The word is out about hand washing. If you do it right and often, you can get rid of bacteria that could make you sick. But attacking germs where you pick them up makes it less likely you’ll get them on your hands in the first place.

In the kitchen: Sink handles, sinks, and counters are the biggest offenders. Clean sinks, sink drains, and counters with antibacterial soap at least once a day. Wash your sponge in the dishwasher to kill germs.

Fresh vegetables and fruits: They may carry salmonella, campylobacter, or E. coli, say microbiologists at New York University. Rinse them thoroughly.

In the laundry: Add bleach to a load of white clothes that includes underwear. It kills virtually all of the germs on underwear so they don’t spread. Move the load immediately to the dryer and dry at a high temperature.

In the bathroom: Use a disinfecting cleaner on the bathtub weekly. If someone with a skin infection uses the tub, wash it with bleach right away so you don’t pick up the germs.

Shared devices: Use antibacterial cleaner frequently on telephones, TV remotes, door handles, and shared keyboards, especially if someone in the household has an illness.
