Here are five common household items that you should regularly replace to help prevent the spread of germs:
– Bath sponges: These have the great honor of potentially spreading mold and bacteria all over your body, so you should wring them out and dry them after each use. Loofahs should be replaced every month because the bacteria can grow in their nooks and crannies easily, but synthetic sponges are more resistant and can last up to eight weeks.
– Kitchen sponges: Cleaning, nuking, and drying out your kitchen sponges between washes will help keep them bacteria-free, but you should throw out heavily used sponges every two weeks, or up to eight weeks for those used less vigorously.
– Toothbrushes: It's always a good idea to toss your toothbrush after you get over a sickness, and in general, replace yours every three months.
– Mattresses: These should be replaced every seven years since any uneven sagging can cause you to have trouble sleeping, not to mention their permanent collection of dust, dirt, and allergens.
– Cutting boards: While there's no set time limit for when to replace your cutting boards, you should toss them if you notice discolored grooves, deep clean them regularly, and don't forget to use a separate one for raw meat!
