There’s something comforting about climbing into a bed with brand-new sheets, but experts recommend washing them before your first night’s sleep. Even though they look spotless, new sheets have traveled through factories, warehouses, and store shelves, collecting dust, residue, and handling along the way. That crisp feel and “new sheet smell” often come from a chemical coating called sizing, which helps fabrics stay smooth and wrinkle-free during packaging.

A quick wash removes leftover sizing, excess dyes, and small amounts of finishing chemicals that may irritate sensitive skin. It also helps eliminate dust, lint, and other particles picked up during manufacturing and shipping. While these substances are generally considered safe, washing your sheets first creates a cleaner, more comfortable surface for sleeping.

Another benefit is softness. The first wash breaks down the stiff coating, allowing the fibers to relax and become noticeably softer. It also helps smooth out deep packaging creases, leaving your bed looking and feeling fresher. For the best results, wash new sheets in cool or warm water with a gentle detergent, separate dark and light colors, and dry them on low or medium heat.

If you’re buying cotton sheets, adding a little baking soda during the wash and white vinegar to the rinse can help remove odors and naturally soften the fabric. Taking a few extra minutes to wash new sheets before using them ensures your first night is cleaner, softer, and far more comfortable.
