Many people assume that store-bought cleaners are harmless. A recent scientific paper and regulatory actions show that assumption can be dangerous. New evidence links the solvent perchloroethylene, often called PCE or PERC, to serious liver damage. That raises urgent questions about the products sitting in cabinets and garages.
What researchers found about PCE and liver harm
Scientists published findings that tie PCE exposure to progressive liver scarring. Liver fibrosis can lead to cirrhosis, a life-threatening condition. Public health data ranks cirrhosis among leading causes of death in the United States.

Inhaling PCE vapors or absorbing the chemical through skin poses the main risk. Repeated exposure, even at low levels, increases the chance of long-term damage.
Regulatory changes and product bans you should know
The U.S. Environmental Protection Agency moved to restrict PCE and a similar solvent, trichloroethylene (TCE), in consumer products. The ban targets items like stain removers, adhesives, and some aerosol cleaners.
Officials argued safer formulations are available. Enforcement dates shifted briefly during rule implementation, so some older products may still be in circulation. Do not assume a product purchased before the ban is safe.
How to identify PCE on labels and in your home
Manufacturers may list the chemical under multiple names. Check labels for:
- PCE, PERC, or Perchloroethylene
- Tetrachloroethylene
- Trade names like PerSec or Tetravec
- Chemical registry number 127-18-4
Older cans, bottles, and industrial-style cleaners are more likely to contain solvents. Brake cleaners, metal polishes, and some spot removers can hide PCE inside.
Typical household and automotive products that may contain PCE
PCE has been used widely because it cuts grease quickly. Common applications include:
- Dry-cleaning fluids and spot removers for upholstery
- Brake and parts cleaners for vehicles
- Aerosol paints, sealants, and certain adhesives
- Metal cleaners and polishes
Vapors from these items are the usual exposure route. Skin contact is also possible when you handle liquids without protection.
Practical steps to reduce exposure now
Start by locating any suspect products and reading labels carefully. If you find PCE listed, take action immediately.
- Do not pour PCE products down drains or toss them with household trash.
- Store remaining containers in well-ventilated areas, away from living spaces.
- Contact your local hazardous-waste program for disposal rules.
- Replace PCE items with safer alternatives before you run out.
Safe handling tips
- Wear chemical-resistant gloves when moving older solvents.
- Avoid inhaling fumes; work outdoors or in ventilated garages.
- Keep children and pets far from stored chemicals.
Cleaner options that skip PCE
Many brands now market plant-based and enzyme cleaners that deliver results without harmful solvents. Popular approaches include:
- Concentrated plant-based multipurpose cleaners
- Enzyme stain removers for carpets and upholstery
- Simple pantry solutions like baking soda and vinegar for many jobs
Examples of product types to consider are biodegradable surfactant cleaners and enzyme-based stain treatments. These choices tend to have lower health and environmental risks.
How to choose sustainable cleaning products wisely
When evaluating a product, look beyond buzzwords. Read ingredient lists. Seek third-party certifications if possible. Smaller ingredient lists are often safer.
Prioritize formulations that avoid chlorinated solvents entirely. If a label is vague, contact the manufacturer for a full ingredient disclosure.
