Even with the best cleaning solutions, some bits of your glass need a physical scrub. Narrow downstems, slide bowl holes, vaporiser cooling channels — they're too small for bottle brushes and too awkward for cloths. This is where Randys pipe cleaners come in, and they're far better than the craft store alternatives.
Built Different
Standard craft pipe cleaners are too soft and leave fibres everywhere. Randys are constructed with stiff, dense bristles wrapped around a flexible wire core. They're rigid enough to scrape carbon deposits off glass but won't scratch borosilicate or quartz. The wire core bends around percolator chambers and into tight corners that you simply can't reach any other way.
The Best Technique
For best results, soak your downstem or bowl in isopropyl alcohol for 30 minutes first, then use a Randys cleaner to scrub away the softened resin. The bristles reach into slide bowl holes and percolator slits that are impossible to clean with cloths or standard brushes. 120 for £4.99 — keep a pack in your cleaning kit and your pieces will thank you.
