Review on 🧼 Aero 5695 Away Tire & Engine Cleaner - 16 oz. by Jason Epstein

The product does what it promises in the instructions. If you don't need surface protection, this product is not for you. Most if not all spray degreasers will clean without damaging surrounding surfaces, so if you're only cleaning the engine bay, brake rotors, etc, it's not worth the extra cost of aero. The instructions specifically state how "friendly" the product is to the environment's surfaces. This may be important for plane owners, not car owners.
