Maintain Engine Cleaner is a hydrocarbon and emulsifier blend, heavy duty cleaner, easily washed away with water after cleaning and degreasing of automotive parts. Applications: For cleaning large parts on site. Allow sufficient time for the product to penetrate the soil. Mechanical assistance with a stiff brush can be helpful. Rinse with water or clean solvent or blow dry. Low pressure spray: Useful where limited access is available. Adequate soaking time should be allowed, which may involve re-application.
