Green Dry Cleaning Alternatives Available in India

Why Alternatives to Perc Are Being Developed

Perchloroethylene is classified as a Group 1 carcinogen by the International Agency for Research on Cancer — meaning there is sufficient evidence that it causes cancer in humans. This classification is based primarily on studies of occupational exposure among dry cleaning workers, who are exposed at concentrations and durations far exceeding those of customers. For occasional dry cleaning customers, the residual exposure from freshly cleaned garments is at much lower concentrations.

Nevertheless, the classification has driven regulatory action in Europe, the United States, and several Asian markets. California, for instance, has mandated a complete phase-out of perc from dry cleaning operations. The European Union has established strict exposure limits for workers in perc-using facilities. These regulatory pressures have accelerated the development of alternative solvents and cleaning systems that are now commercially available globally and in a limited number of Indian facilities.

Wet Cleaning — The Most Established Alternative

Professional wet cleaning is the most commercially developed alternative to perc dry cleaning and is available in India, primarily in organised dry cleaning chains in major cities.

Despite the name, professional wet cleaning is not the same as home machine washing. It uses water as the cleaning medium, but with several critical differences from home washing:

Specialist detergents formulated specifically for protein fibres and delicate fabrics — pH-neutral, low-alkalinity formulations that clean effectively without the alkaline damage risk of standard laundry detergent.

Computer-controlled machines that regulate water temperature, mechanical action, and spin speed with precision that home machines cannot achieve. The gentle mechanical action profiles prevent the agitation that causes wool felting and silk distortion.

Controlled drying using professional equipment that restores fabric dimensions and shape as the garment dries, counteracting the shrinkage and distortion risk of uncontrolled air drying.

Expert finishing — professional pressing and reshaping that restores the garment's original appearance.

The combination of these elements means that professional wet cleaning can successfully clean many garments traditionally sent to perc dry cleaners — including many wools, silks, and structured garments — without using any chemical solvent.

Professional wet cleaning is not appropriate for all garments. Heavily embellished occasion wear, velvet, and garments with very specific structural requirements may still need solvent cleaning. But the range of garments that professional wet cleaning can handle has expanded significantly with the development of specialist detergents and equipment.

In India, professional wet cleaning is available in select facilities associated with national dry cleaning chains in cities including Delhi, Mumbai, Bengaluru, Chennai, and Hyderabad. Availability varies significantly — calling ahead to confirm whether a specific facility offers wet cleaning is advisable.

Hydrocarbon Solvents — A Lower-Risk Solvent Alternative

Hydrocarbon solvents — typically marketed under trade names like DF-2000, EcoSolv, or Shell Sol — are petroleum-derived solvents used as perc alternatives in dry cleaning machines. They function similarly to perc in the cleaning process but have a significantly different health and regulatory profile.

Hydrocarbon solvents are not classified as carcinogens. They are flammable, which requires specific safety infrastructure in facilities using them, and they are not fully biodegradable. They also clean somewhat less aggressively than perc — which means they are highly effective on general soiling but may be less effective on very heavily soiled items.

For most household garments sent to the dry cleaner — business suits, formal wear, delicate blouses, structured jackets — hydrocarbon solvents perform comparably to perc and represent a meaningfully lower health and environmental risk.

Hydrocarbon solvent facilities are more common in India than liquid CO2 facilities but still represent a minority of dry cleaning operations. The absence of a distinctive chemical odour in the facility or on returned garments is one indicator — perc has a characteristic sharp solvent smell that hydrocarbon solvents lack in the same way.

Liquid CO2 Cleaning — The Lowest-Impact Option

Liquid CO2 cleaning uses pressurised carbon dioxide as the cleaning solvent. At pressures above 60 bar, CO2 becomes a liquid that can dissolve oils and many types of soil from fabric. After cleaning, the pressure is released, the CO2 returns to a gas state, and no chemical residue remains on the garment.

The environmental and health profile of liquid CO2 cleaning is the best of any current commercial dry cleaning method. The CO2 used is captured from industrial processes and reused, meaning the system does not add net carbon to the atmosphere. No chemical solvent residue is left on garments. No hazardous waste is generated.

The constraints are the equipment cost — liquid CO2 cleaning systems require substantial investment in pressurised vessels and related infrastructure — and the fact that CO2 is a less effective degreaser than perc, meaning it works best on lightly to moderately soiled garments.

In India, liquid CO2 cleaning is rare but not absent. A small number of premium dry cleaning facilities in Bengaluru, Mumbai, and Delhi have invested in CO2 systems, typically as a differentiating service for high-value garments.

Silicone-Based Solvents

Silicone-based solvents — sold under trade names including GreenEarth — use a liquid silicone compound (decamethylcyclopentasiloxane, or D5) as the cleaning solvent. The silicone is gentle on fibres, leaves no residue, and breaks down in the environment into silica, water, and carbon dioxide.

Silicone solvents are particularly gentle on delicate fabrics and are considered appropriate for silk, lace, and other fine textiles. They are less effective on heavy grease and oil-based soiling than perc.

Silicone-based cleaning is available in a small number of premium facilities in major Indian cities, often marketed as a specialist option for delicate and luxury garments.

How to Find Alternatives in Your City

The simplest approach is to ask directly when calling a dry cleaner: "What solvent do you use for dry cleaning?" A facility using an alternative to perc will generally be willing — often proud — to say so. A facility that cannot or will not answer this question is almost certainly using perc.

Larger organised dry cleaning chains in Indian cities are more likely to have invested in alternative cleaning systems than small independent neighbourhood shops, where perc remains the overwhelming norm.
