Engine cleaner is a specialized cleaning product designed to remove dirt, grease, and grime from the engine compartment of vehicles. It helps maintain the engine's performance by ensuring that components are free from contaminants that can cause overheating or corrosion. Engine cleaners come in various forms, including sprays and foams, and are typically safe for use on metal and plastic surfaces. Using an engine cleaner can also improve the overall appearance of the engine bay, making it easier to spot potential issues. Regular cleaning can extend the life of engine components and enhance the resale value of the vehicle. Always follow the manufacturer's instructions for best results and safety precautions.
