I had questions on how to take care of my glass and I'm happy to find the answers here.
I have some little blades that I find on the street. They come from the street sweepers in this town. I find that these long thin flat blades make perfect little scrapers for preliminary pipe cleaning and resin harvesting.
My wife and I usually wait a while before we clean our bong. I usually take a glass, and attach a coffee filter to it so I can pour out the bong water. I rince all the loose debris and filter it as well. As bud is expensive here, ($40 USD per eighth from one friend, $50 USD an eighth from another,) we often end up going to our resin out of desperation.
Anyhow I usually finish the process on our bong by using hot water, Dawn dish soap and a foam bottle brush. For my smaller parts, I use one of my little blades with a thin strip of green scrubber (the type used on Teflon pans, ect.) carefully wrapped around it.
Scrubbing a bong out this way takes a lot of time and a lot of hot water.
The ISO and salt ways sound waaay faster.
I do have a light encrustation of minerials below the water line. It was at it's worst at the very bottom, but I think that since I started with the bottle brush, it started to break it up. It flaked off at the last cleaning with some help. Now if I use the salt, will it be coarse enough to scrub that junk off?
