So, just to summarize this thread in case folks don't want to read the whole thing, the thread began as a discussion of RezBlock, a retail bong water supplement meant to help keep bong glass clean, made and sold by 420Science (and resold by others). The questions were:
1) Does it work?
2) If it does work, why does it work? and It's very Pricey
3)Is there a cheaper alternative that works as well?
Rather than just a casual discussion, many of the players here were serious about this and used
and the scientific method for a fairly detailed investigation.
Early answers were that it definitely did seem to work and allowed cleaning needing little more than hot water rinses. Several other methods and products were discussed but it seemed clear that the leading contender for ease of use and effectiveness in a bong water additive was RezBlock. It was just kinda expensive.
Then starting around page 16 it was discovered that Cranberry Extract (from Natures Answer) (NACE) seemed to also work extremely well, and was suspiciously similar in many ways to RezBlock, while being WAY cheaper. And not too long after that someone found Botanic Choice Cranberry Extract (BCCE) which was nearly identical to NACE. These products could be had at dramatically lower prices than RezBlock.
@Vitolo was involved in this now and continued the testing, and at some point he brought the RezBlock and the BCCE to a chemist to compare them chemically, and he found that they were identical. While the quantities of the different components within these products (cranberry juice concentrate, vegetable glycerine, citrus acid and purified water) may be slightly different, the components seem to be the same.
I have been a believer since I first started reading this thread, and use BCCE in virtually every glass piece I use with water. It has really made my glass cleaning life easier without breaking the bank. Some people make adjustments like adding more citrus acid to slow bacteria growth, but I find the smell and taste after a day are too much for my post vaping sensitivities anyway so I change my water daily. YMMV
I only mentioned
@Vitolo, but many others including
@t-dub,
@Caligula, and
@pigfoot and
@BigDaddyVapor and others were involved in nailing this baby down. Thanks to all of you.
