Cover Any Sensitive Areas With Plastic Bags Or Other Waterproof Cover

Cover any sensitive areas we mentioned earlier in phase 1 with a plastic bag. Use a few rubber bands around the plastic bags to make a watertight seal and prevent the bags from getting loose or moving around. For smaller tight areas, aluminum foil is also a great option. Just take an adequate amount of aluminum foil and shape it to the sensitive area. This step will prevent excessive amounts of water from getting on or in sensitive parts.

Phase 6 Detailing: Finishing Off The Perfect Clean Engine Bay

Now that the engine bay is perfectly clean, it’s time to start detailing and adding protection to the plastic, rubber, and paint surfaces!

Starting with your plastics and rubbers, we recommend using a plastic and rubber conditioner./ This will add a nice rich, dark look to all your plastics but also condition them to prevent cracking and fading. Take your favorite plastic and rubber conditioner and apply a substantial amount on a microfiber towel or foam applicator pad, then evenly apply it throughout the engine bay.

Protect The Engine Electrical Components

Water can cause unfortunate damage to the electrical components and ultimately blow a fuse or two. However, there is a way to prevent this from happening. Simply, remove the battery from the engine and clean it separately outside. To do this, youll need to disconnect both of the battery terminals. Next, youll need to cover up all of the exposed wirings and components as well. To do this, wrap plastic around components such as the spark plug inlets and the distributor cap. Do the same for loose wires as well to make the components relatively waterproof.

Tips For Restoring Plastic

As we mentioned earlier, plastics and rubber can fade over time. If your engine bay plastics look faded, use a few layers of plastic and rubber conditioner on the affected areas, leaving a few minutes between coats. This should be able to restore your faded plastics, but if they still look faded, you might have to use a plastic dye or paint to restore the area. This can be a bit messy, but the results are worth it!

Dirty Deeds Done Dirt Cheap: How To Get A Clean Engine Bay

Polishing your vehicles posterior until it shines like glass and then leaving its engine bay untouched is like hopping in the shower and not washing your ass. Just because no one can see under there doesnt mean it isnt filthy as hell, and the longer you wait between scrubs the worse things are going to get down below.

Although hitting the car wash or scheduling a weekly car detailing routine is common practice for most people, drivers tend to forego cleaning their engine bays for a few reasons. The typical excuse you hear is that they dont want to damage any crucial components, and being that engines are typically an out of sight, out of mind part of the vehicle, it shouldnt really matter anyway. If a car engine runs fine without being hit with an engine cleaner once a year, why worry about things like stubborn dirt, carbon deposits, and grease building-up around the valve cover?

There are quite a few reasons why you should scrub where the sun doesnt shine. On older vehicles, having a filthy engine bay will only make identifying a fluid leak all the more challenging. Heavy layers of grime, road salt, engine fluids, and rust have also been known to expedite the deterioration of rubber components like vacuum lines and hoses. There is also the risk of corrosion, which can shorten the lifespan of crucial powertrain components and cause bolts to seize.

How Do You Clean A Cars Engine Bay

There are a couple of different ways to clean an engine bay. You can do it at home if you have access to a water hose and some cleaning products, at a car wash with a pressure washer, or you can have it professionally done if you dont want to do it yourself. But if you would like to clean your engine bay at home, here are the simple steps to do so:

  • Cover the battery, alternator, and distributor with plastic bags so that they dont get wet.
  • Spray the engine bay with a degreaser. You can typically find a degreaser at your local auto parts store and if you want one thats eco-friendly, then we suggest using Simple Green.
  • Scrub your engine bay using a soft-bristle brush to clean up all of the extra-dirty parts.
  • Rinse the engine bay with the water hose, while doing your best not to concentrate the hose in one place for too long. Just do an even spray throughout the engine bay.
  • Dry the engine bay using old microfiber towels.

    If the engine is running smoothly, Im hesitant to take anything apart to clean it, and Id recommend you think the same way. The old adage of if it aint broke, dont fix it has treated me well for many years. However, to get a deep clean you must dive deep. Before you start, grab your camera and snap a picture.

    “You can actually feel how clean it gets the car surface. It squeaks as you wash it and gets super smooth. I do not know what is in this stuff but it is highly effective.” – Daniel M. from Washington. 5-star review.

    Do: Use The Garden Hose

    If you need to wash off the grit and grime, resist the urge to reach for the pressure washer. Both a home pressure washer and the wand at a local DIY car wash will eject water at a dangerously high pressure and threaten just about any part of your engine compartment. The jet can easily push past gaskets, into electrical panels and connections, and also into grease fittings.

    If you discover the engine compartment is so filthy that a rinse-down is needed, take the time to seal all electrical connections and crankcase openings before using a garden hose. If the garden hose doesnt provide enough pressure, gently scrub with a soft bristle brush to break the gunk free.
