you know the salt an iso method of cleaning a pipe? id tend to think THAT would do it!

the main idea is that you pour some isopropyl alcohol into the pipe, and then saturate it with salt, and shake. alcohol acts liek a solvent, salt acts like those "scientifically modified microscrubbers!" in your toothpaste(which by the way is called talc, the same shit baby powder is made out of).
