I was researching how to clean rusty files without damaging them and I think soaking them in vinager is the best option. I have removed rust with vinigar before and it works well, I just curious as to what you guys do. I picked upa assortment 50 Nicleson,simonds and black diamond files for $15 all made in the us and I wanted to clean them up a bit. I bought them with the intention of hammering them out into knives and such but I just cant do it..... they are all made in the U.S.A and quality name brands they range from 5in to 14in metal and wood cutting files. So how do you guys clean them without dulling them ?
