Engine Cleaner

Engine

Dissolves and removes external grease, oil, and carbon deposits from engine surfaces and fuel system components.

Engine cleaner is typically a spray-on or foaming aerosol product applied directly to engine surfaces, intake valves, and fuel injectors to remove oily residue, carbon buildup, and dirt. Some formulations are added to the fuel tank to clean fuel injectors and intake systems. These products improve appearance and can help restore performance by removing deposits from critical areas.
