Welding Tips and Tricks

Does anyone know if perhaps this works inside a MIG, or do the oils cause issues with the weld, or the machine? Welding wire rusted inside my machine last year due to humidity levels in the garage.

i would not use anything on welding wire. just take it out and store it in a nice warm dry location. i have the same issues.
camphor can be toxic and it absorbs through the skin. not a good thing to be putting on tools at all. i don't think that guy is being anyone's friend. its an ingredient in some of the varroa mite treatments.
