Scour a barbecue grill or remove stuck-on food from pots, pans and oven racks. Scrub rust off chrome and steel. To sharpen dull garden shears and scissors, cut through folded layers of foil a few times. For heavy-duty garden shears, fold the foil even thicker.

To keep birds and deer away, hang strips of foil on strings in the garden. What else to do with used foil: Wrap leftovers in used foil, but if the foil has come in contact with raw meat, do not reuse it for other food purposes.
