If there’s one thing that’s bound to happen to every pipe, it will get clogged. Residue build-up can occur for smokers who don’t clean their pipes frequently. It isn’t the end of the pipe's lifespan, though, and there are ways to remove any residue build-up to get your pipe working as good as new. The first step is to separate the bowl from the stem. Dip a pipe cleaner into a solution consisting of water, isopropyl alcohol, and coarse salt before running it through the stem until the residue is removed. Do the same with the bowl. Then, fill the bowl with the same solution and allow it to sit for 10 seconds before pouring it out. Allow both pieces to air dry for 24 hours (due to the amount of time needed for the solution to dry), and your pipe is good to use.
