High-Performance Carbon Deposit Remover for Gas Engines

Restore engine performance and fuel efficiency with WD-40 Specialist® Carb & Throttle Body Cleaner—the ultimate all-in-one cleaning solution for carburetors, throttle bodies, and unpainted metal engine parts. This 13.5oz aerosol features an attachable precision straw and a powerful dual-action cleaning system: solvents break down tough, baked-on carbon deposits, while the high-pressure spray blasts away residue without leaving behind any film.
