How To: Detail Your Engine Like a Professional
How To: Detail Your Engine Like a Professional
One of the most overlooked aspects of car care and detailing is our engine bay. Why? Because when you polish paint, there is no fear of damaging a $283 sensor or having water go into your intake, causing potential engine failure. Take a second and think back to the first time you started researching paint correction and the proper steps necessary to ensure success. At first, the thought of touching your precious paint with a power tool made you cringe, until you learned that, like anything else, there is a right way and a wrong way of doing things. Fast forward to present time and try to imagine going without your Flex XC3401 or Porter Cable 7424xp and picture all the swirls, water spots and scratches that you previously ignored until you discovered a machine polisher. Now if that doesn't make you cringe, nothing will.
Step outside for a minute, pop the hood on your engine bay and take a look at what you see. Unless you're one of the few that details their engine bay on a regular basis, what you're going to see is dirt, grease, and more dirt. At this point you're probably asking yourself; "How have I neglected to clean my engine all this time?!" And the answer is simple; you didn't know how. With this guide and a little help from one my favorite product lines - Detailer's Pro Series - you'll be on the fast track to an engine bay that's as clean as your BBS wheels that you meticulously detail after every wash.
Overview
This is what your typical engine looks like on a daily driver. There is literally years upon years of built up dirt and grease.
*Warning: These pictures are not for the faint of heart.*
Looks pretty nasty, right? Let's dig a little deeper and zoom in.
What to be aware of
Modern engines are complicated machines that are monitored by various computers all ran through a complex electrical system. While most of these components can safely get wet, you want to err on the side of caution and cover them up when detailing an engine.
Components to cover up on a modern car:
Now if you look at the above list and go "HUH?!" Don't worry! You don't have to be an ASE certified mechanic to safely detail an engine. You can pretty much narrow that list down to three key things:
To make it simple, an alternator is the heart of your vehicle's electrical system. On most vehicles this is a very expensive component to replace. The alternator is generally easy to locate and regardless of the vehicle, they all look the same.

The air intake, as the name implies, is how the engine breathes. Air goes through a filter and is fed into the engine. Most new vehicles have an air intake system that's not exposed. If your vehicle has an aftermarket air intake system, it will be exposed. If your air intake is exposed, simply cover it up with a grocery bag. You do not want water going into your air intake when you detail your engine.
And the last thing to look out for are electrical plugs. A modern engine is filled with dozens of electrical plugs that run various sensors. Below are two very dirty examples of what an electrical plug looks like.
Covering up the important stuff
An effective means of covering electrical plugs is with saran wrap and masking tape where needed. This will ensure no unwanted components will get wet when you detail an engine.
It's better to spend a couple extra minutes doing it the right way. It doesn't have to look pretty for photographic reasons.
To cover major electrical components when detailing an engine, aluminum foil works best. Aluminum foil is easy to work with and although it doesn't create a watertight seal, it still protects components from getting wet. When you're cleaning an engine, you'll be using a gentle stream of water, not a full blast. The components aren't getting dunked in pool so they don't have to have a watertight seal.
Alternator covered with aluminum foil. Remember, when detailing an engine, you don't want the alternator to get wet.
To play it safe, you should also wrap the dipstick with masking tape or saran wrap when detailing an engine.
Getting started
First and foremost: Never detail a hot engine. Once the necessary components are covered up, it's time to get started! Start by spraying a low-pressure stream of water all over the engine. You do not want to spray a high-pressure stream of water when detailing an engine. The goal with the initial rinse is to remove loose dirt and grease.
The Good Stuff - Doing it right the first time
If you've read any of my previous how-to articles, then you already know I'm an advocate of working smart, and not hard. When it comes time to cleaning anything with dirt, grease or grime, I like to use a product that's strong enough to clean effectively, but I also don't want to use a product that has a harsh chemical smell. The obvious cleaner of choice for this how-to article was Detailer's Engine Degreaser.
Detailer's Engine Degreaser doesn't overwhelm your senses with a harsh chemical smell, but at the same time it has the power to cut through grease and grime without a struggle. Its formula is VOC compliant and biodegradable. What sets Detailer's Engine Degreaser apart from other degreasers is the fact that its formula doesn't contain any butyl ethers or acidic detergents, which means its safe on rubber, plastic, clear coated and painted surfaces.
Simply spray Detailer's Engine Degreaser on every dirty surface in the engine bay, let it dwell for a couple minutes, and then start cleaning!
The brush of choice for the majority of the cleaning was the Mothers Wheel Brush. Don't let the name of this brush fool you because it can clean anything. It features bristles that are tightly packed together and a soft, ergonomic rubber handle. For around $7, you simply can't beat it.
To clean the nooks and crannies, I once again relied on Mothers. The Mothers Detail Brush features feathered nylon bristles attached to a soft, ergonomic rubber handle. As an added bonus, the brush features a rubber tip which works great for removing dried on wax out of seams. This brush is a must-have for engine detailing.

How To: Detail Your Engine Like a Professional
Some areas of your engine bay will require a miracle brush, and like every other aspect of car care and detailing, Autogeek has you covered. The miracle brush for engine detailing is the Daytona Speed Master Jr. With its soft, 2 inch bristles and flexible stem, the Daytona Speed Master Jr. has the ability to clean parts of an engine that no other brush could.
Part of engine detailing, or any aspect of automotive detailing in general, is the details. No small detail should be overlooked in a detail. To ensure every square inch of this engine was squeaky clean, I used Lake Country's Detail Sticks. If you find yourself looking at your engine bay, scratching your head while wondering how the heck you're going to get it spotless, pick up a set of Lake Country Detailing Sticks and wonder no more.
Once you're finished with the cleaning process, spray a low-pressure stream of water in the engine compartment. Another aspect of Detailer's Engine Degreaser that makes it so good is the fact that it rinses freely. When detailing an engine, you don't want any cleaner or residue left behind.
Drying
After a thorough rinse, you can either dry the engine with a towel, which is time consuming, or you can use what I refer to as "my little friend." That little friend is the Metro Blaster Sidekick and don't let its size fool you, this little thing packs quite a punch. The Blaster Sidekick, like other vacuums and blowers manufactured by Metro, features a quality, all-steel construction. The motor inside the Blaster Sidekick has a peak HP of 1.3 which is enough to blast out an air volume of 160mph/85CFM. Best part about the Blaster Sidekick? It's made in USA!
Dressing the engine bay
Once the engine is clean and dry, it's time to beautify and protect all the plastic, rubber and vinyl surfaces. My product of choice for dressing up an engine bay is Detailer's Trim Detailer. This is one of the newest products in the Detailer's line of car care products and it's fantastic. This aerosol-based polymer spray evenly coats all plastic, rubber and vinyl surfaces leaving a low-gloss, like-new finish. If a little over spray occurs on bare metal or painted components, it won't cause any harm. Detailer's Trim Detailer dries to the touch and it will not attract dirt or dust like oil-based dressings.
To ensure even application on components that have ribs, simply spray Detailer's Trim Detailer on a clean, dry microfiber towel and work it in to the desired surface. Remember that no small detail should be overlooked when detailing an engine.
The finished product
Check out the before and after!
And again.
Now that you have the knowledge to detail your engine like a professional, all you need is the products and a sunny Sunday afternoon. From here on out, there should no longer be any dirty engine bays on AutogeekOnline.net. :dblthumb2:

Excellent write up 
On my Toyota and Lexus vehicles the only thing I cover up is the brake fluid reservoir, nothing else and I've never had a problem. Toyota generally uses excellent waterproof connectors so it is not an issue, the alternator I don't go crazy and hit it with high volumes of water but I don't worry about it either. Remember when you drive in a heavy rain water is probably going to be driven into the various parts of the engine. Also running the engine for a few minutes after cleaning it drives out any moisture.

Great job!
You have a great post...I have added "Mothers" to my list. The other item is an electric screwdriver! However, it's over 100 degrees in the DC area this weekend so maybe I'll just visit all the parts stores. I have a really nasty smell when I first start up by then it clears out after 10 minutes. Again, great post!

Thanks fellas. 
Since I had plenty of Detailer's Engine Degreaser and Detailer's Trim Detailer left over, Jason went ahead and detailed the engine in his Toyota Tundra last Saturday.

i have done engine wash every year after winter and the things i covers are alternator, timing belt, battery terminals and O2 sensor ( the one that comes from intake manifold). have had absolute no problems.
Also the newer dressing spray are just AMAZING. I remember the 1st time i washed engine (like ages ago) i used tire spray at the end. It looked great (no doubt) and shiny BUT it was greasy and hard to remove the next time i had to engine wash.
So always use these newer dressing engine spray.
