Hey, I am doing a chemistry project on corrosion removal. Most of the metals I am working with are iron and aluminum. I am wondering if anyone knows specific materials, acids, or if anyone has any information that could help me conduct experiments to remove corrosion. Also I would appreciate it if someone would be able to find corrosion removal corporations that I could email for help as well....thanx

Phosphoric acid has been used for a long time to remove corrosion from amongst other things steel. (naval jelly has phosphoric acid in it). The trouble with removing it is that fresh metal is exposed, inviting new corrosion if no coating is applied (after completely rinsing off all the acid)

Believe it or not, Coke works great for removing corrosion. Just soak the metal overnight and brush off the next day. I was able to free a piston in a motorcycle engine by soaking the whole engine block for a couple days. Took a lot of soda, but it did the job.

you could use a wire brush to remove corrosion, but make sure it is made of the same material as the metal you are working with to prevent galvanic corrosion

Coke does a good job for small jobs especiall car batteries. If you have access to acids like nitric HCL and sulfuric work great. When i have to digest metals or clean metal i use a mixture called AQUA REGIA. The mixture is three parts HCL and 1 part Nitric

A nice one for you is a product called ''Naval Jelly''. (It stops rust in a unique way, and I'm not telling you!)
