We have just released a brand new cleaner called Kleen, we believe it to be the most effective soaker glass pipe cleaner on the market. Our cleaner was developed as a soaker for today’s more intricate and multi-chamber pipes. Kleen works very effectively on tar, oil, grease, grime, smoke film, fingerprints, and water spots. Kleen is a non-toxic, alcohol free, abrasive free product and doesn't require scrubbing or agitation of the item being cleaned. Kleen is an economical product and can be reused over and over.
