The dry cleaning industry has a rich history of evolution, particularly in its choice of solvents. Initially, flammable petroleum-based solvents like kerosene and Stoddard solvent were used, but safety concerns and a desire for improved cleaning performance led to a significant shift. The introduction of chlorinated solvents, such as carbon tetrachloride and trichloroethylene (TCE), marked a new era, offering better stain removal and reduced flammability. However, it was the advent of tetrachloroethylene (PCE) in the 1930s that truly revolutionized the industry.

Tetrachloroethylene quickly became the dominant dry cleaning solvent due to its ideal combination of properties: excellent solvency for common garment stains, non-flammability, stability for effective recycling, and a relatively mild odor. For decades, PCE served as the benchmark for effective garment care, allowing for the cleaning of delicate and sensitive fabrics that would be damaged by water. Its widespread availability and economic efficiency further cemented its status as the industry standard. Businesses could rely on the consistent performance of tetrachloroethylene to deliver high-quality cleaning results.

Today, the industry is again at a crossroads, driven by increasing awareness of the environmental and health impacts associated with PCE. While still widely used, there is a significant push towards alternative solvents and cleaning technologies. Hydrocarbon solvents, silicone-based solvents, and advanced wet cleaning systems are emerging as viable replacements. These alternatives aim to provide comparable cleaning efficacy while offering improved safety profiles and reduced environmental footprints. The ongoing research and development in this area are paving the way for a more sustainable future in garment care, moving beyond the era of tetrachloroethylene towards innovative solutions that benefit both consumers and the planet. The story of dry cleaning solvents is one of continuous adaptation and innovation, ensuring that clothing care remains effective and responsible.
