Iosso’s Non-Lethal Launcher Cleaning Kit contains a one-piece brush on a stiff wire handle, six premium 6-inch patches and a bottle of Triple Action Oil cleaner. The brush is made of a durable phosphor bronze material and fits 37mm or 40mm bores with a 15-inch usable length. The patches are 100% cotton knit, which will not shed. Iosso Triple Action Oil is a bio-based penetrating oil that cuts through tough plastic residue and fouling associated with the non-lethal cartridges. It is economical and easy to use. Proudly made in the USA, it emits no odor and brushes are available for sale separately in bulk. MSRP: $34.95. Contact: www.iosso.com
