Health & Environmental Concerns:
-
Toxic if inhaled in large amounts or over time (linked to liver, kidney, and nervous system effects)
-
Classified as a possible human carcinogen
-
Requires well-ventilated, sealed systems and PPE for operators
-
Strictly regulated in many countries (e.g., banned or phased out in California, EU restrictions)
Alternatives to PERC in Modern Dry Cleaning:
-
Hydrocarbon solvents (less aggressive, more eco-friendly)
-
Liquid CO₂ cleaning
-
Siloxane-based solvents (e.g., GreenEarth®)
-
Professional wet cleaning (water-based with special machines and detergents)
Conclusion:
Perchloroethylene remains effective but is increasingly being replaced due to safety and environmental concerns. Dry cleaners using PERC must comply with strict safety protocols and environmental regulations.
