Hi, I have a chill wizard with a brazed plate hx. Don't feel like I can really clean it that well since the plates are fused together. Tons of people recommend circulating the boiling wort through it for 5-10 minutes to kill bacteria, which I did the last few times, but I'm still getting infected. Are there any small plate chillers that can be disassembled? A bit mystified about what's happening.
