Dry Cleaning is a simple process that cleans clothing without the use of water. However, despite its name, the process is not completely dry. Fluids are used in the dry cleaning process.
Dating back to the 1840’s in Paris, there was a surprise discovery when a petroleum-type fluid was accidentally spilled on a greasy fabric. It quickly evaporated and the stains were miraculously removed. The firm of Jolly-Belin is credited as the first dry cleaning firm.
Solvents
In the early days, several fluids were used as dry cleaning solvents, including camphene, benzene, kerosene, and gasoline. These fluids are dangerously flammable, dry cleaning was considered a hazardous business until safer solvents were developed.
In the 1930’s, percholoroethylene, or perc for short, was introduced and is used today in many dry cleaning plants. It proved to be safer and clean better. Other cleaning solvents have been added, including hydrocarbon, Green Earth, and others that are currently being introduced and tested.
Machines
A dry cleaning machine is similar to a combination washer and dryer, only larger. The clothing is loaded into these machines and the solvent is gradually added to lift and flush away the soil. After the cleaning cycle, the solvent is drained and extracted through a spin cycle. Once the clothes are finished extracting, the drying process begins. Warm air circulates through the machine vaporizing the solvent left on the clothes. When finished there is no remaining residue or solvent odor.
Now you have a better understanding of this “magical process’ of dry cleaning.
I've delved into the intricacies of dry cleaning, and it's more than just a process—it's a fascinating journey through time and chemistry. The historical roots trace back to 1840s Paris, where a serendipitous spill of a petroleum-type fluid on greasy fabric led to the discovery of a stain-removing miracle. Jolly-Belin, credited as the pioneers, laid the foundation for what would become the dry cleaning industry.
Early on, dry cleaning relied on a perilous mix of solvents, including camphene, benzene, kerosene, and gasoline. The risks posed by these highly flammable substances made dry cleaning a hazardous endeavor. Enter the 1930s, and the game-changing solvent, perchloroethylene (perc), stepped in. Its safety and superior cleaning abilities revolutionized the industry, gradually making dry cleaning a more secure practice.
The solvent lineup has expanded since then, with alternatives like hydrocarbon, Green Earth, and various experimental options. These solvents undergo rigorous testing to ensure both efficacy and safety, pushing the boundaries of what dry cleaning can achieve.
The machines themselves are marvels of engineering, resembling oversized combination washer-dryers. Clothes are loaded into these machines, and the solvent is delicately introduced to lift and flush away the dirt. A meticulous process follows: draining and extracting the solvent through a spin cycle. The drying stage kicks in, with warm air circulating to vaporize any remaining solvent. The end result is clothes free of residue and any lingering solvent odors.
Now, armed with this knowledge, the seemingly magical process of dry cleaning unravels into a sophisticated interplay of history, chemistry, and cutting-edge technology.
Machine dry cleaning – Our professionals will load your clothes into a large drum machine with liquid solvents. The machine will agitate your garments in a similar fashion to your washing machine at home. This removes dirt, oil, and stains. Finishing – We complete the process by ensuring your clothes are ready to wear.
With dry cleaning, the solvent-based cleaning agents used will effectively remove stains without the need for high temperatures or vigorous mechanical action, both of which can compromise the structure of delicate fibers.
Whether or not dry cleaning is more effective than washing really depends on the garment we are washing. For oil-based stains, yes, dry cleaning is more effective than washing. For clothes that have an odour, especially items with body odour from perspiration, washing will be much more effective than dry cleaning.
In terms of mechanism, dry cleaning selectively solubilizes stains on the article. The solvents are non-polar and tend to selectively extract many compounds that cause stains. These stains would otherwise only dissolve in aqueous detergent mixtures at high temperatures, potentially damaging delicate fabrics.
Dry cleaning may not be as effective as regular washing when it comes to removing the stench from your everyday clothes. If the clothing you dry-cleaned still smells of sweat, perfume, or smoke after you get it back, then you might need to take some extra steps to remove the odours.
Some articles of clothing still require professional cleaning. However, for most dry-clean-only clothes, it's easy to dry clean at home using the right methods. Use this simple guide for dry cleaning at home with a kit or using homemade cleaners.
Yes, dry cleaning can remove a variety of stains because it uses specialized solvents instead of water. This process is more gentle on delicate fabrics but stronger against stains, extending the life of your clothing and preserving its shape without the risk of shrinkage.
The source of smelly dry cleaning can be traced to a chemical called perchloroethylene, otherwise referred to as “perc.” Perc is a laundering solvent that has been used in dry cleaning since the 1940s and is still the most commonly found chemical in traditional dry cleaning businesses.
Typical fabrics that cannot be dry cleaned safely include fabrics containing or made up of plastic, PVC, or polyurethane. Fabrics composed of these materials would deteriorate during the cleaning process.
However, dry cleaning has some drawbacks. It is often more expensive than wet cleaning, uses many hazardous solvents, is not considered sustainable, and may not completely remove certain types of stains, as well as not removing odors.
Dry clean only clothes should not be washed in a regular washing machine as it can cause shrinkage, color bleeding, and fabric distortion. Ignoring the dry clean only instructions can lead to costly consequences such as damage that may require expensive repairs or replacement of the garment.
When clothes are cleaned at the dry cleaners they're put into an appliance that looks similar to a washing machine (it's actually a washer-extractor-dryer) but instead of using water and detergent it uses a liquid solvent such as perchlorethylene.
Dry cleaning is a process of cleaning clothes using a chemical solvent instead of water. The most common solvent employed is Perchloroethylene (also known as Tetrachloroethylene), or "Perc" for short. The chemicals are toxic and inflammable.
After the cleaning cycle, the clothes are dried and pressed to remove any remaining solvent and to give them a fresh, clean look. The solvent used in the dry-cleaning process is then filtered and recycled to be used again, making it a more sustainable option compared to traditional laundry methods.
