The natural protein that gives silk its smoothness, called fibroin, is indeed fragile and is not tolerant of harsh chemicals, heat damage, or rough handling like cotton or polyester.
Therefore, check the care label first. Even 22 Momme Grade 6A mulberry silk can vary in care requirements based on construction details. Some pillowcases may be washed in the washing machine, while others are hand-wash only.

So, a quick check saves you from an irreversible mistake, because silk loses up to 20% of its strength when wet, and wrong handling at that stage causes permanent damage.
Cleaning A Silk Pillowcase- Different Washing Methods
Hand Washing
Handwashing the silk pillowcase can be the easiest method as it gives you full control over the pressure, temperature, and how long it is rinsed. Perhaps this is the reason most experts prefer this method. All you have to do is fill a clean sink or basin with cool water. Then, add about 1 teaspoon of the pH-neutral, enzyme-free detergent.
Turn the pillow cover inside out and drop it in and gently swirl for 3-5 minutes. You do not have to scrub, clump, or twist it, as wet silk tears much more easily than dry silk. Once cleaned, rinse thoroughly with new, cold water until the water is clear.

Machine Washing
If your silk pillowcase is machine washable, place it in a mesh laundry bag before putting it in the washer. This extra layer of protection helps prevent the delicate fabric from snagging on zippers, buttons, or the agitator found in some top-loading washing machines. This leads to small tears that increase gradually. Use cold water (max 30°C / 85°F) to adjust the machine to a gentle or delicate setting. Use a detergent that is safe for silk and has a neutral pH formula.
Do not use a softener as it coats silk fibres and will cause the texture to fade with time. Take off the pillowcase right after the cycle finishes. However, keeping it in the machine causes wrinkles to form in the fabric, which are more difficult to eliminate from silk than from cotton.

How Often To Wash And How To Store
Wash silk pillowcase at least once a week. Even less absorbent than cotton, it absorbs skin oils, dust, and residues from hair and skincare products over time, which can impact fabric condition and skin health.
Wash more often if you are prone to acne, sweat a lot or have a bad day. It is a good idea to have an extra silk pillowcase on hand so you can switch them when needed. Since washing and drying silk usually takes around 45 a little time, having a spare helps you avoid any interruptions to your daily routine.
Store in a cool, dry place out of the sunlight. Don't fold silk tightly, as it creates sharp folds. Gently roll the pillowcase before putting it in an airy bag.

Putting A Silk Pillowcase in the Dryer?
It is generally not recommended to put a silk pillowcase in the dryer because heat can easily damage this delicate fabric. High temperatures may cause silk to shrink, lose its smooth texture, or even develop a yellowish appearance over time.
The safest option is to let the pillowcase air dry by laying it flat on a clean towel or hanging it on a padded hanger away from direct sunlight. Since silk dries fairly quickly, these methods help preserve its softness and shine.
If using a dryer is unavoidable, choose the no-heat or air-fluff setting, place the pillowcase inside a mesh laundry bag, and limit the drying time to no more than 5 to 10 minutes.
