I recently upgraded to doing full boils, and after it taking 2 hours to cool down my last 5 gallon batch, i knew i needed to get a chiller. So after reading lots of posts on how to make one and watching Bobby_M's video decided to make my own, it turned out pretty good considering i haven't soldered in 5 years.
25 feet of 3/8--$30
4 feet of 1/2--$5
Is there something I need to do to prep this thing before i use it, or can i just wash with oxyclean and start using it?
