We are in the process of installing optical sorters (which the FDA sees as a Food Contact Surface) into our process (nuts). We sell it as a raw (non kill step, aW below .6) product. I was wondering what glass/cleaner anyone recommends that the FDA wont have a fit about. Plant Manager says WIndex, I said not in Production areas (only in office and break room). I know I'm correct, but trying to find solutions so we can keep our new sorters clean.
