I've bottled 1000's of beers with my Blichmann Beer Gun. It's awesome! I clean mine by running hot water through it after bottling, then PBW soak for about an hour. Then I sanitize it before use the next time out. Never had a problem with it getting clean. It's a great piece of equipment. You can bottle about 2 1/2 beers a minute if your carbonation levels are right on your beers. Plus, with the CO2 trigger, you can also give it a quick co2 flush just before capping, eliminating any oxygen in your bottle. Highly recommended!
