Over any period, a vehicle engine will become layered with dirt, dust and grease. This is due to normal daily use. A technique used to remove these nasty elements is to steam clean your engine. Not only will this improve the life of the engine but it will lessen the risk of a fire starting in the engine. Also, anyone coming to look at your vehicle for sale will, no doubt, want to peek under the hood to see the condition of the engine. Even if they know nothing about car engines, they want to see how things look and the better they look, the better it is for you because they’ll know the car was cared for.

The job of cleaning an engine can take about one hour to complete. Really anyone can steam their engine but there are some safety measures you must be aware of.

Check the Manual

Be sure to first read your vehicle maintenance manual for any specific instructions that you must follow regarding engine cleaning. Before you take out the steam cleaner to clean, you want to gather some items together that you will need. The better you prepare for any kind of job like this, the easier it will be.

Since there is the chance that pieces of debris and dirt can fly out while steaming, you will need some clothing to protect your clothes, eyes and a pair gloves in which you can comfortably work in. If there are deposits on the battery terminals, you should also keep a bucket of water with some baking soda nearby to clean it using an old rag.

Dirty Water

You must have a place to get rid of the dirty water as it is illegal to simply dump waste water (which has been treated) inside a sewer gutter. You must determine a method to clean the engine so you can easily dispose of the dirty water and properly dispose of it. It would be a good idea to first check with your water provider to find out where it can safely be disposed of.

Degreasing Will Help

To clean up the accumulation of grime and grease in the engine, consider using a degreaser which is citrus or water based. A degreaser which originates from petroleum can be rough on vinyl and rubber pieces inside the engine. Depending on the overall condition of the engine, you should consider if you will use this type of substance. However, it also depends on the type of steam cleaning machine you are using since some are effective on their own as far as removing additional grime and grease.

Some steam cleaners are made to be used inside the home so they might not be as powerful, therefore it may need some type of engine cleansing product to be useful. However, you must read the instructions carefully on the product which you choose and ensure that you do not spill any of the cleanser on any car parts, vehicle circuits, cable junctions, fuse box or sensors in the engine.

Cover Up All Electronics

The most important thing is to cover up all electronics. Try to cover those particular parts to prevent any accidental spill and prevent them from becoming wet which can cause damage. What works great to cover these parts is aluminum foil as you can mold it to get a perfect fit and it does not ruin your view. Plastic and tape works well, too.

You should disconnect the battery – that’s important so we’re putting this note here in bold.

Again you should read your vehicle manual to be sure that you are familiar with any sensitive information.

Start Steam Cleaning

When you are ready to begin steaming, be certain that the engine is cool. If you used the vehicle, be sure to wait at least two hours for it to cool down.

Begin cleaning by using a medium sized brush to loosen dirt and debris (such as grime or dried leaves). Begin using the steamer to clean under the insulation area of the hood, than gradually working your way to the general area of the hood. Spread the engine degreaser product (citrus or water based) to melt any grease and grime off of the engine areas. In some instances in which the engine is very dirty, you wish to apply and second or third layer of this non-petroleum degreaser.

Use the equipment on the steamer to rinse and clean off the dirt and grease. When you are finished steam cleaning, start the vehicle and let it run for a few minutes to be sure it is operating correctly.

Detailing and Finishing Up

Once everything has dried up, it’s good to get out a bottle of Armor All and shine up some of the hoses and plastic parts in the engine compartment. Doing this will make things shine even more.

Touch things up so that you don’t have water spots everywhere. Make it look nice. You don’t have to go crazy and super detailed but your aim is to get the engine bay looking good and look like it was well cared for.

Professional Engine Steam Cleaning Tools

If you will be doing this process a lot or if you own a business where you will be cleaning up cars, there are tools and products that will help you do your job even more efficiently. There are even waterless steam cleaners that don’t require you to cover up electronics.

Conclusion

Even if you’re not getting your car ready to sell, it’s a good idea to get the engine compartment steam cleaned once a year or two. As you can see, you can do it yourself and this makes for a good project on a Saturday afternoon in the late spring or else in the summer. If you live in an area with harsh winters, go ahead and do it every spring for sure. If you think this is too much work, then there are places in your area that will do engine cleaning or steam cleaning. Check with car washes or else car detailers in your area.

How to Clean Your Car’s Engine

Engine Compartment Cleaning

If you’re considering selling your vehicle, it’s nice to get it detail cleaned. You can do it yourself or pay to have it done (up to you). Either way, make sure you get the engine compartment cleaned and you’ll get more money for your car. Anyone coming to look at your car and buy it will want to take a look under the hood to see what shape it’s in. If it’s clean and all the fluids are up to correct levels, then that’ll be an indication that the car was taken care of.

In this article, I’ll go over some tips and things to know about cleaning your car’s engine compartment.

Briefly… My Car

I’ve had my current car since October but haven’t had a chance to clean under the hood yet. I live in Wisconsin, so it gets cool at the end of October and that lasts through April usually. This year, we’ve had a lot of rain so there hasn’t been much of a chance to do it myself. I’ve been taking my car to the good local car wash often enough (not as often as my black Acura I had – this car is silver, which is nice because it shows less dirt… I love that) and I had it detailed once but I haven’t had a chance to do it myself yet – and I like to do it, actually.

Finally, today, I got the chance to clean under the hood. A guy there saw me taking pictures under the hood and asked if I was selling the car. I told him I was doing this for my blog. I think he was disappointed. When people see others taking care of their car, that makes them more attracted to the car. Doing this work at a local self-serve car wash may actually attract some buyers – it did for me and I wasn’t even selling it!

For me, the car really doesn’t feel like mine until I’ve had a chance to clean it really good – so I’m glad I finally got that chance today.

The Before Picture

Ok, here’s the before picture:

It’s a little dirty but not too bad at all. It’s a 2009 and I got it from the dealer back in October, so it was clean back then. It has been one winter, though and it’s due for a cleaning. Everyone should clean under the hood of their car at least once a year. I like to do it in the spring and then in the fall so that it’s clean going into winter.

Some Tips for Cleaning Your Car’s Engine

1. The Car Should be Cooled Down

First, do it when the car has had a chance to cool down. You don’t want to be digging around there when it’s been running and everything’s hot or you’ll burn your hands. Give it at least a half hour to cool down. Lift the hood to help it cool faster.

2. Consider Wearing Gloves

When a mechanic works under the hood of a car, they wear gloves. They do this to protect their hands. You’ll be doing the same thing. Working under the hood is not the same as cleaning the outside of the car where everything is smooth. In the engine compartment, there are a lot of rough edges. In fact, I remembered this tip or thought of it after getting a small cut on my hand within the first few minutes. I didn’t have gloves with me, so I made sure to wrap the towel I was using around my hand more to protect it.

3. Start with a Damp Cloth

I like to start with a damp towel or cloth – it’s usually the one I used to dry off the car after I just washed the outside. Start with the area around the hood and the underside of the hood itself. Dirt leads to rust, so get all the dirt off that you can. I then tackle the other parts that seem dirty.

4. Armor All is Your Friend

Next, use some Armor All (protectant) on a cloth. I like to either spray it on a cloth and then apply it or use the Armor All Wipes. Spraying Armor All liberally everywhere under the hood isn’t such a great idea because it’ll spray in more places than you can clean and you’ll be left with white spots in places you can’t get to. It’s not like spraying it on the inside of a door where you’ll be sure to wipe it all off. You have to be a bit more careful.

5. More to Do

I’ve never seen this before but in my car, there was a filter that was full of debris. It’s a filter, apparently, for all the rain and junk that falls from your windshield and drains down. Since it’s pretty safe to say that BMWs are over-engineered, they felt it was necessary to include a filter to catch some of this debris so that it didn’t go further into the vehicle. It was easy enough to lift out the filter and dump it out, so I did that.

Your car may have something different to catch debris. If not, check in the area where the windshield meets the engine bay and clean out all that you can. Maybe use a wet vac if you have one to really get in there.

After

Here’s the after picture after I did my work:

I’m pretty happy with the results. It needed it – especially getting the leaves and junk out of the area by the windshield.

How to Properly Degrease the Engine Compartment

OK, I’ve had a number of cars that weren’t quite as clean as my 2009 BMW. The cars were older and more dirt and grease had accumulated under the hood and it was enough where just using a cloth and some elbow grease wasn’t going to cut it. In that case, you either need to do some degreasing or steam cleaning.

Know What to Cover

Not everything under your hood is meant to get wet. You can’t just get a hose or sprayer and start spraying. You’ll most likely get water into the distributor or something and then your car won’t start.

Here are the things to cover up:

• All sensors
• Distributor
• Alternator
• Spark plugs
• Battery
• Electrical connections
• Air intake

Use plastic bags with rubber bands or tape to completely seal them up.

Warm the Engine

For this part, it actually helps to have a warm engine. This will help loosen things up. Run the car for a bit or take a short ride somewhere.

Quick Spraydown

Before applying degreaser, give the engine compartment a little spray down to get things wet. Don’t use high force or a lot of pressure. Just get things a little wet so that the degreaser can use that water.

Apply Citrus Degreaser

You can find citrus engine degreaser about anywhere – try Wal-Mart or a local auto parts store. You can get a spray bottle or even a gallon or so of it, depending on how dirty things are. You just don’t want to be in the middle of this project and then have to go get more, so make sure you get enough.

Spray the underside of the hood. Get all the areas that you can. Spray it on liberally.

Next, spray the engine area. Again, use quite a bit of it.

After spraying it, you’ll want to give it some time to work – enough where it soaks in but not so much that it dries up. During this time, you can help it work by using a brush (tire/wheel brush or something – even a scrubbie sponge) and working on whatever areas you can. If it starts to dry up, then spray more degreaser on. Do the underside of the hood and parts in the engine – everywhere you can reach.

Next, hose down all areas to remove the degreaser. Give it a very good rinse. Don’t use high pressure as you may force water into places it should not be. Let the degreaser do the work.

Let it Dry

You can let the car air cool for a while now. Take the plastic bags off. Leave the hood up. Let it dry for hours. Use a towel to clean areas that you had covered up. In the video I have below, the guy used a leaf blower to help dry out the engine compartment – that’ll probably look a little strange but it’s actually a pretty good idea.

Now you can go about using Armor All to make all the hoses and plastic parts look great. Armor All also helps keep the hoses in good shape so that they don’t dry out and crack – so yet another reason why doing this once a year is a good idea.

Using WD40

Another way to clean your engine compartment is to use WD-40. What WD-40 does is displace water and helps to prevent corrosion. It does help to get things cleaner. Spray it on, then use a brush to clean it and then wipe off the area with a microfiber towel. WD-40 works very well and professionals use it to clean under the hood.

Steam Cleaning the Engine Compartment

When I had my Acura, I found a guy that did some cheap body work and paint touch-ups. He had a buddy that did engine steam cleaning. It was $100 but I thought what the heck. WOW, did it look good when he was done. The car looked brand new. I was impressed! Here’s a picture:

The nice thing about steam cleaning an engine is that it goes deep and clean everything really well. You get a good clean that just can’t be done with a rag in your hand.

If you have the equipment and know how to do this well, I bet you could start a side business steam cleaning engines. Like I said, I thought it was worth $100. Maybe it takes an hour – that’s good money.

Here’s a guy steam cleaning an engine – he didn’t cover any parts up, so do not do it exactly like he did:

Conclusion

Yes, cleaning under the hood of the car can make a huge difference. This can help a lot if you’re planning on selling the car. Heck, someone could flip vehicles really easily by buying cars that people haven’t detailed, clean them up good and then sell them for a thousand or two more. It makes that much of a difference. So why give someone else that chance? Clean your engine compartment yourself or hire a professional to and pocket the extra money you’ll get selling your car.
