You just brought home a brand-new set of sheets, and they feel crisp and perfect in the package. But should you wash new sheets before they touch your mattress? For most people, the answer is a clear yes — and it has nothing to do with getting out factory wrinkles.
Why New Sheets Need a First Wash
During manufacturing, fabric often receives a finish called sizing, a starchy substance that keeps the threads stable while the sheets are cut and sewn. Sizing rinses out in the wash, but until then it can leave new material feeling stiff or slightly coated. The packaged sheets also travel through warehouses, trucks, and stores, picking up dust and debris along the way.
The bigger reason to wash, though, is your skin. Some finishing chemicals and dyes can irritate people with eczema or sensitivities, so a quick wash removes those residues before they spend eight hours against your face. Many dermatologists and textile specialists advise washing new bedding for this reason, even if the sheets look perfectly clean.
How to Wash New Sheets
The routine is similar to your regular bedding wash, just with a little more attention to the settings.
- Check the care tag first. Most cotton or cotton-blend sheets wash beautifully in warm water, but if the tag says cold, use that instead.
- Use a mild, fragrance-free detergent. It’s less likely to irritate skin and won’t mask the clean smell of fresh cotton.
- Skip fabric softener on this first load. New sheets don’t need it, and the waxy coating can dull the crispness you bought them for.
- Wash the sheets alone or with similar soft items. A zipper or hook from another piece of laundry could easily snag the weave.
- Dry on low heat and remove while still slightly damp. Line drying works just as well and can help the weave stay true.
💡 Note: If your sheets are 100% cotton, a small amount of shrinkage after this first wash is normal. Line drying or low heat helps keep it to a minimum.
Are There Any Exceptions?
A few manufacturers stonewash or pre-wash their bedding before packaging, which removes much of the residue and softens the material in advance. If a brand explicitly says its sheets are pre-washed, you can likely skip the first wash. When in doubt, wash anyway — it’s still a simple way to remove travel dust from the package.
So next time you unbox a set, treat the first wash as part of the experience. Toss them in with a gentle detergent, go about your day, and make the bed with sheets that feel exactly how you hoped they would.
