Trust me, guys. Mouthwash. It doesn't even taste bad, or smell bad. If you have a really tough clog (which we all do) use a big bowl of mouthwash (the shit is cheap, don't be skimpy) and microwave that shit. I'm telling you, mouthwash works like a charm, and you don't have to worry too much about what might remain on the pipe. Mouthwash...
