Well, if you buy but never use them they'll last a lifetime. For most people, however, home care products generally have a shelf life of one year if opened and two years unopened. Even then it's still best to store your products in a cool place with no exposure to direct sunlight. Also, be sure to only allow a bottle or jar to remain exposed the air for the shortest time possible. Keep husbands, kids and housemates away from your products as they'll likely be used up well bef
