How to Clean an Engine Bay 

Here’s what you’ll need
to get a cleaner engine:
  • Non-metallic scrub brush or pressure washer with foam cannon (if available) 
  • Garden hose

  • Clean towels or air compressor 
  • And Oil Eater® All Purpose Cleaner (if cleaning manually) or Oil Eater®  Cleaner Degreaser (if using a pressure washer) 

Washing your vehicle regularly will keep it in excellent condition and help maintain its resale value—not to mention looking great! But don’t forget to clean under your car’s hood. Keep your engine cool and extend its lifespan by periodically cleaning your engine bay. It’s easier than you’d think, with Oil Eater® All-Purpose Cleaner and Oil Eater® Cleaner Degreaser. They are powerful, easy-to-use, non-corrosive formulas that are completely biodegradable.

With the right tools and techniques, you can keep your engine looking new by removing the dirt, grime, and debris that can reduce its performance and lifespan. Learn more about the importance of engine bay cleaning, the tools required for the job, and how to do it safely.

Why Clean Your Engine Bay?

Regularly cleaning your engine bay offers several practical benefits and should be part of any car maintenance routine:

  • Locate leaks. A clean engine makes it easier to see where oil or grease originates, such as from a leaky valve cover gasket. This allows you to fix small leaks before they become major problems.
  • Protect plastic parts. Oil and grease can accelerate the wear of rubber hoses and plastic components. Using a degreaser to clean this gunk off can extend the lifespan of these parts and prevent unnecessary repairs.
  • Keep your engine cool. Layers of oil and grease can trap heat, causing your engine to run hotter. A clean engine bay can help your car run cooler, reducing the degradation of its components.
  • Improve cosmetic appeal. A clean engine is visually appealing, which is particularly important if you plan on selling your car. A bay covered in grease could jeopardize a potential sale.

Here’s What You’ll Need to Get the Job Done

To clean your engine bay effectively, it is important to gather the right tools before you begin:

Before You Start

Position the vehicle in an area that won’t be harmed by rinsed grease and grime from the engine, or cover the area under the car with a plastic drop cloth or other protective material. Start with a cool engine, and check for oil leaks before you start. Open the hood and brush out any loose dirt or leaves inside or under your windshield wipers. Protect all the electrical parts with the plastic bags and tape or twist ties. This includes the battery, alternator, distributor, and air intake system.

If You’re Cleaning Manually

Spray Oil Eater® All Purpose Cleaner over your entire engine bay. After thoroughly covering the area with cleaner, let it soak for five minutes. Scrub down the bay with a non-metallic brush to loosen the greasy buildup. Then rinse everything off thoroughly with a hose. Remove the plastic bags carefully, and then dry the engine with a towel or compressed air.

If You’re Using a Pressure Washer

Prepare your pressure washer by filling its chemical tank (if equipped) with Oil Eater® Cleaner Degreaser, being sure to dilute with water per your manufacturer’s instructions. If you don’t have dilution guidelines available, 10 parts water to 1 part cleaner is a good rule of thumb. If your pressure washer lacks a chemical tank, use a garden spray tank and a dilution ratio of 10:1 to apply the cleaner.

Apply the cleaner to the entire engine bay using a low-pressure setting or, if available, a foam cannon. Start approximately five feet away to avoid damage, and move closer as needed.

Let it soak for five minutes, and then rinse with clean water and a high-pressure nozzle. Again, start at a safe distance so you don’t force water where it doesn’t belong. Dry off your engine with a clean towel or compressed air, and you’ll be ready to roll.
