The engine bay is the heart of your vehicle, and keeping it clean can have a direct impact on its performance and how long it will last.

First can lower the volume and quality of the air you receive inside your car. Second, can stop the work of your car’s water drainage system and flood the interior or electronic components.

Increased Resale Value

A well-maintained engine bay can indicate how well the owner has been taking care of the car overall. Pay attention that sometimes it can be a sign that car was prepared before sale to cover some engine leaks or other problems, so even if you see a clean engine bay, it doesn’t mean you don’t need to check the vehicle in specialized service before buying it. A clean engine bay can leave a positive impression on potential buyers, enhancing the resale value of your car.

Cleaning your engine bay may sound like a complicated task, but with the right approach, you can make it by yourself effectively. Here is a step-by-step guide to help you through the process of engine bay cleaning:

Step 1: Gather Essential Tools and Supplies

Before starting your cleaning process, make sure you have all the necessary tools and supplies:

  1. Engine degreaser / All-purpose cleaner
  2. Soft-bristle brush or detailing brush
  3. Microfiber towels
  4. Water hose or pressure washer
  5. Plastic bags or covers (to protect sensitive components)
  6. Optional: dressing or protectant for plastic and rubber components

Step 2: Prep Your Engine Bay

To make the job more effective, remove any loose debris, leaves, or dirt from your engine bay using a soft-bristle brush, compressed air, vacuum cleaner, or by hand. Next, cover all sensitive components of your car, such as air intake, alternator, and electrical connections with plastic bags or covers to protect them from cleaning products and water. Also, disconnect the battery, and remove it from the engine bay to make the process safe from shorting out electric components. Make sure that all your deep sticks are in and closed to avoid water and degreaser getting inside engine oil, transmutation oil, or power steering. Double-check cups on every reservoir for engine liquids, like brakes or coolant reservoirs.

Step 3: Apply the Best Engine Degreaser

Wear nitrile gloves and safety glasses to avoid harming your skin or eyes. Make sure the engine is not hot before applying the degreaser. Spray a generous amount of the best engine degreaser all over your engine bay. Focus on greasy and dirty areas. There is no need to overspray already clean areas. Use a detailing or soft brush to agitate the degrease and break down harsh grease effectively. Following the manufactures instructions, allow the degreaser to work for several minutes to penetrate and loosen old grime and dirt.

Step 4: Rinse Your Engine Bay

Once you have cleaned your engine bay with brushes, rinse the cleaner with a water hose or pressure washes. Make sure to avoid contact with sensitive components. If you use a pressure washer, avoid using high-pressure and rinsing areas like spark plug connectors or other uncovered plugs and hose connections.

Step 5: Dry and Protect

After rinsing the cleaner, use microfiber towels to dry out the engine bay thoroughly. Also, focus on hard-reaching areas where you still may have puddled water, and soak it with a microfiber towel or vacuum cleaner. Remove plastic bags from sensitive components, and dry them out perfectly if they are wet. If desired, apply trim restorer or plastic protectors to plastic and rubber components to restore deepness of color, add a glance, and protect them from UV damage.

Making the engine bay clean is good, but keeping yourself and your car safe is crucial! For this, do not forget to follow the tips and precautions below:

  1. Wear Protective Gear: Since you are working with chemicals that are not healthy for you, use gloves, and eye protection, wear appropriate clothing, and work in a well-ventilated place. These will protect you from chemicals, debris, and water during the cleaning process.
  2. Avoid Cleaning a Hot Engine: Allow your engine to cool down before cleaning it to avoid micro-cracks or engine parts and components deformations. Using cleaning products on a hot engine can cause rapid evaporation of it.

  7. Dry Thoroughly: Water left in crevices or on sensitive components can cause corrosion or electrical issues.
