Dip a halved lemon in salt for a bit of gentle abrasive power, then scour brass, copper, or stainless-steel pots, pans, and sinks. Rub a cut lemon (sans salt) on aluminum to brighten it. Used lemons tossed in the disposal will deodorize it.
6. Get the most from every fruit.
Before juicing, roll a room-temperature lemon under your palm to break down the cells inside the fruit that hold liquid. If a fruit is especially hard (and sometimes it’s hard to find a good one in an entire supermarket bin), microwave the fruit for 20 seconds. You should get 2 to 3 tablespoons of juice per fruit.
