Does cleaning your engine bay make sense?
Every car needs to have its engine bay cleaned. You can find issues that could impair the performance of your car if you frequently clean the engine. Additionally, you can stop dirt, grime, and other debris from detracting from the beauty of your engine.
How can I clean the engine bay?
When your car is clean and shiny, don’t you feel good? You might even think that a well-kept car drives better when it’s parked in your driveway or rolling down the street. But if you truly want to make your vehicle lovely, you must also take care of the muck and grime inside the engine. Dust and debris enter the engine compartment through apertures near the hood and the front of the car even though it is not directly exposed to the outdoors, at least not from above. Cleaning your engine may seem difficulthow can you clean a substantial piece of metal and plastic? but by following these ten steps, the effort may be reduced to a quick afternoon task that will be incredibly rewarding. Here’s a quick and effective way to clean your engine.
Select a warm day if possible. Warmer conditions, particularly those with little humidity and some wind, will aid in drying the engine and its components after cleaning.
Open the hood if the automobile was running and let the engine cool for at least 15 minutes. In addition to burning you, hot engine parts can be damaged by quick contraction if they are sprayed with cool water.
Take off any plastic hood coverings. These can be cleaned independently. Remove the battery’s negative terminal as well. This will lessen the likelihood that moist electrical components will result in damage. If you’d like, you can also take the battery out to clean the engine bay, although we’ve cleaned several engine bays without doing so.
Cover any delicate electrical parts, including the battery, ignition cables, and engine control unit, with plastic bags. You should also cover any exposed engine air intakes if there are any under the hood. You can omit this step if you think you’ll be extremely careful when rinsing. However, by safeguarding these electronics, you may clean more thoroughly while running a lower risk of causing any harm.
Spray degreaser liberally around the whole engine compartment. Any household degreaser, including those designed specifically for cleaning engines or kitchen appliances, will function. Simple Green was employed (we like its eco-friendly formula). Don’t hold anything back; cover every square inch.
You might not need to scrub, depending on how filthy your engine is. The valve cover, for example, may have years’ worth of caked-on grime and oil. Working the degreaser in and removing the muck will be much easier with a little brush with synthetic rather than metallic bristles. If necessary, add additional degreaser.
A normal hose will also work, however you can use your power washer on a low setting. You might also use the sprayer at the nearby self-serve carwash. Working from back to front, rinse the entire compartment to remove all degreaser. Avoid spraying water directly onto electrical components and avoid flooding regions that won’t dry quickly.
If you have access to compressed air, you can blow air into the cracks and crevices to drain more water. If not, use a shop towel or rag to wipe everything you can reach. This will help remove any lingering filth in addition to removing the water.
Remove the bags covering the electrical components and reinstall the battery’s negative terminal.
Preventing your engine compartment from becoming very unclean in the first place is the key to making this project straightforward. Your engine will look cleaner with just an hour of effort each year or two of rapid degreasing. Even though the engine in your vehicle won’t ever look as attractive as the one in the image above, having a clean engine bay will make you happy.
Is it okay to squirt water into your engine?
The dust from an automobile’s engine bay contains substances that are hazardous to the environment. Both wet and dry versions of these products shouldn’t be permitted to go into the storm sewage system. We’ll go over how to gather and manage these materials so that they can be disposed of at a hazardous waste collection location if you decide to clean your engine bay at home.
You can visit a self-serve car wash if you don’t want to clean your engine bay at home. According to the law, these facilities must recover, clean, and reuse water in a closed system that gathers and filters the dangerous materials for secure disposal. One warning: the water pressure at a self-serve car wash is much stronger than that from your garden hose, so use extreme caution if you clean your engine bay there.
Let the Engine Cool
With a cool engine, begin. Spraying water on heated objects might potentially damage them by warping and breaking, albeit it doesn’t have to be cold. Additionally, hot components could melt the plastic you’ll be using to shield electrical components or cause burns to your hands as you work. The cooling process can be sped up by lifting the hood.
This is an excellent time to assemble your equipment and materials if you are at home. You could wash and dry the car’s exterior if you’re at a self-serve car wash bay to pass the time while you wait for the engine to cool.
Now is the perfect moment to diluted the degreaser in accordance with the label’s instructions and pour it into a spray bottle, whether at home or at the vehicle wash.
Protect the Electrical Systems and Filters
If it’s possible, unplug the battery terminals and take the battery out. It should be noted that if the battery is disconnected without backup power in the majority of newer vehicles, you will lose your radio, seat positions, and other electronic information.
To safely cover the electrical components under the hood, use zip ties, plastic tape, and electrical tape. Water infiltration can harm the alternator, fuse box, distributor cap, spark plugs, and coil packs, among other components. Cover any exposed filters that might be harmed as well.
Gear Up
Use safety glasses and a dust mask to shield your eyes and mouth from flying debris due to the hazardous nature of the grime you will be removing. Your hands are shielded from stains and harsh cleaners by rubber gloves.
When working from home, place a drip tray beneath the engine and absorbent pads on the tray’s downhill side. (Obviously, not having to capture the contaminated materials if you want to operate in a self-serve vehicle wash bay.)
Dry Clean
As much dry material should be removed to begin the cleaning process. Use brushes to penetrate into nooks and dislodge buildup after vacuuming away any loose dirt. While wire brushes work best on metal surfaces, fiber brushes are ideal for synthetic and plastic surfaces. After that, use the vacuum to gather all the loose dirt. If you are at home, remove the drip tray and vacuum any debris that has accumulated inside.
Spray Down the Engine Bay
All exposed surfaces in the engine bay should be sprayed with warm water. This procedure facilitates the degreaser’s even operation and stops it from drying on the engine, which might result in spots. For this phase, using a spray bottle gives you greater control over the application and reduces the amount of water that needs to be collected. The warm water helps keep pieces from bending or splitting when they may still be hot.
Degrease
Use the spray bottle to apply degreaser to all exposed surfaces in the engine bay, paying special attention to any places where dirt has accumulated. The degreaser needs 10 minutes to work.
While you wait, empty your shop vacuum and switch it to wet operation. You can now use it to collect your tainted liquid. Use it to empty the drip tray when it fills up if you’re at home.
Rinse and Collect
Rinse off the engine compartment using a low-pressure spray. Self-serve car wash water cannons have high water pressure capabilities, so this shouldn’t be an issue at home. When using them to clean your engine bay, use caution and never pull the button to activate high pressure.
Use the shop vacuum and absorbent pads at home to manage runoff. After rinsing, use the shop vacuum to remove standing water from the engine bay’s cracks and crevices. With a cloth, thoroughly clean the entire bay, paying special attention to any areas that the degreaser missed or that require additional care. Use the spray bottle to re-rinse and wipe these areas with water.
Gather the water that has been captured after vacuuming out any extra moisture from the drop tray and the area surrounding the pads. To dispose of the used pads, seal them in plastic waste bags.

Hand Clean Electrical Parts
The electrical parts should be manually cleaned using brushes and rags while using the least amount of moisture possible. The protective plastic covering should be removed. Reinstall the batteries after these components have been thoroughly cleaned and the engine bay has dried.
Run the Car
The engine should be started and given time to reach operating temperature. Any moisture should be eliminated after this. If you have been working at home, take the bag of used pads and the basin of polluted water to a hazardous waste disposal center as a last step.
Is it okay to wash your engine bay with a hose?
Actually, this procedure is fairly easy. People sometimes overthink situations like these and make them scarier than they need to be. If you’ve already decided that it’s okay for your engine bay to be wet and you’ve done the necessary safety measures, you’ve already got an advantage. Before you start, make sure your engine is cool to the touch.
Pre-rinse
Wet it down. You are, I am aware, overcoming your worries. It’s ok. Cleaning your engine bay is made simple by using a garden hose with the nozzle set to the shower setting. You shouldn’t be concerned because this pressure is very similar to that of a light rain.
Spray any adjacent panels and the entire engine bay with water (like the front fenders). This will make it less probable for cleaner overspray to dry and leave stains on the painted surface, which is more likely to happen than not.
Break it down into sections
Create a strategy for your attack. Attempting to clean the engine bay in its entirety at once could cause your cleansers to dry on the surface. If at all possible, try to prevent that. To avoid having to redo any previously completed parts, begin at the top. In my preferred order, the front rad support area comes last, followed by the interior of the hood, the left side, the middle, then the right side.
Spray your cleaner and get to work
This could take some time depending on how complex and filthy your engine bay is. But it isn’t challenging.
Keep your wheel cleaning bucket and all of your brushes nearby as you spray on the cleaner. You’ll discover that time passes more quickly than you anticipated if you switch between various brushes to use the one that will accomplish the task at hand.
When you lift the hood, pay particular attention to the places on top of the engine because they are the most obvious. Since you probably won’t ever see it, getting all the way down the engine’s sides is not as crucial.
Final rinse
The engine bay is now clean after one more rinse to remove any cleansers. To prevent anything from drying on the surrounding panels as well, be sure to rinse them down once again.
Dry it off
This is something I like to approach in two steps. First, I clear the engine bay of 90% of the standing water using compressed air (often from a leaf blower). I start the engine and let it warm up to operating temperature after properly drying it.
The vibrations assist shake loose any stuck water, aid in the evaporation of any leftover water, and most significantly, give you peace of mind that your engine is still functioning properly.
Dress and protect it
The icing on the cake would be to dress your engine in some way. This creates a rich, polished appearance for all the black plastic and rubber. It somewhat guards against drying out as well.
The product you select will determine how you apply it. Some products perform best when applied wet and let to dry naturally, while others may perform better when applied to a dry surface and buff off after a short period of time.
Keep in mind that you want a natural finish. The sleazy “used car salesman appearance in an engine compartment is no longer popular. Instead of making it appear overly shiny, the goal is to make it appear brand new.
Can you wash a car’s engine bay?
Even though some professionals would advise against cleaning the engine bay because you could harm some of the electrical parts, you should know that newer engine bays are rather well-isolated from experiencing any water damage.
Technically, cleaning the engine bay is okay, and we advise doing so sometimes to maintain it clean, just like you would the rest of the automobile. Additionally, if you need to perform any maintenance, working within a clean engine compartment is considerably easier (and cleaner). Your mechanic might even express gratitude if anything.
Runs a clean engine more efficiently?
It is true that oily, greasy dirt can trap some heat on an engine, but it’s unlikely that this heat would be enough to overheat the engine or even just make it run hotter than usual. If a car’s engine overheats, the cooling system is more likely to blame, along with any excessive weight the vehicle is towing or hauling or other problems unrelated to the engine bay’s cleanliness. No data exists to support the idea that a clean engine performs better than one that is dirty. It’s improbable that anything as straightforward as a little cleaner or degreaser could improve the performance of a car.
A Cleaner Engine Does Offer Some Benefits
There are certain advantages to cleaning your car’s engine, though. First, by doing so, a little issue, such as a minor oil leak, can be isolated and fixed before it becomes a bigger one. An example of a leaky valve-cover gasket is where oil or grease is coming from. Additionally, using degreaser to remove the gunk may save on repairs because oil and grease can hasten the wear of rubber hoses and plastic components. And a clean engine means your hands and clothes are less likely to become soiled if you like to perform small maintenance, like checking the oil level or accessory belts.
To reach difficult-to-reach areas, several technicians and detail shops advise using a degreaser and instruments like a vacuum with a small nozzle, compressed air, or a toothbrush. Because water and moisture can harm electrical connections and parts, they are preferable to blasting an engine with a high-pressure hose or steam cleaning an engine. Even a small water spritz in the wrong spot could have disastrous consequences. Engine detailing calls for accuracy and delicacy; doing the task at the car wash or with water from your garden hose could end disastrously.
The main benefit will probably be the clean engine’s aesthetic attractiveness. Buyers now anticipate finding a clean engine when they shop because the majority of used automobiles, including many owned by private owners, are meticulously maintained before being placed up for sale. A used car’s curb appeal can suffer if its engine is unclean.
