Why are holes forming in the aluminum pans?
So I do salads and I put a number of my toppings in the small square aluminum pans. Items like cucumbers tomatoes chesee feta mozzarella and so on on the cold storage side. Recently I have been coming back the next day after wrapping the containers with foil an leaving in chiller for next day I see water underneath on close inspection I see little holes in a few pans. Looking like something ate a hole?
