I just got a brand new 50' stainless steel immersion chiller from NY Brew yesterday. What a great deal and the quality is top notch. My question is: The directions say to clean the coils of any machining oil prior to first use. Says to use TSP or equivilent. Looked locally and cannot find any. Can someone who also has this rig clue me in on what you did or what was used to clean the oils off?
