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!

My first project was to de-rust a part (burner assembly) from an old rusty, abused Coleman lantern. I first used a small wire brush to remove the flaky rust. After soaking for two days, most of the remaining rust had been removed. Another quick application of the wire brush and another overnight soak removed the last of the rust, leaving only shiny metal. The burner assembly was so badly damaged by rust, it was not a candidate for putting back into service, so I left the part soaking for several more days just to see what would happen. Since Evapo-Rust is not acidic, it performed as claimed - meaning it did not affect the remaining intact metal.Before trying this product, I would have used elecectrolysis - which also does a very good job of removing only rust from metal pieces. In comparison, the disadvantage of electrolysis is that it attacks rust by line-of-sight. So, if a rusty surface is not facing an electrode this process will do a poor job of removing the rust. That means nooks, crannies and the insides of tubes and such will also not be affected. -- Evapo-Rust does not have these limitations.Flash Rust (I've seen this when using electrolysis.)After removing surface rust, some steel will quickly develop a very light coat of rust after removing it from the Evapo-Rust. To prevent this, I've read recommendations saying the part should be immediately rinsed and dried after the Evapo-Rust bath, and then sprayed with WD-40, or you can apply a light coat of oil. Another recommendation I read was to spray the metal with a phosphoric acid solution, and let it air dry before painting, if that was the plan. Phosphoric acid is easy to find in hardware stores, sold as a rust remover in spray bottles.Carbon LeechSteel contains carbon and de-rusting can sometimes bring carbon to the surface after treatment, leaving a very thin black surface coating. I have yet to encounter this, but apparently it depends on the carbon content of the steel. If you see this, the recommendation is to use fine steel wool or a wire brush to remove it.A little expensive, but it's re-usable - until it loses its effectiveness. Also, according to other reviews, keep it covered as it will evaporate. So far, I'm very impressed with Evapo-Rust.
