Hi all. Newbie here. My folks have passed and I'm going through my dads garage and sheds. He has a TREMENDOUS amount of tools and parts and screws and nuts. I have no idea what a lot of this stuff is. Not sure if I should I try and save them or take to scrap. Right now I have 3 tubs of rusty nails and screws. I'd like to try and save them. I plan on building a green house and a bigger chicken coop. I was told I could make a lye bath. How exactly does that work. And how would I keep the nails from getting rusty again. Here is a picture of the nails and screws in question. (And this is just the teeny tiny tip of the iceberg.)
