When people ask, “Who invented dry cleaning?” The answer is often surprising.
Many industry histories point to French businessman Jean Baptiste Jolly and his accidental discovery in the 1820s. But the person who actually patented a water-free garment cleaning process was Thomas L. Jennings, a New York tailor and inventor.
His innovation not only helped shape the modern dry cleaning industry but also earned him a place in American history as the first African American to receive a U.S. patent.
Here’s how dry cleaning evolved from ancient stain removal methods into the industry we know today.
Quick Answer
Who Invented Dry Cleaning?
- Thomas L. Jennings patented the first known dry cleaning process (“dry scouring”) in 1821.
- Jennings was the first African American to receive any U.S. patent.
- Jean Baptiste Jolly popularized modern dry cleaning in France a few years later.
- Modern dry cleaning evolved from these early solvent-based cleaning methods.
The Earliest Forms of Dry Cleaning
Long before modern dry-cleaning machines existed, people searched for ways to clean delicate garments without traditional washing.
In ancient Rome, professional cleaners known as fullers used substances such as ammonia and lye to remove dirt, oils, and stains from clothing. While effective for the time, these methods were labor-intensive and often harsh on fabrics.
These early techniques laid the foundation for what would eventually become modern dry cleaning: cleaning garments without immersing them in water.
Jean Baptiste Jolly and the Birth of Modern Dry Cleaning
One of the most famous stories in dry cleaning history involves Jean Baptiste Jolly, a French dye-works owner.
Around 1825, a maid reportedly spilled turpentine on a stained tablecloth. After the solvent evaporated, Jolly noticed the stained area looked cleaner than the rest of the fabric. Curious, he experimented further and discovered that certain solvents could remove stains without damaging delicate textiles.
This discovery led him to open one of the first commercial dry cleaning businesses in Paris and helped popularize solvent-based garment cleaning.
While Jolly helped bring dry cleaning into the mainstream, he wasn’t actually the first person to develop the process.
Thomas L. Jennings: The True Inventor of Dry Cleaning
Several years before Jolly’s discovery, Thomas L. Jennings had already been working to solve a common problem.
As a tailor and clothier in New York City, Jennings regularly encountered garments made from delicate fabrics that could not withstand traditional washing methods. Customers needed a way to remove stains without ruining expensive clothing.
Through extensive experimentation, Jennings developed a process he called “dry scouring.” Instead of relying on water, his method used specialized cleaning agents to remove dirt and stains from fabrics.
In 1821, Jennings received a U.S. patent for his invention—making him:
- The first African American to receive a U.S. patent
- One of the earliest innovators of solvent-based garment cleaning
- A foundational figure in the history of dry cleaning
His invention established many of the core principles that still define dry cleaning today.

How Dry Cleaning Solvents Evolved
Early dry cleaning methods were effective, but they came with significant safety concerns.
During the 19th century, cleaners commonly used solvents such as:
- Turpentine
- Kerosene
- Benzene
- Gasoline
- Petroleum-based products
While these substances removed stains well, they were highly flammable and created serious fire risks for dry cleaning businesses.
As the industry matured, safer alternatives emerged.
The Rise of Chlorinated Solvents
In the early 1900s, chlorinated solvents gained popularity because they were nonflammable and more practical for commercial operations.
By the 1930s, perchloroethylene (perc) became the industry’s preferred solvent. Perc offered strong cleaning performance while reducing many of the safety risks associated with earlier chemicals.
Over time, the industry has continued exploring additional cleaning methods, including:
- Hydrocarbon solvents
- Silicone-based cleaning solutions
- Professional wet cleaning systems
- Environmentally focused alternatives
Today’s dry cleaning businesses have more options than ever when choosing cleaning technologies that align with their operational and environmental goals.
How Technology Has Transformed Dry Cleaning
The biggest changes in dry cleaning over the last few decades haven’t just happened inside the machine.
Modern dry cleaning businesses rely heavily on technology to improve efficiency, customer service, and profitability.
Today’s leading cleaners use software to:
- Manage customer information and preferences
- Track garments throughout production
- Automate pickup and delivery operations
- Process payments and subscriptions
- Communicate with customers through text and email
- Monitor business performance with real-time reporting
For growing dry cleaning businesses, technology has become just as important as the cleaning process itself.
In recent years, many dry cleaners have expanded beyond traditional garment care by offering pickup and delivery services, automated customer communications, subscription programs, and digital customer experiences. These innovations help cleaners meet changing customer expectations while improving operational efficiency.
What Dry Cleaners Can Learn from Thomas L. Jennings
Thomas L. Jennings succeeded because he recognized a problem and found a better solution.
That same mindset continues to drive successful dry cleaning businesses today.
Whether it’s adopting modern cleaning methods, streamlining operations, improving customer communication, or expanding pickup and delivery services, the most successful cleaners are constantly looking for ways to innovate and improve the customer experience.
The industry has evolved dramatically since 1821, but the principle remains the same: businesses that embrace innovation are best positioned for long-term growth.
