Cleaners & Additives encompass a range of fluid and chemical treatments for vehicle systems including fuel, cooling, braking, and lubrication. These products are applied throughout the engine, drivetrain, and ancillary systems to remove contaminants, restore performance, or enhance fluid properties. Technical features include specialized solvent blends for dissolving deposits, friction modifiers for optimized lubrication, corrosion inhibitors for component protection, and detergents for maintaining system cleanliness. Formulations vary by application, addressing specific issues like injector fouling, scale buildup, or oil sludge. Proper use, following manufacturer instructions, is critical to avoid component damage or system malfunction.
