Bore Tech Nylon Brush 3 Pack Bore Tech’s Proof-Positive Nylon Bore Brushes eliminate the false indication of copper fouling found with traditional bronze brushes and copper removing cleaners. With twice the amount of oversized bristles, double wound cores, looped ends, and barrel safe studs, these brushes are exceptionally rugged and provide safe and effective scrubbing action—all while setting the standard for nylon brushes. Bore Tech’s Proof-Positive Nylon Bore Brushes are 100% barrel safe and set the benchmark for all other nylon brushes. This is due to the superior construction and engineered features incorporated into each brush. Unlike phosphor bronze bristled brushes, our premium Proof-Positive Nylon Bore Brushes are strongly recommended when using fast-acting copper removing cleaners such as our Eliminator Bore Cleaner or Cu 2 Copper Remover. Traditional phosphor bronze brushes contain over 90% copper in their composition and will turn patches blue when in contact with most copper removing cleaners. With barrel safe, non-brass cores and threads, Bore Tech’s Proof-Positive Nylon Bore Brushes are not affected by copper removing cleaners and will eliminate blue patches and the false indication of copper fouling that is associated with traditional phosphor bronze brushes.
