I had some traps that I got for Christmas last year and just cleaned and set. Well after 10 months they started rusting pretty good. I had read that vinegar and water would remove the rust, so I mixed a couple of gallons of vinegar and a couple of gallons of water in a five gallon bucket. I left the traps in for two days and pulled them out this evening. I now have shiny brand new looking traps again! Some of them were really rusty and it ate it all off. Hope the integrity wasn’t compromised, set a few and they still fire just as fast as I remember. The 3lb hammer still sets them off when the hand starts to release the handle. I was really impressed!
