Got back from the scrap yard about 4 hours ago, been playing with my new keg, chattin with the honey bunny and RDWAHAHB. I got about 50' of 1/2" soft copper tubing. I'm thinking I want to use it for various brewing applications, some where the wort will be on the outside some where the wort will be on the inside. What are some of the more aggressive ways of cleaning it out that I can do in my kitchen? It looks like it hasn't been used but you can never tell. I just want to make sure anything is out. 50' of it was only 8 bucks, couldn't pass it up. If nothing else I'll use it for an Immersion wort chilller or 2.
