What is Dry Cleaning? 1

Dry cleansing is a sort of non-aqueous solvent cleansing that uses heated hydrocarbons as its liquid solvent. While not purely “completely dry,” this procedure still utilizes water to efficiently get rid of dust, grime and various other fabrics.

Unlike its name, dry cleansing is anything but “completely dry.” The chemicals employed in this process are very flammable as well as present carcinogen for employees. Thankfully, there are more secure choices to perchloroethylene (PERC).

The History of Dry Cleaning

Dry cleansing as we understand it today began in the late 19th century with Jolly-Belin opening their initial dry cleanser store in Paris in 1840.

Early cleaners utilized lye and also ammonia along with fuller’s planet, a kind of clay to soak up dust. Turpentine spirits (spirits of turpentine) became preferred as an effective spot-cleaner for grease and oil spots.

Legend has it that dry cleaning was initial created in France around 1840 when dye-worker Jean Baptiste Cheerful uncovered just how rapidly kerosene spills on table towel vaporized and also the stains were raised.

In the 1930s, artificial solvents such as perchloroethylene (perc) started replacing petroleum-based cleansers. These nonflammable chemicals provided much better cleaning power and also were much safer to handle; furthermore, PCE required less machines and also flooring area than earlier cleansing solvents, making it more accessible in densely populated areas. With time, both solvent intake and also ecological contamination substantially decreased – especially after advancements in emissions-control innovations were presented.


Perchloroethylene (PERC) is a widely-used solvent in dry cleaning operations. This nonflammable fluid vaporizes swiftly right into air as well as has an ether-like odor when exposed to air.

PERC is extensively used in completely dry cleaning textiles and also steel degreasing operations. In addition, it’s used in making chemicals like paint removers, water repellents, printing inks, adhesives, sealers, as well as gloss.

An additional prominent application of PERC remains in commercial adhesive manufacturing. Though not toxic, it may cause health concerns when subjected to high concentrations in the air.

The New York City State Division of Environmental Preservation regulates alternative solvent dry cleansing machines. These systems must utilize authorized solvents that are reduced in toxicity.

Chlorinated Solvents

After World War I, dry cleansers discovered chlorinated solvents which were much less flammable than petroleum-based solvents as well as had greater cleaning power than their petroleum-based counterparts. Therefore, chlorinated solvents came to be the best choice for several completely dry cleaners.

Nevertheless, these chemicals can leak right into dirt as well as groundwater below dry cleansers, developing environmental contamination problems years after a shop closes. This poses an especially major danger if the soil or groundwater isn’t treated and the chemical does not break down.

Chlorinated solvents are extra efficient and quicker to make use of than hydrocarbons such as kerosene or GreenEarth, but they might have ecological dangers and are managed as contaminateds materials under RCRA (see below). Because of this, many dry cleaners have actually made the switch to hydrocarbon or alternate solvents.

Carbon Dioxide

Carbon dioxide in completely dry cleaning is an efficient method to lessen the dangerous results of petrochemical solvents. This safe gas has outstanding solvating residential properties as well as can be integrated with low concentrations of cleaning up boosters like surfactants or solvents for optimum effectiveness.

It can likewise be used for cleansing steels, polymers, ceramics and glasses. With its effective cleansing capability it properly eliminates a series of pollutants such as grease, paints, fingerprints, oils and contaminated residues.

This process uses pressurized liquid carbon dioxide blended with reduced concentrations of cleaning enhancers to develop a very reliable yet harmless drying service. The carbon dioxide is stirred to move dirt and grease out of clothing, while any type of particulates are eliminated through purification system.

When drying liquid co2, the most affordable stress necessary to keep the temperature level appropriate is important to conserve devices and energy expenses. This may be as reduced as 500 psi (35.2 Kg/cm2). Greater temperature levels and also pressures are offered too.
