Few fabrics feel as indulgent as silk and cashmere. A silk blouse that drapes beautifully for a Mayfair dinner, a cashmere jumper that gets you through a cold commute on the Northern line, a silk tie that finishes a sharp City suit: these are the pieces people treasure, and they are also among the easiest to ruin with one careless wash.
If you have ever wondered how to clean silk clothing without leaving water marks, or worried that your favourite cashmere will shrink to doll-size, you are in good company. Both fabrics are natural protein fibres, which makes them wonderfully soft but also sensitive to heat, friction, harsh detergents and, in London, our famously hard tap water.
This guide covers everything: what makes these fibres so delicate, how to clean silk clothing safely at home, when professional care is the smarter option, and a practical cashmere care guide to keep knitwear soft for years. We also cover specific items like ties and scarves, because they need different treatment from a blouse or a dress.
Why Silk and Cashmere Need Special Care
Silk is produced by silkworms and is made of protein, much like human hair. Cashmere comes from the fine undercoat of cashmere goats and is also a protein fibre. This shared chemistry explains why both fabrics react badly to the same things:
- High heat: hot water, hot dryers and hot irons can shrink, stiffen or scorch the fibres.
- Harsh chemicals: biological detergents contain enzymes that digest protein, and chlorine bleach can dissolve silk completely.
- Friction and wringing: twisting wet fibres distorts the weave of silk and causes cashmere to felt and pill.
- Perfume, deodorant and perspiration: these leave stains that often set permanently if they are left untreated.
Understanding this is the foundation of every piece of advice below. Treat both fabrics gently, keep temperatures low and avoid anything aggressive, and you will already be avoiding most of the common mistakes.

How to Clean Silk Clothing: Start With the Care Label
Before you do anything, read the care label. In the UK, garments carry standard symbols: a wash tub for washing, a triangle for bleaching, a square with a circle for tumble drying or dry cleaning, and an iron symbol. A tub with a hand means hand wash only. A tub with a cross means do not wash. A circle containing the letter “P” or “F” tells your cleaner which solvent type is suitable.
The first step in learning how to clean silk clothing is accepting that not all silk is the same:
- Washable silks such as habotai, charmeuse and many crepe de chine pieces can usually be hand washed.
- Structured or lined silks such as tailored jackets, silk dresses with internal boning, beaded or sequinned pieces and heavily printed fabrics generally need professional care.
- Raw silk, dupioni and taffeta water-spot very easily and are best entrusted to a specialist.
- Silk blends (silk with wool, viscose or elastane) follow the most delicate fibre in the mix.
If the label says “dry clean only”, believe it. Manufacturers use that wording because dyes, linings and construction may not survive water. If there is no label at all, a cautious approach is to take the item to a professional cleaner.
Can You Dry Clean Silk? The Honest Answer
This is one of the most common questions we hear from customers across London, and the short answer is yes. In fact, can you dry clean silk is almost a trick question, because dry cleaning is often the safest method for the fabric.
Dry cleaning uses specialist solvents rather than water, so there is no risk of water marking, colour bleed or shrinkage. A skilled cleaner will also choose a gentle solvent system, spot-treat stains by type and finish the garment by hand-pressing at the right temperature.
So when is dry cleaning the right call?
- The label says dry clean only. Always follow it.
- The garment is tailored or lined. Different fabrics inside one garment can shrink at different rates in water.
- The silk is heavily dyed or printed. Deep reds, navy blues and vivid prints are prone to bleeding.
- The item is embellished. Beads, sequins and embroidery are better handled professionally.
- There are stubborn stains. Oil, makeup, wine and perfume can be made worse by home treatment.
- It is a special occasion piece. A wedding guest dress or evening gown deserves a specialist.
If you would like expert hands on your wardrobe, our dry cleaning service in Clapham is designed for exactly this kind of delicate fabric.
One practical tip: do not dry clean silk too often. Constant exposure to solvents can dull some fabrics over time. Unless a piece is visibly stained or has been worn several times, airing it out between wears is usually enough.
Washing Silk at Home: A Step-by-Step Guide
If the label permits, washing silk at home is perfectly achievable and can save money on everyday pieces. This is the method we recommend for washable silks.
How to Clean Silk Clothing by Hand
This is the safest home method, and the one to use when you are unsure.
What you need: a clean basin, lukewarm water (no warmer than 30°C), a pH-neutral or silk-specific detergent, and a clean white towel.
Steps:
- Test for colourfast dye. Dab a hidden seam with a damp white cloth and a little detergent. If any colour transfers, stop and choose dry cleaning.
- Fill the basin with lukewarm water and add a small amount of detergent. Swirl to dissolve completely before adding the garment.
- Soak for no more than five minutes. Silk should not sit in water for long periods.
- Gently move the garment through the water with your hands. Do not scrub, twist or wring.
- Rinse in cool, clean water until the suds disappear. Because London water is hard and rich in minerals, a final rinse can help prevent a stiff, dull finish. A small splash of white vinegar in the last rinse is often recommended to cut through limescale, but test on a hidden area first.
- Remove the water without wringing. Lay the item flat on a clean towel, roll it up and press gently.
- Dry flat or on a padded hanger, away from direct sunlight and radiators. Sunlight fades silk and heat makes it brittle.
Can You Use a Washing Machine?
Some silk items allow it, but only if you use the delicate or hand-wash cycle at 30°C or below, a low spin speed, a mesh laundry bag and a silk-safe detergent. Never use fabric softener, which can leave residue, or biological powders, which attack the protein fibre. For anything valuable or sentimental, hand washing is the better choice.
Common Mistakes to Avoid
- Using hot water, which causes shrinkage and dulls the sheen.
- Using bleach, even in tiny amounts, which can eat holes in silk.
- Hanging wet silk in direct sun or on a radiator.
- Rubbing a stain, which spreads it and roughens the fibre.
- Leaving damp silk in a laundry basket, where it can develop mildew and marks.
How to Clean Silk Clothing Stains Without Damaging the Fabric
Stains are where most people go wrong. Whether you are dealing with a coffee splash on the way to Liverpool Street or a drop of red wine at a Soho bar, the golden rule is to blot, never rub.
- Water-based stains (tea, juice, wine): blot immediately with a clean white cloth. Dabbing with cool water from the outside inward helps stop the stain spreading.
- Oil or grease: sprinkle a little talcum powder or cornflour to absorb the oil, leave for a few hours, then brush away gently. Do not add water.
- Deodorant and perspiration: these cause yellowing and weaken the fibres over time. Wash silk after being worn close to the underarm, and avoid applying deodorant just before dressing.
- Makeup and perfume: these often contain dyes and alcohol that can mark silk permanently. Take the garment to a professional as soon as possible.
If a stain does not lift after one gentle attempt, stop. Further treatment at home can set the mark permanently. Tell your cleaner what caused the stain and when it happened, as this helps them choose the right treatment.
Silk Tie Cleaning: Why Ties Need Extra Care
Ties are among the most difficult accessories to clean. Unlike a flat piece of fabric, a tie has an inner lining, a hand-sewn construction and a shape that needs to be retained. Water and rubbing can leave it twisted, puckered or permanently marked, which is why silk tie cleaning is best left to a professional in most cases.
If you spill something on your tie:
- Blot gently with a clean, dry cloth. Do not rub.
- Do not use water, which can leave a ring mark that is harder to remove than the original stain.
- Leave it to dry naturally and take it to your cleaner as soon as you can.
Between wears, untie it fully rather than pulling the knot loose, as this prevents creasing and strain on the fibres. Hang it up overnight to let the fabric relax, and store it rolled or hanging, never crumpled in a drawer.
A professional silk tie cleaning service uses careful spot treatment and hand finishing to keep the shape, colour and sheen intact. It is a small investment, especially for designer ties from Jermyn Street or Savile Row. Add ties to your next suit and shirt order using our shirt and suit laundry service so everything comes back ready to wear together.
Silk Scarf Cleaning: Keeping Prints Bright and Edges Perfect
Silk scarves often combine delicate fabric with rich, saturated prints and hand-rolled hems, which makes them particularly vulnerable. Done well, silk scarf cleaning will preserve the colour and the soft drape. Done badly, it can leave you with bleeding dyes or a puckered edge.
For washable scarves:
- Always test colourfastness first.
- Wash separately from other items in cool water with silk-safe detergent.
- Never wring or twist. Press the water out in a towel.
- Dry flat, then iron on the lowest heat setting while still slightly damp, with a pressing cloth between the iron and the silk.
For luxury or vintage scarves:
Designer scarves, especially those with intricate prints or hand-rolled edges, should be professionally cleaned. Vintage pieces may have dyes that are no longer stable, so water can be risky.
Storage matters too. Fold scarves loosely or roll them rather than hanging them on narrow hooks, which can create marks. Keep them away from direct sunlight and store them in breathable cotton bags.
For anything you would hate to lose, our team offers specialist silk scarf cleaning within our delicate garment cleaning service.
Cashmere Care Guide: How to Keep Knitwear Soft for Years
Cashmere is luxurious, but it is also fragile. With the right approach, a good cashmere jumper can last decades. Use this cashmere care guide as your reference.
How Often Should You Wash Cashmere?
Less often than you think. Cashmere is naturally breathable and resists odours, so it rarely needs washing after a single wear. Air it out for a day between wears and wash only after four to six wears, or sooner if it is stained or smells of smoke. Over-washing is a major cause of pilling and fibre damage.
Hand Washing Cashmere
- Fill a basin with cool to lukewarm water (maximum 30°C).
- Add a small amount of wool or cashmere shampoo. Baby shampoo is a popular alternative, but a dedicated product is better.
- Submerge the garment and press it gently. Avoid agitation.
- Soak for 10 to 15 minutes.
- Rinse in cool water until it runs clear.
- Press out excess water with a towel. Never wring.
- Reshape and dry flat on a fresh dry towel, away from heat and sunlight. Never hang a wet knit, as the weight will stretch it out.
Dealing With Pilling
Pilling, those small balls of fibre, is normal for cashmere, especially under the arms and where a bag strap rubs. It does not mean the garment is poor quality. Remove pills with a cashmere comb or a fabric shaver, working in light, careful strokes. Avoid pulling them off by hand, which can damage the surrounding fibres.
Storing Cashmere and Protecting It From Moths
Moths are a genuine problem in London homes, particularly in older flats and period properties. Moth larvae feed on natural fibres like cashmere and can ruin a jumper before you notice.
- Wash or clean knitwear before storing it for the season. Moths are attracted to body oils and food residue.
- Fold rather than hang to prevent stretching.
- Use breathable cotton garment bags rather than plastic, which traps moisture.
- Add cedar blocks or lavender sachets. These help deter moths but do not kill them, so replace them regularly.
The most thorough end-of-season option is a professional clean before storage. Our dry cleaning and knitwear cleaning service removes the invisible residues that attract moths and returns your cashmere fresh, folded and protected.
Ironing and Steaming Silk and Cashmere
Heat is the enemy of both fabrics, so use it carefully.
- Silk: iron on the lowest setting (typically around 110°C, or the “silk” setting), on the reverse side, with a clean cotton pressing cloth. Never use steam directly on delicate silk, as it can leave water spots. A handheld steamer held a few centimetres away is a gentler option for removing creases.
- Cashmere: rarely needs ironing. If it does, use a cool iron with a damp cloth in between, and do not press the iron down firmly. A light steaming usually restores the surface.
If you are short on time, we can take care of the pressing for you. See our ironing and pressing service for details.
Choosing a Professional Cleaner in London
Not every cleaner treats delicate fabrics equally. When choosing where to take your silk and cashmere, look for:
- Experience with delicate natural fibres, not just everyday laundry.
- Clear communication. A good cleaner asks about stains and checks the label before starting.
- Hand finishing. Quality pressing makes a visible difference to the final result.
- Convenient service. In a city where time is precious, collection and delivery can be a real advantage. Our free collection and delivery across London means your garments are cared for without a trip across town.
- Transparent pricing with no surprises when you collect.
Take pieces in promptly. The sooner a stain is treated, the better the outcome. If you cannot get to a cleaner immediately, cover the stained area with a clean white cloth and keep it away from heat.

Frequently Asked Questions
Can you dry clean silk every time?
Yes, but not constantly. Dry clean when the garment is stained, has been worn several times or is labelled dry clean only. Otherwise, airing it is enough.
Is it safe to put silk in a tumble dryer?
No. Heat and tumbling damage silk’s fibres. Always dry flat or on a padded hanger.
What is the best detergent for silk?
A pH-neutral, enzyme-free detergent made for silk or delicates. Avoid biological powders and fabric softeners.
Can I remove a stain from a silk tie myself?
Blotting gently is fine. For anything more, a professional is the safest choice.
How do I stop cashmere from shrinking?
Wash in cool water, avoid agitation, never wring and always dry it flat.
How often should silk be washed?
Silk does not need to be washed after every wear. Air the garment between uses and wash it when it becomes soiled or develops an odour, following the care label.
Can silk be ironed safely?
Yes. Use the lowest heat setting suitable for silk and iron the garment inside out. A pressing cloth can provide additional protection from direct heat.
How should I store cashmere to prevent damage?
Fold cashmere neatly and store it in a cool, dry place. Avoid hanging it for long periods, as this can stretch the fibres and alter the garment’s shape.
Final Thoughts
Silk and cashmere reward the care you give them. Once you understand how to clean silk clothing properly, you can extend the life of your favourite pieces for years. Keep temperatures low, use gentle products, blot rather than rub and never rush the drying. For ties, scarves, structured garments and anything precious, trust a specialist, because the cost of a professional clean is tiny compared with replacing a luxury item.
