Silk Care · The Complete Answer · The Swiss Laundry
\nCan you wash silk at home?
\nThe short answer: some silk can be carefully hand-washed. Most Indian silk — sarees, Banarasi, Kanjivaram, embroidered occasion wear — cannot. Here is the complete breakdown by silk type.
\n \nSome lightweight plain silk can be carefully hand-washed in cold water. Silk sarees, Banarasi, Kanjivaram, embroidered silk and any structured silk garment — dry clean only. The risk with water is permanent loss of sheen, watermarks and zari tarnishing.
\n The Swiss Laundry · Kasba, Kolkata · Est. 2013\nWhy silk and water are complicated: Silk is a protein fibre with a triangular cross-section that reflects light — this is what creates the sheen. Water causes the protein surface to denature slightly, scattering light rather than reflecting it. The sheen dulls permanently. On heavy silk like Banarasi or Kanjivaram, this change is immediate and irreversible.
\nSilk by type — can it be washed?
\n| Silk type | Washable? | Why |
|---|---|---|
| Plain silk shirt / blouse (lightweight) | With extreme care | Cold water only, pH-neutral detergent, no agitation. Lay flat to dry. High risk of watermarks. |
| Banarasi silk saree | No — dry clean only | Heavy silk + zari. Water dulls the silk and tarnishes the metallic thread immediately. |
| Kanjivaram saree | No — dry clean only | Dense weave and heavy zari. Any water contact risks permanent damage to both components. |
| Tussar silk | No — dry clean only | Raw silk surface is particularly vulnerable to watermarks. |
| Chanderi (silk-cotton) | No — dry clean only | Combination fabric reacts unevenly to water, causing distortion. |
| Silk velvet | No — dry clean only | Water collapses the pile permanently. Irreversible. |
| Embroidered silk | No — dry clean only | Embroidery threads — particularly metallic — are separately damaged by water. |
| Silk dupatta (plain, lightweight) | With extreme care | Very cold water, no agitation, lay flat. Still carries risk of watermarks. |
If washing silk at home — the correct method
\nThis applies only to plain, lightweight silk with no embellishment, lining or metallic thread. For all other silk — dry clean.
\nWater temperature: Cold. Never warm, never hot. Heat accelerates the protein denaturing that dulls the sheen.
\nDetergent: A pH-neutral silk wash or specialist delicate detergent. Regular detergent, fabric softener and biological (enzyme) detergents all damage silk fibres.
\nMethod: Soak for maximum 5 minutes. Move the fabric gently — do not rub, wring or agitate. Rinse in cold water until no detergent remains. Squeeze gently — press water out, never wring.
\nDrying: Lay flat on a clean dry towel in shade. Never tumble dry, never hang in direct sunlight. UV bleaches silk dyes and weakens fibres.
\nPressing: Iron from the reverse side while still slightly damp, at the silk/low setting. Never press directly on the face of the fabric at high heat — it creates permanent shine marks.
\nWhat dry cleaning does that washing cannot
\nDry cleaning removes the water risk entirely. The chemical solvent used in dry cleaning is non-polar — it dissolves oils and residues without contacting the silk protein surface. The sheen is preserved. The zari is not wetted. The structure is not disturbed.
\nAfter dry cleaning, all silk garments are pressed with boiler steam at 110°C without direct iron contact — this restores the natural drape without the risk of shine marks from a domestic iron.
\n \nCommon questions
\nQuestions.
Answered.
\n Some lightweight plain silk can be carefully hand-washed in cold water with a pH-neutral silk wash. Silk sarees, Banarasi, Kanjivaram, embroidered silk and any structured silk must be dry cleaned. When in doubt, dry clean.
The protein surface denatures slightly, scattering light and dulling the sheen permanently. The fabric may also distort unevenly as it dries. Metallic threads (zari) tarnish on contact with water.
Cold water only. pH-neutral silk detergent. Maximum 5 minutes soak. No agitation, no wringing. Press water out gently. Lay flat to dry in shade. Iron from the reverse side while slightly damp at the silk setting.
No. Silk sarees — Banarasi, Kanjivaram, Tussar, Chanderi — should always be dry cleaned. The silk construction and metallic zari are both permanently damaged by water.
Do not apply water. Do not rub. Blot excess with a completely dry cloth only. Bring to a professional dry cleaner as soon as possible and tell them what the stain is. Fresh stains on silk are usually fully removable.
