Not only does Nucleus offer high-quality glass, but they also have a convenient package made specifically for cleaning these products. The Alcohol and Salt Cleaning Combo includes "IPA Clear" 99% Pure Isopropyl Alcohol and "NaCl" Rock Salt. Pour in a hefty amount of "NaCl" followed by "IPA Clear", plug up the openings, and begin to shake. Pour out the solution then rinse the glass and you will think you have a brand new pipe. Both products included in the Alcohol and Salt Cleaning Combo can be purchased separately but buying them together will save you a couple bucks.
