How often do you wash your bed sheets?

=== once a week is the rule in my house --- has been for 70 years ............

Once a week. I use whatever laundry detergent is cheapest and add 1/3 cup bicarb soda to boast the cleaning power and absorb odours of any kind, including the laundry powder perfume. I have white sheets and they are snowy white and "fresh" when dry.

every other day for the last 50 years...do you know what is on your body that transmitts to your sheets? if you did you wouldn't wash them only once a week or longer...and I use hot water , not cold or warm, and good old lye soap it's the best and you don't need fabric softner,bleach or dryer sheets! Saves lots of money!

seriously people sheets need to be washed more than once a week !

Every 2 weeks. I use Tide Clear HE.

I wash mine probably every week and a half or every 2 weeks.

Once a week in this sweltering heat here. I use Gain original.

every 3 weeks

Once a week. If I get sick then it would be more often. I use Arm & Hammer liquid

i wash my sheets like once a month or longer
