Rust. If you use electrolysis to remove rust ( water, washing soda, low amp electricity from a trickle charger and a sacrificial bar of iron in a container to submerge the part you wish to derust ) after several hours or days the rust is removed NO METAL
only RUSTED METAL. When finished I pour the water, soda and rust on my lawn ( it likes iron ) CHECK IT OUT it is worth a look. Pete

It's been my experience that all liquid rust removal products are very messy to use and you have to flush them with lots of water. In winter, when many of us work on our projects, this becomes a problem. To me, soda blasting is a good rust removal option because it is dry, doesn't require rinsing and doesn't heat and potentially warp sheet metal like sand blasting does when too much pressure is applied.

RUST can be removed using a process know as electrolysis. Google it. I have had very good luck using this. Safe, cheap, environmentally friendly. Good luck, Pete 

Do you know the product name? Thanks
