ALLEN Foaming Bore Cleaner 12 oz

The Cy-Clean™ Foaming Bore Cleaner breaks down the harshest of fouling and carbon built up without scrubbing. Our Unique foaming action reaches deep down into the metals pores to clean and surfactants suspend the fouling so you can clean it out with a patch. The foam starts out white and will turn blue indicating the presence of copper. Use the included spray tube to direct foam into chamber and barrel, let the foam sit in the barrel for 5-30 minutes depending on level of fouling. After wait time simply remove the remainder of Cy-Clean™ and fouling with a patch.
