To a headshop and buy Formula 420. I admit, there are better (cheaper) ways to clean a pipe... but that stuff will at least show you HOW clean you can get your pipe. I didn't clean one of my bowls for a couple of years. I bought some of that stuff and in about 10 minutes I saw what the pipe looked like when I first bought it! :thumbsup:

You can also get a feel for the consistency and ingredients of Formula 420 and then make it yourself with some alcohol, salt, and citrus juice.

Have fun and Happy Cleaning :jointsmile:
