One of the best smoking pipe solutions to use is the Orange Chronic cleaner. Use it on any of your metal and glass water pipes that are filled with hard to remove resin.You get almost immediate results since you don't have to scrub. There is also no foul taste or smell when you dump it out.
The Orange Chronic is very easy to use and earth friendly. When you want to use it, shake the bottle and pour the iquid into your water pipe. If you're cleaning your hand pipe, put it in a bag and pour the liquid inside. Shake it in a swirling pattern then dump it out. Pour it out and rinse with water.
