Did you know a detailed engine bay increases the resale value of your car? It's a well known fact that people who take the time and effort to detail their engines also take better care of their cars. All it takes it an engine cleaner and degreaser, a detailing brush, and a little time. Engine detailing is nothing more than cleaning the exterior of the engine and the engine compartment and applying a dressing to protect and beautify the engine. It's simple to do and only requires 30-45 minutes every couple of months.
