Evapo-Rust ER012 Heavy Duty – 128 oz., Rust Remover for Auto Parts, Hardware, Antiques | Rust Removers and Chemicals

This chemical is amazing for removing rust. I had a terrible situation where I had stored chlorine shock packets in my garage, and didn't realize the plastic bags containing the shock powder had degraded to the point that the chlorine was out-gassing in my garage, creating a hyper-oxidizing environment, which subsequently rusted a significant quantity of my hand tools, of which I have an extensive collection. Unfortunately, I had originally thought the issue was due to simple humidity levels, and had INCREASED air circulation in the garage space, serving only to make the problem worse, as it accelerated the spread of the chlorine vapors.This product has been an amazing tool for removing this rust from my hand tools. It's been a fair bit of work, but this stuff really works. No hard work scrubbing or scraping or brushing. Just soak, rinse, protect, and go! The rinse and protect steps are VITAL. I made the mistake of forgetting and letting some batches soak for a couple WEEKS. Don't do that. A black sludge was generated which hardened and was actually hard to remove from the tools. I had to use more of this product to help dissolve this hardened sludge, and it turned those tools a black color. So, don't do THAT. As long as you take them out of the soaking fluid according to the instructions, it works GREAT! And, once you rinse the tools, IMMEDIATELY coat them with your favorite rust preventative. Your tools' original rust preventative, whether chrome or otherwise, is GONE. You MUST apply something new that will adhere well. Paint, oil, or even WD-40. Coat the tools or you will see rust on them again in short order.GREAT PRODUCT! Safe to use! Easy to use if you follow the instructions! Pay attention to the instructions, and I bet you'll see the great results I saw when I used it properly :)

This stuff really works. I had a bunch of tools that were very rusty and to my surprise it worked very well. It tool all the rust off all the tools.This product does not work the fastest but it gets the job done. The only thing is that you will have to soak your items overnight to get the best results.Dont leave your tools in more that 24 hours or else you will get a sludge build up.You also must rinse off your tools thoroughly with water and once it drys spray it with some WD-40 to keep the rust off.Great product

This product is the real deal. I have tried most rust-removing products on the market. I happened to see a review of the product online. The reviewer was skeptical. He was shocked after setting some rusty bolts in the remover for 24 hours. they can be very clean and void of rust. I have many tools that have rust on them. Pliers, aviation snips, chisels, etc. I tried it last night. This morning I took a look at the tools in the remover. They all look next to new. Best of all, when you're done, return the solution back in the bottle and use it again. The photos show before and after. Twelve hours and all the rust is gone!

Used this to clean out a rusty gas tank and it works very well. Just make sure that you have means of quickly drying whatever you are removing the rust from, otherwise flash rust will occur. Best part is that this fluid is reusable and non-hazardous to the environment.

Originally I bought a 3.5 gallon bucket of this stuff to de-rust in the inside of my motorcycle tank. The website says to wash any grease/oil and dirt. off of the parts you're going to soak, but after draining the gas from my tank and letting it sit for a day, I forgot to wash the tank out. I filled the tank with Evapo-rust and let it sit for approximately 24 hours and when I checked it it hadn't done anything.I contacted the manufacturer via their website contact form and received a reply that any amount of gasoline would screw up the Ph and cause evapo-rust not to work properly. So that was around $60 down the drain since it apparently ruins the product. It doesn't mention this in the directions I'd read on the website. This time around I soaked it with dish soap 3 times, rinsing it out 3 or 4 times after each soak. I'll update this review once I see how it works this time.**UPDATE**Ok, so I've had my tank soaking for one week and one day and this stuff is doing the job. It's taking awhile, but one of the reasons I decided to go with this stuff was that it only eats the rust and will not affect the metal. I didn't want to have to babysit my tank through the rust removal processes, so being able to forget about it for a couple of days was ideal for me. I think it probably would have worked faster had I drained the product, rinsed the tank, and replaced the product every day. The instructions tell you you may need to rinse your part and resoak to remove a film that might prevent further penetration into the rust.The instructions indicate that heavy rust might need at least an over night soaking, and while I didn't think mine would be considered "heavy" rust, it certainly wasn't light rust. Now that the rust is pretty much gone, there's pretty decent pitting in the metal in there. I wound up buying another gallon locally (total 3 gallons) because I have no way of telling if all the rust is removed aside from what I can see through the filler hole. I would recommend getting enough of this product that will at least mostly fill your tank to minimize how many different positions you have to leave the tank setting. I really want to find something heavily rusted that I can drop into the solution so I can better see the progress. That and it's a bit of a pain draining it out of the tank, rinsing it out thoroughly, and then pouring the product back in.I also filtered the product through a t-shirt each time I drained it out of the tank to remove the little bits of rust that came out. This stuff definitely does a good job and it's safe to use and won't eat anything but the rust. I wasn't concerned about this because I'm getting a dent fixed and getting it repainted, but it doesn't appear to harm the paint at all. I have spilled this stuff a decent amount though this process and aside from making your hands a little sticky, it's easy to work with. If you're in a hurry this might not be the product for you unless your dealing with really light rust, but if you're like me and want something that you can "set and forget" it will work for you. I waited until winter so I wouldn't have to go without riding my bike for the repairs, so this was a perfect solution for me.
