Review on Aviditi VCI1235 Paper Industrial Roll by Brian Kingsford

My knife expert and collection curator used it on a collection of very expensive knives and within 24 hours ALL the brass went from bright and shiny to tinted, which took 30 minutes or more for each of the 50+ knives to be cleaned up. The stainless steel and steel blades also began to stain and needed a thorough cleaning. Not sure how it would be with firearms etc. But very surprised that it is better to lubricate blades etc and leave them in zipped bags. Any help is welcome. HKM Family Member / Gold Star / Nam Era Vet
