Cleaning jags are equipped with machined aluminum components that do not react with ammonia-based solvents, unlike brass parts which may. This ensures that blue-green stains, which can be mistakenly identified as false positive indications of copper fouling, are not produced on your patches. Consequently, you can accurately determine when your bore is truly free of copper.
