Hi, I've made myself a 10mm copper cooling coil today . I presume I should clean this before first use, and just wondering what others have done. I'm tempted to boil up some water in the boiler and pop it in for 10 mins? Just concerned about anything on the copper I need to remove before first use, thus not ruining a brew. I'm also thinking about making a VWP solution and wiping the coil and rinsing?? Cheers.
