Red Pontiac potatoes are thin-skinned and won't require peeling when used in potato salad. Don't wash your Pontiac potatoes prior to storing; wait and wash the potatoes when you are ready to use them. If the potatoes are stacked together during storage, one spoiling potato can instigate spoilage in its neighbor. To avoid rotting, don't allow the potatoes to touch each other during storage.
Arrange the potatoes in a single layer on a pallet covered with several sheets of newspaper, or a box with a screened bottom, or open-weaved-bottom vegetable bin, for proper ventilation. Ideally, the potatoes should not be touching.
Store the Red Pontiac potatoes in a cool, dry, dark location at temperatures between 45 and 50 degrees F.
Check the potatoes several times a month and discard any potato that shows signs of spoilage or sprouting. Store the Red Pontiac potatoes for up to five months.
