Cook Chill Kettle-Black Film?
Started by therecipe, May 27 2015 07:59 PM
We are coming up with a black film on out cook chill kettles. By appearance they look clean but when wiped down a black film show on the cloth. No sanitation process have changed and no new products have been introduced. We are speculating oxidation of the stainless steel kettle? Has anyone had experience with this issue and have suggestions on how to resolve it?
