Mechanics and DIYers, this WD-40 Specialist carb and throttle body cleaner is seriously effective stuff! The 13.5 oz can gives you plenty of cleaning power for multiple applications, and the dual-action system really works as advertised. First, powerful solvents break down tough, baked-on carbon deposits that can cause performance issues. Then, the strong spray pressure blasts away all that grime and residue, leaving parts clean without any oily film behind. I've used this on everything from old lawn mower carburetors to modern vehicle throttle bodies, and it consistently delivers great results. Engines start easier, idle smoother, and run better at high RPMs after a good cleaning with this product. What's really nice is that it's safe for use on most unpainted metal surfaces and won't harm oxygen sensors or catalytic converters with incidental contact. The spray nozzle gives you good control for targeted application, whether you're cleaning small carburetor passages or larger throttle body surfaces. It works great on cars, trucks, motorcycles, boats, and all kinds of small engines from weed trimmers to generators. The formula evaporates quickly without leaving residue, which is important for proper engine operation. I always keep a can in my garage because it's so versatile for routine maintenance and troubleshooting performance issues. Whether you're dealing with an old vehicle that's been sitting or just doing regular maintenance on your daily driver, this cleaner makes quick work of carbon buildup and gummed-up fuel systems. Definitely a must-have for anyone who works on engines or wants to keep their equipment running smoothly!
