Description
The Bore Tech Nylon Brush is a three pack of 100% barrel safe nylon brushes. Bore Tech’s Proof-Positive nylon brushes are recommended when using fast acting copper removing cleaners, due to the fact that 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 these barrel safe, non-brass cores and threads, copper removing cleaners wont react when in contact with copper removing cleaners.
