SHTFriday: Putting Rust to Bed

Do you remember that whole mess where my guns got rained on and when I took them out for cleaning they were rusty?  That incident spurred me to investigate methods to remove rust more efficiently than spending hours and hours scouring metal with a cleaner and a brush

Today's Blue Collar Prepping post talks about two of those methods, and they both involve much less effort than scrubbing.  Better living through chemistry!
