How to Wash a 22 Momme Silk Pillowcase

A silk pillowcase does not need an elaborate cleaning ritual. It does, however, benefit from a gentler approach than cotton. The safest method is simple: use cool water, a small amount of silk-safe detergent, minimal friction, and no dryer heat.

This guide is written for the current Muse & Airy pillowcase: 100% mulberry silk, 22 momme, double-sided silk, with a hidden zipper. Its care label calls for hand washing in cool water at no more than 30°C (86°F). If the label on your own pillowcase says something different, follow that label first.

The short answer: Hand-wash separately in cool water (maximum 30°C / 86°F) with a mild, pH-neutral silk detergent. Do not soak, bleach, scrub, or wring. Press out water gently, reshape, and dry flat in the shade. Do not tumble dry.

What Does 22 Momme Change?

Momme is a measure of silk fabric weight. A 22 momme weave generally feels denser and more substantial than a lighter 19 momme fabric, but it is still silk. The higher weight does not make hot water, harsh detergent, or vigorous spinning safe.

In other words, momme can tell you something about the fabric’s weight and feel; it does not replace the care label. Dye, finishing, seams, and closures also affect how a finished pillowcase should be washed.

What You’ll Need

A clean basin or sink. Rinse it first so there is no residue from household cleaners.

A silk-safe detergent. Choose a mild, pH-neutral liquid formula. An enzyme-free product is a sensible choice for silk.

A clean, colorfast towel. Use it to absorb moisture without twisting the fabric.

A flat drying surface. A drying rack topped with a clean towel works well, provided it is away from direct sun and heat.

How to Hand-Wash a 22 Momme Silk Pillowcase

Step 1: Check the label and prepare the pillowcase

Remove the pillow insert. Close the hidden zipper gently so its teeth and pull do not catch on the silk. If practical, turn the pillowcase inside out. Wash it separately, especially during the first few washes or when cleaning a darker color.

Step 2: Fill a clean basin with cool water

Use cool water, no warmer than 30°C (86°F). You do not need ice-cold water; you simply want to avoid heat. Try to keep the wash and rinse water at a similar temperature rather than moving silk abruptly between hot and cold water.

Step 3: Add a small amount of pH-neutral detergent

Follow the detergent maker’s dosage for a small hand-wash load. More soap does not mean a cleaner pillowcase, and excess detergent is harder to rinse from a dense 22 momme weave. Dissolve or disperse the detergent in the water before adding the silk.

Step 4: Wash gently—and keep it brief

Lower the pillowcase into the water and move it gently with your hands. Lightly swish and press the water through the fabric for about one to two minutes. Do not scrub the surface, rub one section against another, or pull at the seams. Because the Muse & Airy label says “do not soak,” keep the wash brief and do not leave the pillowcase sitting in the basin.

Step 5: Rinse thoroughly

Drain the wash water and refill the basin with clean, cool water. Support the pillowcase as you lift and lower it; wet silk should not be pulled by one corner. Repeat with fresh water until the water is clear and the fabric no longer feels soapy.

Step 6: Remove water without wringing

Let excess water drain, then press the pillowcase gently between your hands or against the side of the basin. Lay it flat on a clean towel, roll the towel loosely, and press. Do not twist or wring the pillowcase—this can distort the fabric, seams, and hidden zipper area.

Step 7: Reshape and dry flat in the shade

Unroll the towel, smooth the pillowcase back into shape, and lay it flat to dry in a well-ventilated place. Keep it away from direct sunlight, radiators, hair dryers, and other concentrated heat. Do not tumble dry. Turn it over once during drying if the surface underneath remains damp.

Step 8: Use a cool iron only if needed

Many wrinkles relax once the pillowcase is placed on a pillow. If you want a smoother finish, iron on the lowest suitable setting while the fabric is slightly damp, preferably from the reverse side with a clean pressing cloth. Avoid heavy pressure and do not hold the iron in one place. Keep direct heat away from the zipper.

Can You Machine-Wash a 22 Momme Silk Pillowcase?

The honest answer is: check the care label. Some silk pillowcases are specifically tested and labeled for a delicate machine cycle. Others are labeled for hand washing only. Momme weight by itself does not decide this.

The current Muse & Airy care label specifies hand washing, so that is the method we recommend. A mesh bag and delicate cycle may reduce friction for a pillowcase whose own label permits machine washing, but they do not override a hand-wash instruction.

What Is the Best Detergent for a Silk Pillowcase?

Look for a liquid detergent labeled for silk or delicate fabrics, with a neutral or near-neutral pH. Preferably, it should be free from bleach, optical brighteners, and protease enzymes. Use only the recommended amount.

Avoid standard heavy-duty laundry detergent, chlorine or oxygen bleach, stain-removing powders, dish soap, and strongly scented formulas. Silk does not need fabric softener; softener can leave a coating rather than truly improving the fabric.

Baby shampoo is often suggested online, but it is formulated for hair and skin—not for rinsing cleanly from finished silk fabric. A purpose-made silk detergent is the more predictable option.

How to Treat Makeup, Skincare, or Oil Stains

Treat a mark as soon as practical, but do not attack it aggressively. Blot any fresh residue with a clean white cloth. Do not rub, because friction can spread the stain and change the sheen of the surrounding silk.

Test your diluted silk detergent on an inconspicuous area first. Then dab a small amount of the diluted solution onto the mark, working lightly from the outside toward the center. Rinse and wash the full pillowcase using the normal hand-wash method. Avoid household stain hacks involving baking soda, lemon juice, vinegar, alcohol, or peroxide; changes in pH or color can be more difficult to reverse than the original stain.

For a set-in or unknown stain, especially on a light color, a professional cleaner experienced with silk is the safer choice. Show them the care label before treatment.

How Often Should You Wash a Silk Pillowcase?

Once a week is a practical starting point for most people because a pillowcase regularly contacts hair, skin oils, skincare products, and perspiration. You may prefer every three to four days if you use rich overnight products, have oily hair, sweat heavily, or simply like a very fresh sleep surface.

Owning two pillowcases makes this easier: one can be in use while the other is being washed and air-dried. The right schedule is the one that keeps the pillowcase clean without subjecting it to unnecessary washing.

Why Does Silk Sometimes Feel Stiff or Look Dull After Washing?

A temporary stiff or dull feel is often caused by detergent residue, too much detergent, mineral-rich water, heat, or rough handling. Start by rinsing the pillowcase again in clean, cool water and letting it dry flat. Do not try to restore shine with fabric softener or high-heat ironing.

Silk may also look slightly different while wet. Judge the finished result only after it has dried completely and been gently smoothed by hand.

Common Silk-Washing Mistakes to Avoid

Using hot water. Heat can affect color, finish, and shape.

Soaking for too long. Follow the label; for this pillowcase, do not soak.

Scrubbing a stain. Friction can leave a visible change in sheen.

Wringing or twisting. Wet fabric and seams can stretch out of shape.

Using a tumble dryer. Mechanical action and concentrated heat are unnecessary risks.

Drying in direct sun. Strong sunlight can affect color over time.

Simple Care Between Washes

Let skincare products absorb before going to bed, and avoid spraying perfume or hair products directly onto the pillowcase. In the morning, pull back the bedding for a short time so moisture can dissipate. Store a fully clean and dry pillowcase in a cool, shaded place rather than sealing it away while damp.

Frequently Asked Questions

Should I wash a silk pillowcase before first use?

It is optional. If you prefer to wash new bedding before use, follow the same gentle hand-wash method and care label. There is no need for a stronger “first wash.”

Can I use Woolite or another delicates detergent?

Only if the exact formula is suitable for silk, pH-neutral, and free from ingredients the product label tells you to avoid. Brand names can have multiple formulas, so check the current bottle rather than relying on the name alone.

Can I wash silk with cotton towels or sheets?

Separate washing is safer. Cotton is heavier and creates more friction, and zippers, hooks, and rougher fabrics can catch silk.

Can I put silk in the dryer on an air-only setting?

Not for this pillowcase. Its label says not to tumble dry. Dry it flat in the shade instead.

Can I steam a silk pillowcase?

A cool iron is the method specified on the current label. If you use any steaming device on a different silk product, follow that product’s label and test carefully; excess heat or water spotting can affect some finishes.

Does 22 momme silk take longer to dry?

A denser fabric may retain more water than a lighter one, but drying time also depends on airflow, room temperature, and humidity. Give it enough time to dry completely before placing it back on the pillow.

Final Thoughts

Caring for a 22 momme silk pillowcase is less about doing more and more about avoiding the few things silk does not need: high heat, strong chemicals, and aggressive movement. A short cool hand wash, a careful towel press, and flat drying in the shade are usually all it takes.

With a simple routine, silk can remain a practical part of everyday sleep—not something reserved for special occasions.
