Carburetor & Throttle Body Cleaners

Carburetor cleaner is formulated to remove varnish, gum, and carbon deposits from carburetor jets and passages; throttle body cleaner is tuned to dissolve buildup on throttle plates and electronic sensors without leaving residue. Choose based on the part you're servicing—use carburetor cleaner for older carburetors and throttle body cleaner for throttle bodies and intake components on fuel-injected engines

Check the product label for compatibility with your fuel system (carbureted vs. fuel-injected), materials (aluminum, rubber, plastic, sensor-safe), and intended use (spray-can for spot cleaning vs. bulk for shop use). Prioritize formulas marked sensor-safe or non-corrosive if you’ll clean electronic throttle bodies or O2 sensor-proximate areas

Yes—use in a well-ventilated area, avoid inhaling fumes, wear gloves and safety glasses, and keep away from open flames because most formulas are flammable. Follow the product's SDS for first aid and spill instructions

Some solvents can damage soft plastics, rubber, sensor coatings, and paint; look for products labeled safe for electronics, O-rings, and painted surfaces, and avoid prolonged contact. When in doubt, test on a small inconspicuous area or consult the vehicle manufacturer’s service guidance

Frequency depends on driving conditions and symptoms, but routine cleaning every 30,000–60,000 miles or when you notice rough idle, stalling, poor throttle response, or decreased fuel economy is common practice. Inspect components during scheduled maintenance and clean as needed rather than on a fixed schedule

Products come in aerosol spray cans for single-unit or spot cleaning and larger cans or bulk containers for frequent shop use; aerosols are convenient but typically higher cost per ounce, while bulk options lower per-unit cost. Expect category pricing to span budget under $50 to higher-priced specialty or industrial sizes, with an average in the range of about (price varies)

Many throttle-body cleaners and some carburetor cleaners can be used on EGR valves and intake passages, but avoid direct application to sensitive sensors unless the product states it is sensor-safe; follow manufacturer instructions and remove electronic sensors where recommended
