GUNK FEB-1 Foamy Engine Cleaner and Degreaser for Cars and Trucks, Aerosol, 17 oz

I recently tried out a new car engine cleaner, and it genuinely surprised me with how effective it was and easy to use. My engine bay had the usual mix of dust, oil mist, and stubborn grime that builds up over time, and this cleaner handled all of it with almost no effort on my part. The spray went on evenly and clung well to vertical surfaces—something cheaper cleaners usually struggle with. After letting it sit for a few minutes, the grime loosened up enough that a light rinse was all it took to reveal a much cleaner engine. I didn't have to scrub aggressively, and it didn't leave behind any residue or chemical smell. One thing I appreciated was that it didn't discolor plastics, hoses, or metal components. Some degreasers are harsh, but this one felt balanced: strong enough to cut through buildup, but gentle enough to use regularly without worrying about damage. Performance-wise, the engine bay looks noticeably better, and the cleaner helped remove enough buildup that the engine seems to run a bit cooler. For the price, it's a solid value—especially compared to premium brands that don't necessarily perform any better. Overall, this is a reliable, easy-to-use engine cleaner that delivers professional-looking results without the hassle. I'd definitely buy it again.

I love gunk always have used their glass cleaner and engine degreaser but this foam is next level after letting sit on some dirty oil buildup left behind and then sprayed with medium light water pressure washed right off , i haven't used on plastic but this paired with gunk engine protect is the perfect combo for making medal in your engine bay clean and shinny to give that once showroom look
