Buying advice

When choosing a carburetor or throttle body cleaner, consider the specific application: throttle body cleaners are typically sensor-safe, while carburetor cleaners are stronger but may damage sensors. For routine maintenance, a multipurpose cleaner like Sea Foam or a dedicated throttle body cleaner works well. Always follow manufacturer instructions and ensure compatibility with your vehicle's components.
