A handy, who-knew guide to 77 foods, beauty products, and household goods 
Keate
Certain items in your house practically scream "toss me" when their prime has passed. That mysterious extra white layer on the Cheddar? A sure sign it needs to be put out of its misery. Chunky milk? Down the drain it goes.
But what about that jar of olives or Maraschino cherries that has resided in your refrigerator since before the birth of your kindergartner? Or the innumerable nonedibles lurking deep within your cabinets and closets: stockpiled shampoo and toothpaste, seldom-used silver polish? How do you know when their primes have passed?
With help from experts and product manufacturers, Real Simple has compiled a guide to expiration dates. These dates are offered as a rough guideline. The shelf lives of most products depend upon how you treat them. Edibles, unless otherwise indicated, should be stored in a cool, dry place. (With any food, of course, use common sense.) Household cleaners also do best in a dry place with a stable temperature. After the dates shown, beauty and cleaning products are probably still safe but may be less effective.
