A while back, asked readers how often you wash your sheets. Turns out, the majority of you strip the bed every 10 to 14 days, while a good many of you go three and even four weeks in between washings! Eek! That got us thinking that perhaps some guidelines about when to wash what might be useful.

Household Items You Don’t Clean (But Should)

Sheets: Once a week

Sheets should be washed often to remove a buildup of debris, dust, sweat and other icky things. Use hot water (130 to 150 degrees Fahrenheit) and a hot dryer cycle to kill all germs.

Cars: Every one to three weeks

If you live near a large body of water, live somewhere with extreme weather conditions, drive a lot or park outside, a once a week washing is a good idea in order to protect the finish. Otherwise, every two to three weeks is sufficient

Dogs: As needed

Let your nose be your guide! If your pooch is getting smelly, or if he feels oily to the touch, then it’s time to wash. Certain breeds, like cocker spaniels, are prone to oily skin, so definitely suds them up once a month. Dogs with thick hair like chows only need to be bathed three to four times a year.

When to Replace Household Items

Jeans: Every four to five wears

It’s ok to wear your heavy denim jeans several times before washing, as long as they’re not stained. Over-washing can cause them to wear out prematurely.

How to:

1. Turn jeans inside out and wash in cold water.

2. Drip dry.

Bras: Every 3 to 4 wears

A general rule is that you should never wear the same bra two days in a row, because elastic needs time to reshape. Have a rotation of a few bras, and give each one at least 24 hours to recover before wearing it again. With proper rotation, bras can last several wears between washes.
