Methylene chloride

Overview

Methylene chloride (MC) is a colorless liquid that has a sweet odor. It is used as paint and varnish remover, a solvent, and a degreaser. Methylene chloride is dangerous. It can severely burn your skin and eyes. It can also damage your liver, kidneys, and brain. You are exposed when you breathe the vapors or get methylene chloride on your skin. Although it has an odor, you may not be aware of it.

Breathing methylene chloride irritates your nose, throat, and lungs. It can cause headaches, nausea, dizziness, and weakness. Severe overexposure can kill you. Bathtub and tile refinishers who use methylene chloride-based products should be especially careful to reduce their exposure and protect themselves.
