Cleaners & Cleaning Supplies - Brebbia Stem Polish (7.5 ml)
Well it works, kind of. It's very pricey and I've gotten better results with inexpensive solutions that I've put together from safe non-toxic items i have in the house. Only recommended for those who have no other solution to nasty oxidised Vulcanite pipe stems. Perhaps if paired with the more pricey Obsidian oil it may be more effective.
