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 ridged 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 that are incorporated into
each and every brush.
Unlike phosphor bronze bristled brushes, our premium
Proof-Positive Nylon Bore Brushes are strongly recommend when using fast acting
copper removing cleaners such as our Eliminator Bore Cleaner or Cu+2 Copper
Remover. This is 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 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
