Why Dry Cleaning Changed the Textile Industry Forever
In the absence of today’s dry-cleaning process, delicate clothes posed a significant problem. Clothes made of wool such as suits, clothes made from silk fabric, velvet clothes, leather accessories, and clothes that were embroidered, would always risk damage during washing due to exposure to water. Water was responsible for shrinking clothes, deterioration of natural fibers, and the formation of permanent creases and loss of color.
The need for a cleaning process that would effectively eliminate greases, oils, and other stains without using water led to the emergence of solvent cleaning processes.
Dry cleaning became a great revolution in the cleaning process because it enabled people to clean their expensive clothes without destroying their texture, colors, and other structural characteristics of the clothes.
Understanding the Difference Between Washing and Dry Cleaning
Many people assume that dry cleaning means clothes are cleaned without any liquid. In reality, the term “dry” simply means that water is not the primary cleaning agent.
Traditional washing relies on water combined with detergents to dissolve dirt and remove stains. While effective for cotton and everyday garments, water can damage many delicate materials.
Dry cleaning uses specially formulated liquid solvents instead of water. These solvents dissolve oils, grease, cosmetics, food stains, wax, and other contaminants while minimizing stress on delicate fabrics.
This unique cleaning method helps preserve:
- Fabric texture
- Original garment shape
- Rich colors
- Decorative stitching
- Delicate fibers
- Professional appearance
Because of these advantages, dry cleaning became an essential part of modern garment maintenance.
When Was Dry Cleaning Invented
Probably the most frequent question raised in relation to the laundry industry is about the invention of dry cleaning. The solution to this question goes as far back as the first half of the nineteenth century and involves a very unexpected discovery.
Specifically, in 1825, the owner of a French dye works named Jean Baptiste Jolly observed how the tablecloth got cleaned after kerosene was spilled on it. Instead of spoiling the fabric, the petroleum-based substance washed the grease and dirt off it much better than water.
This discovery encouraged further research into petroleum-based substances to be used for cleaning garments.
The first ever dry cleaning shop opened in France. Cleaners started using such substances as turpentine, gasoline, kerosene, and other petroleum-based liquids to wash the stains off the garments.
Though those solvents performed their function extremely well, they posed considerable risks to people due to the high level of their flammability. Fires and explosions were common phenomena in dry cleaning shops.
Nevertheless, this discovery laid the ground for an entirely new industry which has been developing for two centuries now.
The Earliest Solvents Used in Dry Cleaning
The earliest dry cleaning businesses depended heavily on petroleum-derived liquids because they were effective at dissolving grease-based stains.
Common early solvents included:
- Gasoline
- Benzene
- Kerosene
- Turpentine
- Mineral spirits
- Petroleum naphtha
These liquids removed oils exceptionally well, making them popular among professional garment cleaners.
However, the biggest drawback was safety.
Most petroleum solvents produced highly combustible vapors. Even a small spark from electrical equipment, lighting, or static electricity could trigger devastating fires.
As dry cleaning businesses expanded, governments and safety organizations began encouraging the search for non-flammable alternatives.
This search would eventually lead to one of the most influential developments in dry cleaning history.
What Is Dry Cleaning Solvent
Understanding what is dry cleaning solvent is essential for anyone involved in textile care or commercial laundry operations.
A dry cleaning solvent is a specially formulated liquid designed to remove dirt, grease, oils, stains, cosmetics, body oils, and contaminants without using water as the primary cleaning medium.
Unlike water-based detergents, these solvents penetrate fabric fibers differently. They dissolve oily substances that ordinary washing often struggles to remove.
An effective dry cleaning solvent should possess several important characteristics:
- Strong cleaning ability
- Low fabric damage
- Minimal residue
- Fast evaporation
- Chemical stability
- Safe compatibility with multiple fabric types
- Ability to be filtered and reused
- Reduced odor after cleaning
Modern dry cleaning solvents are carefully selected based on cleaning efficiency, worker safety, environmental regulations, fabric compatibility, and operating costs.
Choosing the right solvent directly affects cleaning quality, garment life, customer satisfaction, and machine performance.
The Evolution from Petroleum Solvents to Safer Alternatives
As the dry cleaning industry expanded during the late nineteenth and early twentieth centuries, safety concerns became increasingly serious.
Petroleum solvents delivered excellent cleaning performance but created dangerous working environments.
Insurance companies, governments, and industry experts recognized the urgent need for safer alternatives that reduced fire hazards while maintaining cleaning efficiency.
Researchers began experimenting with chlorinated hydrocarbons and synthetic chemical compounds that offered improved safety characteristics.
These new solvents dramatically reduced fire risks because they were either non-flammable or significantly less combustible than gasoline and kerosene.
Although early synthetic solvents represented major technological progress, they introduced new challenges involving toxicity, disposal, and environmental impact.
The industry had solved one problem but created another.
This cycle of continuous improvement continues even today.
What Solvent Is Used in Dry Cleaning
People often ask what solvent is used in dry cleaning because modern dry cleaning businesses no longer rely on the same chemicals used hundreds of years ago.
Today’s industry uses several different solvent categories depending on local regulations, environmental standards, business requirements, and garment types.
Common modern solvents include:
Perchloroethylene (PERC)
For decades, PERC became the most widely used dry cleaning solvent because of its exceptional cleaning power and non-flammable nature.
Hydrocarbon Solvents
Hydrocarbon-based cleaners provide gentler fabric treatment while producing less odor than earlier petroleum products.
Silicone-Based Solvents
Silicone cleaning fluids are popular for delicate garments because they clean effectively while remaining gentle on fibers.
Modified Alcohol Solvents
These newer solvents balance cleaning performance with improved environmental characteristics.
Liquid Carbon Dioxide
Some advanced dry cleaning systems use pressurized liquid carbon dioxide as a cleaning medium, offering a more environmentally responsible alternative.
Each solvent has unique advantages and limitations. Selecting the right one depends on cleaning requirements, garment materials, environmental regulations, operating costs, and customer expectations.
The Rise of Chlorinated Solvents
The introduction of chlorinated solvents represented a major milestone in industrial garment cleaning.
Unlike gasoline and kerosene, chlorinated solvents were non-flammable, making workplaces significantly safer.
Dry cleaning businesses rapidly adopted these new chemicals because they reduced fire risks while maintaining high cleaning performance.
This transition also encouraged manufacturers to design more sophisticated dry cleaning machines with improved filtration systems, sealed solvent circulation, and enhanced safety controls.
The industry experienced rapid modernization during this period, paving the way for automated dry cleaning equipment capable of handling larger workloads with greater consistency.
As technology improved, machines became faster, more efficient, and easier to operate, allowing commercial laundries to serve growing urban populations and expanding textile industries.
Perc Dry Cleaning
Along with all the types of solvents that have been introduced over time, perc dry cleaning has been the most influential to the commercial laundry industry. Perc, or perchloroethylene (tetrachloroethylene) became the standard of the industry in the mid-20th century due to its outstanding ability to clean as well as its non-flammability.
Compared to petroleum solvents, PERC was able to efficiently dissolve grease, oil, wax, cosmetics, food stains, and industrial contamination without creating any flammable hazard. It became the preferred option for commercial laundries, hotels, hospitals, textile industries, and dry cleaning businesses that deal with thousands of clothes every day.
PERC also had outstanding cleaning capability, which resulted in shorter processing time and ensured consistent cleaning results. Thousands of dry cleaning machines in the world have been manufactured to work with PERC.
However, as science progressed, the issues of health risks for workers as well as environmental and water pollution became known. Strict laws were enacted in numerous countries, which stimulated businesses to seek more advanced options of technology and safer solvents.
Nowadays, although some places are still using PERC with some control measures, many commercial laundries are trying to switch to more environmentally friendly options of stain removal.
What Chemicals Are Used in Dry Cleaning
Many business owners entering the laundry industry ask what chemicals are used in dry cleaning because cleaning quality depends not only on the machine but also on the chemicals used during the process.
