I’ve become a fan of these ‘Zen’ brand pipe cleaners.
Pipe cleaners have become something just handy to keep around the house. Sure, I use them for cleaning pipes — but carburetors, fermentation airlocks, and children’s art projects all benefit by having them around.
These have harder bristles and do not shed as much as the softer variants I had been using. The lower shed factor has made them useful for cleaning vaporizers as well as glassware. I just dip them in Formula 420 and scrub away.
Clean pipes taste better and, while I am sure it is imaginary, I think I get more stoned.
