We have our first audit coming up next month, and I'm going line by line on things that I think need a little more detail to them. One issue I keep coming up with, and cannot seem to figure out a solution, is labeling oil bottles. We use the bottles to spray our hoppers to transfer dough (I own a bakery) from mixer to production lines. While I can just write on the bottles with a marker, this does not seem to last more than about a week before the marker just wipes off due to the oil.
Anyone have a solution for this? Or should I just keep with the marker?
