Evapo-Rust vs. Rustoleum Rust Dissolver

[Old Henry]

Just did this experiment de-rusting part of two very rusted tin snips. One with Evapo-Rust, the other with the relatively new Rustoleum Rust Dissolver. I was wondering what the difference might be since the Rustoleum is cheaper. I wondered if it did just as well as the more expensive Evapo-Rust. Left is the one in Evapo-Rust. Right is the one in Rustoleum.



They both removed the rust equally well. But, the Rustoleum seemed to keep "sizzling" after the job was done, almost like it had some kind of acid in it, and left the metal coated with some black coating like it was carbon coated, whereas, as is shown in the photo, the Evapo-Rust cleaned off the rust but left the metal clean and metal looking if not actually shiny.


At Walmart, a quart of Evapo-Rust is $9.36 whereas the Rustoleum is $7.82 for the same amount. I'll stick with the Evapo-Rust myself. I think it's worth the extra money.
