How to wash a silk pillowcase

If the care label permits washing, wash a silk pillowcase by hand in cool water with a pH‑neutral, enzyme‑free detergent, rinse well, press in a clean towel and air‑dry out of direct sunlight. If and only if the care label allows, you can machine‑wash cold on a delicate cycle inside a mesh bag, then air‑dry. A silk sleep mask can have different fillings, adhesives or trims, so do not assume it can be cleaned in the same way Good Housekeeping washing guide Mulberry Park Silks care guide.

Label first: choose hand or machine

Always follow the sewn care label; specific weaves, dyes, linings or trims can change what is safe. If the label says dry clean only or warns against machine washing, defer to that. For items without strict limits, hand‑washing is the safest default; machine washing is acceptable when protected in a fine mesh bag on a cold delicate cycle and removed promptly Mulberry Park Silks care guide Good Housekeeping washing guide.

Get these together before you wash silk

• pH‑neutral, enzyme‑free detergent for silk/delicates
• Fine mesh laundry bag (for machine washing)
• Clean basin and a white cotton towel for blotting
• Flat drying rack or a shaded hanging spot

Hand‑washing a silk pillowcase

1) Mix and submerge

Fill a clean basin with cool water and dissolve a small amount of pH‑neutral, enzyme‑free detergent. Turn the pillowcase inside out and submerge; gently agitate with your hands. Do not scrub, twist or wring the fabric Good Housekeeping washing guide Mulberry Park Silks care guide.

2) Rinse and blot

Rinse in cool water until suds are gone. Press water out gently. Lay the item flat on a clean, white towel, roll it up and press to absorb excess moisture. Avoid wringing or twisting to protect the fibers Good Housekeeping washing guide.

3) Dry out of sunlight

Reshape and air‑dry flat or on a rack in the shade. Keep silk away from direct sun and high heat, which can fade color and weaken fibers Mulberry Park Silks care guide.

Machine‑washing safely (only if the label permits)

Prepare the pillowcase by turning it inside out; if it has a zipper, close it. Place it in a fine mesh laundry bag. Wash on a cold delicate cycle with a pH‑neutral, enzyme‑free detergent; select a low spin and avoid washing with heavy or abrasive items. Remove immediately after the cycle, reshape and air‑dry out of sunlight Good Housekeeping washing guide George Street Linen expert guide Mulberry Park Silks care guide.

An illustrative care-label decision

Suppose a pillowcase’s label permits a cold delicate machine cycle but forbids tumble drying. Use that permitted cycle, the detergent’s stated dose and a protective mesh bag, then remove and air-dry the pillowcase as directed. This example does not override another product’s hand-wash-only or dry-clean-only label.

For a different item such as a sleep mask, check its own construction and instructions. See the separate sleep-mask washing guide rather than applying a pillowcase procedure to padded or bonded components.

Stains, frequency and when to stop

Spot‑treat gently

Treat stains promptly. Work a small amount of diluted silk‑safe detergent into the spot with your fingertips, then launder using the chosen method. Avoid bleach and harsh stain removers on silk to prevent fiber damage or discoloration Good Housekeeping washing guide Mulberry Park Silks care guide.

How often to wash

Wash a silk pillowcase about once a week in regular use. Adjust the interval for use, visible soiling and the product instructions Good Housekeeping washing guide. For more on cadence, read How often should you wash your pillowcase?

Test color and know when to seek help

Before first washing, spot‑test for colorfastness on a hidden area; if dye transfers, do not wash at home. If you notice color bleeding, shrinkage or persistent stains, stop and consult a professional cleaner who handles silk Mulberry Park Silks care guide.

Finishing and storage

If the label permits ironing, use its recommended silk setting and a suitable pressing cloth. Do not assume steaming is allowed; finishes and dyes can react differently. Store silk clean and dry in a cool, dark place; avoid sealed plastic that can trap moisture Good Housekeeping washing guide Mulberry Park Silks care guide.
