Dry-cleaned clothing — safety profile
High riskClothing and textiles labeled 'dry clean only' that are processed at commercial dry cleaning facilities using chlorinated solvent systems.
What is this product?
Clothing and textiles labeled 'dry clean only' that are processed at commercial dry cleaning facilities using chlorinated solvent systems. The dominant dry cleaning solvent historically and currently is perchloroethylene (PERC / tetrachloroethylene) — IARC Group 2A (probable human carcinogen), a potent kidney and liver toxicant, and a persistent groundwater contaminant. PERC-dry-cleaned garments returned to the consumer retain PERC residues that off-gas in enclosed spaces (closets, cars) and are inhaled. Proximity to dry cleaning facilities is a documented environmental justice concern — residential buildings above or adjacent to PERC dry cleaners have significantly elevated indoor PERC.

Compounds of concern
Who's most at risk
- Children — Thinner skin, higher dermal absorption, mouthing of clothing
How to use it more safely
- Ensure adequate ventilation before wearing dry-cleaned items
- Allow garments to air out for 24-48 hours after pickup
- Wear in well-ventilated spaces to minimize solvent exposure
- Follow garment care labels and manufacturer instructions
Red flags — when to walk away
- Fresh dry-cleaned garments brought directly into the bedroom in the plastic bag — The plastic bag traps PERC vapors. Opening it in an enclosed bedroom and leaving clothes on the rack creates a high indoor PERC concentration episode.
- Pregnancy and regular dry cleaning use — PERC crosses the placenta and is found in amniotic fluid at concentrations proportional to maternal exposure. Fetal PERC exposure is associated with adverse developmental outcomes in epidemiological studies.
- Apartment directly above or adjacent to a dry cleaning operation — PERC migrates through building structures and ventilation. EPA has documented residential PERC concentrations in units above dry cleaners at levels requiring remediation action.
Green flags — what to look for
- Dry cleaner advertising 'wet cleaning' or 'PERC-free' process — Wet cleaning is the EPA-preferred alternative. PERC-free dry cleaners exist in most cities; finding one eliminates garment PERC residue exposure.
Safer alternatives
- Wet cleaning — Water-based cleaning method eliminates toxic solvent exposure
- Home washing — Safe for most fabrics when following care labels
- Green/organic dry cleaning — Uses biodegradable solvents with lower toxicity profiles
