Quoted from brenna98:WD40 made in Edgerton WI.
I found it works well as a cheap tumbler additive. Keeps the dust down and helps shine up metal parts. I think it works better than flitz.
A company in town (I.K.I.) produces it. Under contract I believe. Along with a bunch of other aerosols and chemicals. My old neighbor is the maintenance guy there. I have quite a few cans lying around that he gave to us. It's handy for some things but doesn't have much use near a pinball machine. As a tumbler additive may be worth trying.
