What’s dry cleaning and just how do you use it?

Dry cleaning is a specialized cleaning process that cleans clothing without using water. Despite its name, the process isn’t completely dry as it utilizes chemical solvents instead of water.

The History of Dry Cleaning

The origins of dry cleaning date back to the 1840s in Paris, when an accidental discovery occurred. A petroleum-based fluid was spilled on greasy fabric, and as it evaporated, the stains miraculously disappeared. The firm Jolly-Belin is credited as being the first professional dry cleaning company.

Dry Cleaning Solvents

Historically, various flammable fluids were used as dry cleaning solvents, including:

• Camphene
• Benzene
• Kerosene
• Gasoline

These hazardous materials made dry cleaning a dangerous business until safer alternatives were developed.

In the 1930s, percholoroethylene (commonly called “perc”) was introduced and remains widely used today in many dry cleaning facilities. This solvent proved to be both safer and more effective. Modern alternatives include hydrocarbon-based solvents and environmentally-friendly options like Green Earth, with new solvents continually being developed and tested.

How Dry Cleaning Machines Work

A dry cleaning machine combines functions similar to both a washer and dryer, but on a larger scale. The process involves:

1. Loading clothes into the machine
2. Adding solvent gradually to lift and remove soil
3. Draining the solvent after the cleaning cycle
4. Extracting remaining solvent through a spin cycle
5. Drying with heated air to vaporize any residual solvent

The result is clean clothing without water damage or solvent residue.

Now you understand the science behind this “magical” cleaning process that keeps your delicate garments looking their best.
