Methylene Chloride, also known as dichloromethane or DCM, is a solvent used in a range of products. The average consumer is most likely to encounter it in paint strippers, even though safer alternatives exist. Methylene Chloride has been linked to cancer, cognitive impairment, and asphyxiation.

Numerous people have died from exposure to Methylene Chloride. In 2017, the U.S. Environmental Protection Agency (EPA) proposed to ban this chemical’s use in paint stripping. In 2019, EPA only finalized the ban on consumer uses and sales, leaving workers unprotected. In 2021, the agency withdrew the part of the proposed rule that would have protected workers. We’re calling on retailers to take action and stop selling paint strippers containing Methylene Chloride. In the meantime, if you need to remove paint or a coating, make sure to avoid Methylene Chloride and other toxic chemicals like N-methyl pyrrolidone (NMP).

What products contain Methylene Chloride?

Paint Strippers: Methylene Chloride is a key ingredient in a variety of paint strippers sold in the U.S.

Adhesives: This chemical is also used in a range of adhesives, such as acrylic cement for hobbyists. For a comprehensive list of adhesives containing Methylene Chloride, click here to view the list developed by EPA in February 2017 (see pages 7-10)

Other Products: Other products containing DCM are used for automotive care, lubrication, lithography, and general cleaning. Review EPA’s comprehensive list here.

How am I exposed to this chemical?

If you are a consumer or worker who uses products with Methylene Chloride, you may be exposed by inhaling the fumes of the chemical. It’s also possible for this chemical to be absorbed through skin.

How can I avoid exposure to Methylene Chloride?

Know the ingredients in your paint stripper or other products listed above

If you or your home contractor needs to remove paint or a coating, make sure the product used does not contain Methylene Chloride. Methylene Chloride has killed a wide range of people from workers to those conducting “do-it-yourself” projects.

Even if you are in a different room while the work is going on – or if the work was completed in a poorly ventilated room and you use it just a few hours after the project – you may still be at risk of developing health problems from the fumes.

Companies have commonly substituted Methylene Chloride with another toxic chemical: N-methylpyrrolidone (NMP). It’s also important to avoid products.
