How often should you clean your engine bay — and why does it matter? Here’s the pro-recommended schedule for keeping your engine looking great and protected.

Most car owners ignore the engine bay — out of fear, or because it’s not something you see every day. But the truth is, a clean engine bay isn’t just about looks — it also helps with long-term maintenance and value.

So how often should you clean it? Let’s break it down.

Why Clean Your Engine Bay?

  • Remove dirt, grease, and road grime that can cause premature wear.
  • Make it easier to spot leaks and issues early.
  • Protect plastics and rubber from drying and cracking.
  • Boost resale value — buyers love a clean engine bay.

How Often Should You Clean It?

Pro Recommendation: Every 3–6 Months

For most vehicles, cleaning your engine bay every 3 to 6 months is ideal:

  • If you drive in dusty or wet conditions, aim for every 3 months.
  • For normal daily driving, every 4–6 months works well.
  • If your car is stored or driven lightly, 1–2x per year is sufficient.

When to Clean It More Often

  • If you notice heavy dust or grime buildup.
  • After winter driving (road salt is harsh on the engine bay).
  • Before selling or showing the vehicle.
