I know that 10WD40 works great for removing the grime off of handgun and rifle cartridges. So I sprayed my media with the 10WD40 and tumbled a few shells just too see what happens. Like to report that the shells came out nice and shiny and very clean. This will save time as the 10WD40 breaks down the grime alot faster then just the dry media. Give it a try! Please note * Do not over spray the media. Just a lite coat over the top. Thats all you need.
