Considerations & Trade-offs

  • This is a dedicated copper-removing solvent, so it addresses copper fouling rather than serving as a general all-purpose gun cleaner.
  • The 6 oz pump-spray format is convenient for application, but it may not suit users who prefer aerosol, squeeze-bottle, or patch-only cleaners.
  • The formula is described as odor-free and free of petroleum and ammonia, which is a practical trade-off if you want to avoid harsher solvent types.
  • The long description notes that it leaves a thin film, so users may want to account for that in their normal cleaning and storage routine.
