran out of it. Also, I agree that I miss the pour spout from the 3.5 gallon version. Luckily I kept my 3.5 gallon containers so I transferred the lid with the spout to the 5 gallon container. Plus I use the 3.5 gallon container with the strainer for larger parts. Again, make sure that parts of free of oil and grease, and use separate container to de-rust. And finally, dont put used fluid back in the virgin fluid. Happy de-rusting

When i worked at volvo corporate, the division that i was at had a good 100 liter pail that was filled with this fluid.if any parts were lighly to extremely rusty but was sensitive to strong solvents or blasting we would dunk it into the evaporust, leave it for a day or 2, and then come back, wash it with water, dry it with a rag/air (depending on the part), and clean with a dremel, it would leave them like new.As i am no longer in that industry, i got this bucket and follow a similar procedure (dunk ,leave (1-2 days), clean with water,dry with rag or air, clean with grinder brush/dremel brush, coat with wd 40).this fluid is not toxic and washes off easily (water washes it off), ill leave some pictures of items i applied evaporust to. KEEP IN MIND: this for mild/ intermediate rust, if the part is rusted heavily, it will work but pitting will be left as a result of the rust eating through the part, if its heavy rust on a really thin metal, evaporust will pretty much dissolve the whole part.

This stuff is nothing short of Awesome!!!! If you are lazy or don't have time to spend hours sanding off rust, this is your answer. I have written maybe 3 reviews my entire life and this stuff is worthy of a review!!! I use it for removing the rust off old weights from bench press sets, works like a charm. Only thing is it takes time, don't think you will take off 20yrs of rust in two minutes, give it 12-24hrs (depends on how bad the rust) and it will come out looking like new! I buy the 5gallon size and boy do I need it, it says you can reuse it over and over but each time you use it, you will notice it takes a little longer to work, after about three heavy uses (massive rusted parts filled to the top of the bucket) it slows down significantly and the product at least in my instance turns black (probably from the paint on the weights i suspect) As far as paint is concerned yes it kinda takes it off a little?? but its seriously is hard to tell because there is so much rust on these weights thats I'm not sure how much black paint was initially there to begin with. It seems to really just attack the rust. Oh and its seems ridiculously safe very low oder but i will say it kinda has a very faint sulfur (rotten egg) smell but like i said very faint and hardly noticeable (also one of the weights got away from me and splashed in the bucket and this stuff went everywhere including my face and nothing at all happen just wiped it of and went on about my business). Yellowish, like a crappy beer, in color. Also whats great about this stuff is you can just leave you project in there as long as you want 2, 3 even 4 days no adverse effects once the rust is removed it just will sit there waiting for your next project, and it will leave the unrusted bare metal alone. Do yourself a favor and buy big!!! If your like me you will start to find tons of metal tools and the like around the house that have rust on it. PS you will need to dunk, at least the rusted area, and leave it submerged, for a significant amount of time so this stuff is NOT good for tables and chairs and the very large objects.

I don't know what voodoo is in this bucket. Honestly, it's so effective, I'm afraid to ask. I'm not afraid because maybe it's ground up puppies or the crumbled hopes and dreams of a generation, no. No, I'm afraid that--believing that this liquid is actually magic, knowing how it works will break the spell. I've had the same $100 bucket for 4 years. An overnight soak in Evapo-Rust turns even the most rusted clump of a tool that I left out in the rain (or many rains) into beautiful, new-looking steel. It has a weird smell; not overtly chemical or biological. Not caustic or bacterial or fungal. Not bad, just weird, which continues to lend to my theory of its magic--or possible otherworldliness. At any rate, whatever it's made of, it's astoundingly effective. As I said, for 4 years, many tools and found items have spent the night in the bucket, and come out cleaner than Andy Dufresne.

Works pretty well. Cut my blast time in half. Only wish it came with a basket. So took away one star.

Great stuff, the best of rust removal solutions. Unbeatable Price. Will buy again and again.
