Just like the formation of rust, industrial rust remover acids use chemical processes to remove rust. So what does this mean for industrial rust removal? Understanding what causes rust can help to understand how to get rid of it, and which methods work better than others, and why. Other non-ferrous metals like aluminum, copper or lead, can corrode, but they don’t actually rust. However, rust is specific to metals containing iron, which includes all types of iron (wrought iron, cast iron) and steel (carbon steel, stainless steel). Oxidation is one type of corrosion that can occur on metals, and many metals suffer from oxidation. Salt water in coastal regions or from winter road salt, as well as acid rain in some urban or industrial areas, are known contributors that speed up oxidation. When oxygen, water, and iron meet, a subtle and invisible chemical process occurs that causes electrons to move and turns iron into iron oxide, also known as rust. Rust occurs when iron and other ferrous (containing iron) metals oxidize. In this post, we’ll explain how different types of industrial rust removal acids and water-based solutions work, so you can find the best product for your needs. There’s not enough time in the day to sand and scrub rust off, but you still need your metal parts and machinery in top shape. Rust can ruin the metal parts you need, cause machinery to malfunction, and create safety hazards. Fastest way to clean out the rust you could come by.If you work with iron or steel parts or equipment, you’ve almost certainly had to deal with rust. If need be, it would probably work fantastic on cleaning up an old rusty bed if it held water, and you dumped a couple of 5 gallon buckets in there and brushed around. I don't think I would use if for painting a deuce though. I've bought the nastiest pipe wrenches and cresent wrenches from GL, put them in a 5 gallon bucket with 2 cups of white vinegar and filled with water and tools, brushed them off 15 minutes later, then another cycle of it, dipped in oil after rinse and dry, and a year later not a sign of rust on these looking like new tools. Plan and schedule your effort well and do it right and you will not have any problems. If you don't paint or prime it within 24 hours, it will start to turn orangy again. The most important thing about vinegar is, you must rinse it off thourally, then paint the next day, or prime, if you can do so. It will take it down to bare metal in most instances, EXCEPT where paint has been applied over it to seal in the rust. ![]() Even a medium nylon bristle brush will do. ![]() It need sit on the metal for about 15 minutes, then wire brush off. It will mosty just run off on vertical surfaces, and not cling long enough to do the job I desire. I use white vinegar on all my tools and rusty metals that are portable and I can lay down horizontally. In the instructions on the back of the container, it reads "Safely Dissolves Bleeding Rust From Many Painted Surfaces". I think that if they were scrubbed with a stiff bristle brush and hosed off, they would look the same as the inside ones. The scrap pieces have been stored outside with no protection and they look about the same except that they have acquired a layer of dirt. ![]() They look as slick as the day I installed them ten years ago. Most of the beams were used inside for a wall stabilization project. All of the steel turned a grey/black color with the rust spots being darker than the clean steel. Some of the steel that I treated was ground down to shiny clean surface and some was left rusty. It is somewhat expensive, but I did 20 4in I-Beams (20 feet long) with less than a quarter gallon. The company that produces it is the Skybryte company in Cleveland Ohio. I acquired it from a marine/boat product catalog whose name escapes me. I have used a product called OSPHO (contains phosphoric acid) to treat raw steel.
