I was retrieving items from a storage unit. The person requested I pull boxes with kitchen items. Image my surprise while transporting the boxes I could smell balsamic vinegar. I stopped and discovered a box was soaked with various oils and vinegars that were out of date.
Most people think the items they will place in a storage unit will be there a month or so. This is not the case. It is best not to place food items in a storage unit.
These partially used food items can be donated to various food programs or given away to friends. It is best not to have food products which invite critters and mold into your storage unit!
