We all know we’re supposed to wash our sheets frequently (maybe more frequently than we do!). But what about the other parts of your bed: comforters, duvet covers, pillows, decorative pillows, mattresses and all those extra blankets? Well, it turns out you need to wash all those too, and maybe on different timelines than you’d expect. If you wash too frequently, your precious bedding can deteriorate more quickly. Too infrequent, and your bedding will “accumulate significant amounts [of] dirt, dead skin cells, body oils, sweat, [and] dust mites,” according to the Sleep Foundation.

So, what’s the perfect balance of washing for each part of your bedding? We’re glad you asked.

Sheets and Pillowcases

Let’s start with the basics. You need to wash your sheets and pillowcases at least once a week, according to the Sleep Foundation. However, if you have pets—and especially if they sleep with you—you should wash your sheets every few days. This will help minimize allergens, which could cause sneezing or skin irritation. We also love performing a full disinfection of our sheets.

Duvet Covers

First off, if you don’t use a top sheet, you should wash your duvet cover as frequently as you would wash a top sheet (at least once a week). If you do have a top sheet acting as a barrier between your body and the duvet, wash your duvet cover about once a month. Learn how to store your bedding.

If you use a duvet cover on your comforter, Mulberry’s Garment Care suggests washing it a few times per year, as with the change of seasons. However, if you don’t use a duvet cover, wash it once a month, and if you have neither a duvet cover nor top sheet, wash it once a week like a sheet. This will, however, potentially speed up the wear of your pricy down comforter, so using at least a top sheet is ideal (although, you can also try the Sunday Citizen comforter, as it replaces your duvet, duvet cover, and top sheet all in one go). Oh, and if you’re a hot sleeper, the Evercool cooling comforter is the perfect pick for you.

Aim to wash your pillows twice a year. To be safe, always check the pillow’s tags before washing, though most are safe to either machine- or hand-wash. Additionally, if you are a heavy nighttime sweater, consider washing pillows more frequently, such as with the seasons. If your pillows have any yellow stains, here’s how to whiten them.

If you use throw pillows on your bed and rest on those throw pillows as you would those on a couch, you need to wash them every other month. You can typically toss the whole pillows into a washing machine, but if they have delicate embroidery or heavy texture, try to wash only the pillow covers.

Extra Blankets

How often you wash extra blankets will depend on how often you use them. If the blankets are strictly decorative, aim for once a month. If you curl up under those cozy blankets nightly, wash them once a week. Here is how to wash a weighted blanket.

Lastly, you do, in fact, need to wash your mattress. According to mattress manufacturer Serta, you should deep-clean your mattress every few months. Use the handheld attachment on your vacuum cleaner to suck up any dirt and dust. For stains, you’ll need to scrub them with baking soda and hydrogen peroxide, being careful not to oversaturate the mattress with water, which can mildew.
