Was wondering if the cleaner will take it off?
PBW will definitely take care of this. But help me understand where the mold is exactly. Is this an Immersion Chiller or a Counterflow?
If the chiller is copper are you sure it’s mold and not verdigris? If you could post a photo it would help a lot.
I think he is talking about the clear vinyl lines typical of an immersion chiller.
Greg that was my assumption as well but thought I would ask for clarification.
