Testing a Home-made Rust Remover Solution

Thanks to Wood by Wright's video, I came across this home-makeable rust removal solution, which came from a ballistic channel. I thought I'd give it a try and I'm pretty happy with how the results came out, so if you're after a rust removal solution, you should give it a try!
