Silk saree
care guide.

Silk is a protein fibre — chemically similar to hair and fingernails. When it comes into contact with water, the fibres swell unevenly as they absorb moisture, and then contract as they dry. This uneven movement is what causes the sheen to dull, the weave to distort, and watermarks to form — sometimes permanently.

The golden thread (zari) woven into most Banarasi and Kanjivaram sarees is particularly vulnerable. Water oxidises metallic threads, causing them to tarnish from gold to a dull grey that cannot be reversed. Even a small amount of water — from rain, a spill, or an attempted spot clean — is enough to cause visible damage.

Dry cleaning uses chemical solvents that do not cause fibre swelling. The solvent dissolves oils, grease and surface soiling from the fabric, then evaporates completely — leaving the silk undamaged, the sheen intact, and the weave undistorted. It is the only safe cleaning process for all silk varieties.

At The Swiss Laundry, silk sarees are cleaned at a controlled temperature, pressed at a maximum of 110°C with no direct contact, and returned pressed and ready to drape. We have been handling Banarasi, Kanjivaram, Tussar, Chanderi and Jamdani sarees since 2013.

Different silk varieties have different fibre weights, weave structures and embellishments — each with slightly different care requirements. All require dry cleaning. None should be washed.

Understanding the process helps explain why it produces results that home cleaning cannot replicate.

On arrival: The saree is examined under light for existing damage, stains, and areas of fibre weakness. The weave type, fibre content and embellishments are confirmed. A tag is attached with the findings noted — so that no pre-existing damage is attributed to the cleaning process.

Pre-spotting: Each visible stain is treated individually before the cleaning cycle. Oil-based stains (ghee, makeup, skin oil) respond to a solvent pre-spotter. Protein stains (food, sweat) require an enzymatic agent. Water-based stains (tea, cold drinks) are treated with a targeted aqueous agent applied by hand under controlled conditions. This is the most skilled step in the process.

The cleaning cycle: The saree enters the drum with solvent. Cycle time, temperature and agitation are set for silk — a shorter, gentler programme than that used for cotton or wool. The solvent dissolves and carries away oils and particulates. After the cycle, the solvent is extracted and the saree is dried in warm air.

Post-spotting: Any remaining marks are addressed individually after the machine cycle. Some stains — particularly those that have oxidised with age — require additional treatment at this stage. Results are assessed honestly before the saree is pressed.

Steam pressing: The saree is pressed panel by panel using boiler-generated steam at 110°C with no direct contact. The pallu is pressed separately. Pleats are reset. Zari sections are pressed from the reverse side only. The result is a saree that drapes correctly and has the full sheen of its original finish.

The single most important thing to do when a silk saree is stained is to bring it to a dry cleaner as soon as possible. Fresh stains are treatable. Old, set stains are far more difficult — and some are permanent.

At The Swiss Laundry, we assess each stain individually before cleaning begins and advise on likely results before proceeding. Some stains — particularly those more than a year old — may not be fully removable. We will tell you this before we begin.

Incorrect storage is the second most common cause of permanent silk saree damage — after washing at home. A saree stored incorrectly for one season can develop permanent fold marks, insect damage, yellowing and mould that cannot be reversed.

The way a silk saree is pressed determines how well it drapes and how the sheen presents when worn. Incorrect pressing — particularly with a domestic iron — is one of the most common causes of permanent damage.

Temperature: Silk must never be pressed above 110°C. Above this temperature, the protein fibre structure begins to break down and the sheen is permanently destroyed. A domestic iron set to the silk setting is often inaccurate — professional equipment is calibrated precisely.

No direct contact: Silk should never be pressed with a domestic iron directly on the surface. The heat concentration point of an iron, even at the correct temperature, will create a shine mark or scorch on the surface of the fabric. Professional pressing uses steam delivered at a controlled distance or through a pressing cloth, with no contact on the silk surface.

Zari sections: Zari should never be pressed directly. Always turn the saree so the zari work faces down, and press from the reverse side only. Direct pressure on zari flattens the metallic threads and creates permanent indentation marks.

At The Swiss Laundry: All silk sarees are pressed using boiler-generated steam at exactly 110°C. No iron ever contacts the silk surface. The pallu, body and border are pressed separately. Zari sections receive reverse-side steam only. The final result is a saree with restored drape, full sheen, and no press marks.

Kolkata's combination of heat, humidity and seasonal extremes makes silk saree care more demanding than in many other Indian cities. The monsoon brings sustained humidity above 85%, the summer brings temperatures above 40°C, and the winter brings a dry cold that causes static in fine silk. Each season presents different risks.

Monsoon (June–September): The highest-risk period for stored silk. Moisture in the air is absorbed by silk protein fibres — a saree left in a damp room will develop a musty odour within days and surface mould within weeks. Store with silica gel packets. Air the storage area on dry days. Do not store silk directly on a wooden shelf, which absorbs and releases moisture.

Pre-Puja season (September–October): The most important cleaning period. Sarees brought out for Durga Puja should be dry cleaned before wear if they have been stored since the previous season — even if they appear clean. Insects, mould spores and chemical residue from storage can irritate skin and degrade the fabric at the first wearing.

Post-monsoon storage (October–November): Before storing sarees after the festive season, ensure the storage area has dried out completely. The humidity of the previous months may have penetrated the wardrobes and storage boxes. Wipe down storage surfaces, replace silica gel packets, and re-wrap sarees in fresh muslin.

Summer (March–May): High temperatures accelerate chemical reactions in fabric — including the oxidation of food and sweat stains left on stored sarees. A saree stored with an invisible sweat residue will show yellowing at the underarm and drape areas by May. Pre-season cleaning before storage is essential.
