Randy’s Black Label Brushes

Randy’s Black Label Brushes are a three-piece nylon and galvanized steel brush set for cleaning large water pipes, hand pipes, and vaporizers. The set includes three widths — 3/16", 1/4", and 3/8" — each on a 7" handle, providing the length needed to reach through standard bong necks and into chambers where swabs and wipes can not go. Nylon bristles scrub effectively without scratching glass or acrylic surfaces.

Use with any cleaning solution or plain hot water. For stubborn resin, soak the piece first, then run the appropriate brush width through the downstem, neck, or chamber to agitate remaining residue before the final rinse. The galvanized steel handles resist corrosion from repeated contact with cleaning solutions and water.

FAQs

• Which brush fits a standard 14mm downstem? The 3/16" or 1/4" brush typically fits 14mm downstem interiors. The 3/8" is better for wider chambers and tube necks.
• Are the bristles safe on glass? Yes — nylon bristles are non-abrasive on borosilicate glass and acrylic at normal cleaning pressure.
• Can these handle vaporizer cleaning? Yes — the narrower brushes work well for cleaning vaporizer airways and mouthpiece stems.
• Do I need cleaning solution? Not required, but a soak in any cleaning solution first loosens resin and improves brush effectiveness significantly.
