I use spoons almost exclusively, I know many retired commercial fishermen who give me old gear. Yesterday one of them gave me 3 dozen P2B spoons from 1978 which I love to death been using them for years, now I have a good supply (sorry won't be selling them).
I also teach metalwork and know a few tricks if you want to clean up crusty spoons, do this: Mix 1/3 salt, 1/3 flour and 1/3 Cleaning vinegar into a paste, coat each lure with the paste, put each lure in its own separate ziplock bag and let sit for 24 hours, come back and wash it off, it will be almost clean with little to no elbow grease needed to clean it up. I hit them with some ultrafine steel wool right after and they are perfect.
