(AP) -- Phil DeVore pulls a folded piece of aluminum from a murky pond. The aluminum looks like a piece of siding that's blown off a building, but DeVore knows it's much more valuable than that.

Storing Used Oil. Used oil can be successfully stored in a cool, dark place for up to a month. Refrigeration or freezing increases the oilâs lifespan by several months. The oil may become cloudy during storage but this is not harmful and the oil will become clear upon reheating.

Grape seed oil can be stored without refrigeration for 3 months if the storage temperature does not climb above 70ÂºF, however since it contains a high level of polyunsaturated fat, it is best to store it in the refrigerator for up to 6 months. Storing the oil in an area of excessive heat will cause it to deteriorate rapidly. Hazelnut Oil
