I watched a video on a product called Workshop Hero Metal Rescue. Since I have a few rusty parts I thought I'd try it.
https://www.dimecitycycles.com/blog/workshop-hero-metal-rescue-demonstrationIt is supposed to be sold by Home Depot and Canadian Tire. Neither had it but I did find something which I thought would be similar.


I applied it and wrapped it up like the video suggests for Workshop Hero Metal Rescue.
Before.


During


After. Not exactly earth shattering.


Did the shiny one the old fashioned way .... a minute with the wire wheel on the bench grinder.

Peace & Rust, Dennis
