The Decline of Dry Cleaners in the United States and the Shift Towards Green Cleaning Methods
TLDR Dry cleaners in the United States, often owned by people of Korean descent or Korean immigrants, are facing financial pressure and small business struggles due to the decline in demand for dry cleaning services. The industry has been further impacted by the negative health effects of the go-to solvent, perchloroethylene, leading to a shift towards more environmentally-friendly cleaning methods.
Timestamped Summary
00:00
Dry cleaners in the United States have been struggling for a while, with the pandemic exacerbating the decline in business due to people working from home and dressing more casually, resulting in a decrease in the need for dry cleaning services.
05:02
Dry cleaners in the United States, often owned by people of Korean descent or Korean immigrants, are facing financial pressure and small business struggles, with the process of dry cleaning itself being a misnomer as it does not involve water.
10:09
Dry cleaning originally used dangerous and flammable solvents like kerosene and gasoline, but eventually switched to synthetic compounds like carbon tetrachloride and trichloroethylene, which had their own problems, before settling on perchloroethylene or "perk" as the go-to solvent, despite its negative health effects.
15:17
Dry cleaning involves inspecting clothes for stains, pretreating them if necessary, and then using an industrial synthetic solvent called "perk" to soak the clothes, despite the process being called "dry" cleaning.
20:51
Dry cleaning machines are dry-to-dry machines that use a solvent called "perk" to wash and dry clothes in the same drum, with the perk being recovered and reused in a closed system.
25:54
Dry cleaners rely on human inspection and post-cleaning spot removal to ensure that stains are properly treated and removed, using specific solvents depending on the type of stain.
30:38
Dry cleaning is a more gentle and delicate process compared to traditional washing because it uses solvents that do not penetrate the fabric and cause shrinking, making it suitable for delicate and shrinkable fabrics.
35:27
The hosts discuss the wear and tear that occurs on clothes during the washing and drying process at home, and mention that they sometimes used to have someone else do their laundry.
40:31
Dry cleaners in the United States and Europe still use Perk, a neurotoxin and carcinogen that has caused environmental contamination and health issues, leading to regulations and clean-up requirements for dry cleaning facilities.
46:01
Dry cleaning sites are often contaminated and require expensive cleanup, even if the contamination occurred before the current owner took over, and the damage extends to aquatic creatures; however, there is a shift towards green dry cleaning methods, such as wet cleaning and liquid CO2 cleaning, although these alternatives can be costly.
51:10
There are different types of solvents used in dry cleaning, including hydrocarbon solvents like DF2000, which is produced by ExxonMobil, and silicon-based solvents like liquid silicone used by Green Earth, but the environmental impact and toxicity of these solvents is still a subject of debate.
56:29
Marie Thart faced challenges and was initially dismissed in her work, but she persisted and eventually gained recognition for her ideas.
