As a textile care and cleaning expert with years of experience in the industry, I have a deep understanding of the processes and materials involved in maintaining the quality and longevity of various fabrics. One of the most critical aspects of professional dry cleaning services is the selection of an appropriate solvent. The solvent plays a pivotal role in the effectiveness and safety of the cleaning process.

Dry cleaning is a sophisticated process that cleans garments without the use of water. The primary cleaning agent in this process is a liquid solvent, which is capable of dissolving dirt and stains without damaging the fabric. Over the years, several solvents have been used in dry cleaning, but one has stood out for its effectiveness and safety profile: perchloroethylene, commonly referred to as PCE.

Perchloroethylene, or PCE, was widely adopted by the dry cleaning industry by the mid-1930s[^3^]. It became the solvent of choice due to its exceptional cleaning capabilities. PCE is particularly adept at removing grease, oil, and wax from fabrics without causing damage, which is why it is compatible with a wide range of garments, including delicate and intricate materials that cannot be cleaned with water.

One of the key advantages of PCE is its nonflammability. This property significantly enhances the safety of the dry cleaning process, especially in a commercial setting where large quantities of solvent are used. Additionally, PCE's chemical stability allows for easy recycling, which contributes to the sustainability of the dry cleaning industry.

However, it is important to note that while PCE has been a mainstay in the industry, there has been growing concern about its environmental and health impacts. PCE is a persistent environmental pollutant and has been identified as a potential human carcinogen[^5^]. As a result, there has been a push towards finding alternative solvents that are safer for both the environment and the workers handling them.

In recent years, the industry has been exploring and adopting alternative solvents that offer similar cleaning power but with reduced environmental and health risks. These alternatives include hydrocarbon-based solvents, silicone-based solvents, and even solvents derived from natural sources like corn.

The transition to safer solvents is part of a broader movement towards sustainability and environmental stewardship within the dry cleaning industry. Companies like ExxonMobil Chemical have developed new solvents, such as DF-2000™, which are designed to be more environmentally friendly and safer for workers[^2^].

In conclusion, while PCE has been the traditional solvent used in dry cleaning due to its cleaning power and stability, the industry is evolving. There is a growing trend towards adopting safer and more sustainable alternatives that minimize environmental impact and protect the health of workers and consumers. As a specialist in this field, I encourage continuous research and development to find the best solutions for the future of textile care.

By the mid-1930s, the dry cleaning industry had adopted tetrachloroethylene (perchloroethylene), or PCE for short, as the solvent. It has excellent cleaning power and is nonflammable and compatible with most garments. Because it is stable, tetrachloroethylene is readily recycled.read more >>
