The KleenBore Kwik Kleen One Pull Rope Cleaner is ideal for fast and easy cleaning. It is designed with a series of builtin bristles that combines all the cleaning processes into one simple step effectively cleaning your bore in a single pass. The initial floss area brushes the action then removes loose grit and debris in the bore prior to the main scrubbing. Its main floss safely superscrubs the bore to a mirrorlike finish within 160 times more floss than a standard cleaning patch.
