Yes, it is. AMSOIL cleaner comprises chlorinated solvents, specifically perchloroethylene. These solvents are non-flammable and fast-drying, offering superior cleaning properties for brake and automotive parts. Unlike non-chlorinated solvents, which can vary in dry time based on their volatile organic compound (VOC) content, our product contains zero VOC content. Many states regulate VOC levels and place restrictions on where they can be used and sold, including regulations on chlorinated brake cleaners (e.g., California, New Jersey and Canada).
