Real Avid ZipMax CLP is a potent, non-smelling solvent that will keep your firearms in top-notch condition. Real Avid CLP can be used to remove fouling caused by the build up of copper, lead, powder, black powder, rust, and more. While this CLP is a very effective cleaning agent, it also has another very unique attribute: it has absolutely no smell. With no obnoxious fumes to deal with, cleaning your firearms will be a much more enjoyable task. Real Avid designed ZipMax CLP to penetrate up to four microns deep into the firearm's bore for a lasting, deep clean, and it seasons the barrel over time to make your weapon easier to clean in the future.
