Moderate riskAutomotive cleaning solvents: carb cleaner, brake cleaner, and engine degreaser.
What is this product?
Automotive cleaning solvents: carb cleaner, brake cleaner, and engine degreaser. Methylene chloride (DCM) was historically the primary ingredient — EPA banned in consumer paint strippers (2024) but automotive cleaners are not yet restricted. Current formulations use acetone, toluene, xylene, heptane, or chlorinated alternatives (tetrachloroethylene). All are volatile, flammable (except chlorinated), and neurotoxic with chronic exposure. Aerosol application in enclosed garages creates peak inhalation exposure.
