How to Wash Silk: The Ultimate Care & Maintenance Guide
This is your guide to washing silk pillowcases and bed linen, with seven practical steps for detergent, washing, drying, ironing, stains, bed making and storage. We also explain where other silk items might need different care.
How do you wash silk?
We recommend washing silk pillowcases and bed linen separately from other laundry, using a silk or delicate machine cycle with a mesh laundry bag, or a gentle hand wash. Use cool water below 30°C (86°F) and a pH-neutral, enzyme-free delicate detergent that is suitable for silk. Rinse thoroughly, press out excess water in a clean towel and air dry in the shade. Never wring, tumble dry, dry over a heater or in direct sunlight.
Both machine washing and hand washing work for Mayfairsilk pillowcases and bed linen. Choose the method that suits you in step 2. Sleep masks and other accessories have their own care instructions. The separate notes for other types of silk items cover unfamiliar brands, dry clean only garments and embellished clothes.
Your seven care steps: 1. Choose detergent. 2. Wash. 3. Dry. 4. Iron or steam. 5. Remove stains when needed. 6. Make the bed. 7. Store. If you have a stain, read step 5 before washing.
1. Choose a detergent made for silk
Use a pH-neutral liquid detergent made for delicate fabrics, without enzymes, bleach or optical brighteners. You do not need a product marketed exclusively as a silk detergent: many specialist wool and cashmere washes are also suitable for silk. Check the bottle or the manufacturer's directions to confirm silk suitability.
“Non-bio”, “eco”, “gentle” and “mild detergent” do not automatically mean silk-safe. Look for a specialist delicates formulation. For example, Woolite Delicates lists silk, wool and cashmere among its suitable fabrics and states that it contains no bleach or enzymes. Persil Silk & Wool is another example. Use the specific suitable product, rather than assuming every detergent in a brand’s range has the same formula.
Why silk, wool and cashmere need a delicate detergent
Silk, wool and cashmere are protein fibres: silk is mainly fibroin; wool and cashmere are mainly keratin. Cotton, linen and bamboo-derived viscose are cellulose-based. Surfactants lift oils and dirt, while protease enzymes break down protein stains and can also attack protein fibres. This is why a specialist delicates formulation matters. Many wool and cashmere washes suit silk too; check the specific product. For pH, enzymes, choosing a detergent and what to do after a washing mistake, read why silk needs a delicate detergent.
Measure the recommended dose for your load and water hardness. Extra detergent can leave residue, making the fabric feel stiff or streaky. Do not add fabric conditioner unless the silk manufacturer's instructions permit it.
2. Wash your Mayfairsilk: machine washing or hand washing
Give your Mayfairsilk its own wash, separate from towels, everyday clothes and other fabrics. Wash whites, lights and dark colours separately. You can wash matching pillowcases and a fitted sheet together if there is enough room for the silk to move freely; split a full bed set into smaller loads rather than packing the drum.
For Mayfairsilk pillowcases and bed linen, choose 2.1 Machine washing or 2.2 Hand washing. Both work. You do not need to carry out a dye-transfer test before the normal washing routine described here.
For silk from other brands: follow that item’s label. Before washing an unfamiliar silk item, press a clean white cloth dampened with cool water against a hidden area. If dye transfers, ask its manufacturer or a silk specialist before washing. This check does not override a dry clean only label.
2.1 How to machine-wash silk pillowcases and bedding
Machine washing is a straightforward way to care for Mayfairsilk pillowcases and bed linen. Use a delicate mesh laundry bag, leave room for movement and choose a cool, gentle programme.
-
Prepare the silk. Turn pillowcases and duvet covers inside out. Close fastenings as the product instructions direct and keep loose ties contained.
-
Protect it. Place the silk in a Mayfairsilk mesh laundry bag for delicates large enough for it to move freely. Wash separately from other laundry. Do not force a large sheet into a small bag or overload the machine.
-
Check the settings. Choose the silk setting or delicate cycle. For Mayfairsilk, select cold water or a setting below 30°C. Check the wash temperature and spin against the care instructions; the programme name alone is not enough. Avoid a high-speed spin.
-
Measure detergent. Use the silk-safe dose, with no bleach or routine laundry boosters.
-
Remove promptly. Support the wet fabric as you lift it from the drum, then follow step 3. Never leave it bundled in the machine.
2.2 How to hand-wash silk in cool water
Hand washing is equally suitable for Mayfairsilk pillowcases and bed linen, especially smaller loads. Keep the silk moving gently, without leaving it to soak. For other brands, a hand-wash-only label means you should use this method rather than a machine.
-
Prepare the water. Fill a clean sink or bowl with cool water below 30°C for Mayfairsilk. Dissolve the recommended small amount of silk detergent before adding the fabric.
-
Wash gently. Submerge the silk and lightly agitate the water with your hands. Move it gently through the water without scrubbing, stretching or twisting. For Mayfairsilk, keep it moving rather than leaving it to soak.
-
Rinse. Drain the bowl and refill with fresh cool water. Repeat until the detergent is gone. Keep the rinse water at a similar temperature to the wash.
-
Lift with support. Gather the item gently in both hands instead of lifting heavy wet silk by one corner. Move straight to towel drying.
2.3 When to dry clean silk
Use a professional cleaner for dry clean only silk, uncertain dyes, intricate construction or stains you cannot safely treat at home. Choose someone experienced with silk and show them the care label. Explain what caused any stain and what you have already applied.
Ask about siloxane-based solvents. Our preference is to discuss a gentle siloxane-based cleaning process, such as decamethylcyclopentasiloxane (D5), used by GreenEarth Cleaning. GreenEarth describes its silicone solvent and cleaning process here. The cleaner must confirm that the process suits your item's label, dyes, trims and construction. A solvent name alone is not a guarantee of suitability.
Do not use trichloroethylene or other dry-cleaning solvents for home stain removal. Professional cleaning is an option for suitable Mayfairsilk items, rather than the only option for all silk.
3. Dry silk without twisting or wringing
-
Press out excess moisture. Lay the silk flat on a clean, dry towel. Fold or loosely roll the towel around it and gently press. Do not twist the roll or wring the silk. Use a fresh towel if the first becomes saturated.
-
Reshape gently. Unroll, lift with support and ease the fabric back into shape. Smooth out folds without pulling on the seams.
-
Air dry in the shade. Lay the item on a suitable drying surface or drape bedding across several smooth rack bars so its weight is supported. Leave room for air to circulate.
Keep silk away from direct sunlight, radiators and other heat sources. Do not tumble dry. Avoid rough pegs, sharp door edges and unfinished or stained wooden rods, which can snag the fibres or transfer colour. If you line dry or hang a garment, follow its label and avoid stretching it under its own wet weight.
Silk often dries relatively quickly, but size, humidity and airflow matter. Check seams and folded edges before putting it away.
4. Iron silk or steam gently to remove wrinkles
Many creases relax with use. For a smoother finish, follow the care label:
-
Ironing: turn washable Mayfairsilk inside out and iron while slightly damp, using low heat or the iron's silk setting. Test a hidden area first and use a clean pressing cloth. Keep the iron moving.
-
Steaming: use a suitable handheld steamer with its silk attachment, following the appliance instructions. Test first and keep the head at the recommended distance. Stop if it spits water or marks the surface.
Never use a hot iron. Do not assume steam is harmless: excessive heat or water droplets can mark delicate silk. Some textured silk clothes require different treatment; their label controls. Silk supplier Pongees explains these fabric-specific ironing differences.
5. Remove stains from silk with the right treatment
Act promptly, but do not scrub. Lift away excess material and blot a fresh spill with a clean white cloth. For washable silk, use cool water and a silk-safe treatment only after checking both labels and testing a hidden area. Stop if colour transfers or the surface changes. Do not spot treat dry clean only silk at home.
Everyday marks: skincare, perspiration and light spills
If your silk detergent permits pre-treatment, use it exactly as directed, then rinse and wash the whole item according to its label. Do not leave concentrated detergent sitting on the cloth or let the treatment dry. Washing the item afterwards can help avoid a visible treatment ring.
Stubborn stains: the specific Vanish gels
Vanish's current UK guidance identifies Vanish Oxi Action Multi Power Gel as suitable for silk. Its product page also identifies Vanish Oxi Action Crystal White Gel for delicate whites. This is the only Vanish product that is suitable. Please check the exact product in your hand if unsure as they have a number of products that look quite similar.
For the Multi Power Gel, Vanish's silk-specific pre-treatment instructions give this method:
-
Test a hidden area for colourfastness first.
-
Apply 2 ml of the gel to the stain and work it in gently, without vigorous rubbing.
-
Leave it in contact for no longer than 10 minutes.
-
Wash according to the silk care instructions or rinse thoroughly, following the current packaging.
For Crystal White Gel, follow its own directions and use it only on suitable white items. Never substitute chlorine bleach, generic oxygen powders, enzyme stain removers or a product that does not explicitly allow silk. If the exact gel is unavailable in your country, choose a locally labelled silk-safe treatment or consult a professional. For oil, ink, old stains or a valuable garment, a silk specialist is the better next step than repeated experiments.
6. Make the bed without straining your silk
Good care continues after the wash. Pulling hard on a pillowcase opening or a duvet-cover seam puts unnecessary strain on the fabric.
Fit a silk pillowcase
-
Gather the pillowcase from its opening into a loose ring, like a doughnut, without stretching it.
-
Gently compress the pillow lengthways so it passes through the opening. Push the pillow in rather than pulling hard on the silk.
-
Match the far corners, then unroll the pillowcase over the filling with your free hand.
-
Align the remaining corners, tuck the pillow into the envelope pocket and give it a gentle fluff.
Fit a duvet cover and fitted sheet
Use your Mayfairsilk duvet cover's corner ties with the duvet's corresponding loops, securing them before turning the cover right side out. Support the duvet while distributing it; do not shake its full weight from the silk corners.
Check the mattress and topper together against your fitted sheet's stated dimensions. Ease the elastic over each corner in turn rather than hauling the last corner into place. A deeper mattress needs the right sheet depth. If the fabric is under tension, check the fit before pulling harder.
7. Store clean silk in a breathable cotton bag
Store silk only when it is clean and completely dry. Fold bedding loosely into a breathable cotton bag and keep it in a cool, dry wardrobe away from direct sunlight. Avoid airtight plastic bags or boxes that can trap moisture.
For suitable silk garments, use padded hangers to support the shoulders. Leave space around them, check stored silk periodically for damp or moth activity, and keep any moth-control product away from direct contact with the cloth.
Silk care questions, answered
Can you wash 100% Mulberry silk?
Yes, when its care label permits washing. Fibre content alone does not determine the method: dyes, finishes, linings and trims matter too. Follow the washing instructions for the finished item, including silk sleep masks with padding or adjustable fastenings.
Can I wash silk in cold water or at 30°C?
Cold water is suitable for washable Mayfairsilk with the right detergent. Our guidance is below 30°C (86°F), rather than assuming a 30°C programme runs cooler. “Lukewarm water” is imprecise, so check the actual temperature. Hot water can cause shrinkage, colour loss or changes in texture.
Why does my silk pillowcase feel rough after washing?
Detergent residue, hard-water deposits or heat damage are possible explanations. Check your detergent, dose and programme. If residue seems likely, rinse washable silk gently in cool water and air dry. Do not try to soften it with more detergent or a hotter wash; contact the maker if the change persists.
Should I use distilled white vinegar on silk?
Fresh-water rinses are normally all your Mayfairsilk needs. If it feels stiff or dull after a detergent mistake, first rinse gently to remove residue. Our detergent recovery guide explains when a carefully diluted white vinegar rinse may help, when to avoid it and why it cannot repair damaged fibres.
How often should I wash a silk pillowcase and sheets?
As a practical starting point, wash pillowcases weekly and sheets every one to two weeks, adjusting for use. Wash sooner after heavy perspiration, illness, spills or a build-up of skincare and hair products. Silk still needs regular cleaning; its smooth surface does not make it self-cleaning.
Can I wash a silk-filled duvet using these steps?
Do not confuse a washable silk duvet cover with a silk-filled duvet. Filling and construction need their own instructions. Follow the duvet manufacturer's label instead of applying this bed-linen routine.
These simple steps keep silk care manageable: the right detergent, cool water, gentle handling and no unnecessary heat. Explore Mayfairsilk silk pillowcases and keep this guide to hand for the next wash.
