Best Carburetor Cleaner: Reviewed and Ranked

Carb cleaner blasts varnish, gum, and fuel residue out of carburetors and throttle bodies — the deposits that cause rough idle, hesitation, and hard starts on older engines. It's an aggressive solvent: great on metal, brutal on plastics, paint, and rubber, so aim carefully. On a modern fuel-injected car, a throttle body cleaner is usually the right tool instead. Reach for carb cleaner when you're rebuilding a carb, cleaning a small-engine generator, or degreasing metal parts on the bench.
