A car engine bay is often considered unimportant or too delicate to wash and clean, but the busy engine components that make your car run do get dirty, and this can affect performance and lifespan.
Cleaning your car engine bay may even help you discover leaks before they become too serious or expensive.
Cleaning your car engine bay helps stop grease and oil from building up. When dirt and grime cake up around sensitive or duplicate parts, they can prevent you from catching problems and may eventually interfere with performance. You are more likely to sell your vehicle if you have a clean engine.
