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