What Is an Engine Degreaser and How Does It Work?
An engine degreaser does exactly what it sounds like; it degreases your engine. Cars get dirty inside and out just by being driven. We clean out exteriors and interiors pretty regularly, but we rarely give any thought to cleaning under the hood. However, this is often the part of the car that gets the dirtiest. An engine degreaser cuts through grease, grime, and other junk that can accelerate the wear and tear of some important parts.
How an engine degreaser works depends on what type of engine degreaser you’re using. Some engine degreasers are water-based and need to be diluted before use. Some are ammonia-based like some household cleaners while others are petroleum-based which are particularly good for dissolving grease. Foam-based degreasers are also popular since you can just spray them under your engine bay and hose it down. What they all have in common is that they dissolve the grease on your engine left behind from gas, oil, and other essential lubricants that can leave a mess behind.
Benefits of Using Engine Degreaser
Using an engine degreaser under the hood of your car brings several benefits. One big one is that is just makes it look nicer and cleaner under your hood. The engine bay is generally the area of your car that is cleaned the least which means it can get ugly. Using an engine degreaser to thoroughly clean your engine and the parts of your car surrounding it can make your whole car feel cleaner and newer when you pop the hood and don’t see ugly grease everywhere.
On some important components of your engine, excessive grease can lead to faster wear. If you use an engine degreaser regularly, it can make part of your engine last longer. This can help you avoid mechanical problems and save money in the long run.
One benefit of using an engine degreaser that most people don’t think about is the pleasant smell that many of them leave behind. Some of the more industrial engine degreasers don’t smell good, but most of the engine degreasers you can pick up at your local auto parts store leave behind a pleasant fragrance that can make the inside of your car smell nicer.
Most Important Engine Degreaser Features and Specs
Let’s get a little more into the different types of engine degreasers we mentioned earlier.
- Water-based degreasers. They can often clean much more than just engines. Some of the most popular ones can also clean paint, plastic, and even car interior materials like carpet, leather, and vinyl. These are great to have in your garage for cleaning a wide variety of different surfaces and materials, including your engine. Many of them are also biodegradable.
- Ammonia-based cleaners. Some ammonia-based cleaners are good for use as degreasers in a car interior but aren’t quite as strong on engine bays as some alternatives. Ammonia is a key ingredient in some household cleaners like window cleaners, which makes ammonia-based degreasers great for cleaning your car windows and chrome and while it can also be used under the hood, it’s not the strongest product for this use.
- Foaming sprays. They are popular options for cutting through grease on an engine. The foam sticks to the surface that it’s sprayed onto and penetrates baked-on grime. You let the foam sit for as long as the manufacturer recommends (usually around 10-15 minutes) and spray it down with water. Foam engine degreasers usually aren’t used for any other purpose.
- Petroleum-based. These engine degreasers are effective and popular for industrial and commercial use, but they’re not very versatile. They do a great job eating through grease but can have a hard time cleaning dirt off of engines. You generally can’t use them for anything other than degreasing an engine.
Choosing the Best Engine Degreaser
The most important thing to consider when using an engine degreaser is safety. Some products are gentler on exposed skin than others and it’s very important to closely follow the safety precautions outlined by the manufacturer on the label. Read it carefully before using the product. Some might recommend wearing gloves when using it and since you’re spraying it and it gets into the air, you may even want to consider using eye protection depending on the product.
Some engine degreasers don’t play well with other surfaces including the paint on your car or your tires. If this is the case with the product you’re using, make sure you cover up surfaces that could potentially be harmed as much as you can. If you do get some engine degreaser on the exterior paint of your car, you should wipe it off as soon as you can to prevent fading or streaking.
You should also consider what exactly you’re looking for in an engine degreaser. Are you looking for one product that can clean many different surfaces? Do you have some particularly tough grease on your engine that requires a serious degreaser? Are you looking for the best product or the best value? Answering these questions can help you narrow down the perfect engine degreaser for you and your car.
It is not recommended to wash an engine while it’s hot. If you wash a hot engine with cold water, you run the risk of damaging parts. Cold water on a hot engine block or manifold can result in it cracking which could ruin your whole engine. Before you wash your engine, the metal parts of the engine should be cool to the touch. It’s okay if the engine is a little warm when you wash it, but going from extreme hot to extreme cold can cause major problems.
While a pressure washer would work just fine on the tough metal parts of your engine, there is a lot going on under your hood than just the engine itself. There are wires, hoses, clips, and other important parts that aren’t as strong and can be damaged by a pressure washer. Water is safe to use under your hood, but a pressure washer is too powerful. A simple garden hose works just fine for rinsing off an engine bay that has just been cleaned.
It’s wise to make every effort you can to cover up exposed wires before cleaning your engine. It might not seem like a big deal, but getting a chemical cleaner or too much water into a cracked or frayed wire can cause it to short circuit and potentially result in expensive repairs. It’s also a good idea to cover up any opening in the intake system. If your engine has a carburetor, try not to let the engine degreaser or too much water get inside.
Check the label on the specific product you’re using. If it says that it’s not safe for tires, then cover up your tires. If it says to avoid getting it on your exterior paint, then do what you can to cover the areas of the car that could be exposed to the degreaser. If you’re nervous about harming other parts of your car, then it’s a safe choice to go with one of the water-based degreasers that are safe to use on pretty much any surface, but you’ll still want to read the directions on the label.
Yes, water is perfectly safe to spray on your engine. Engines are designed to handle rain and puddles which means spraying it with a hose is safe. However, using a pressure washer would be overkill and could damage some of the more fragile parts in your engine bay.
It’s a good idea to let your engine dry thoroughly before driving your car again. Leave your car outside (preferably not while it’s raining) with the hood open so it can dry out.
The more often you clean your engine, the more often you’ll get the benefits from it like longer-lasting parts, a nicer-looking engine bay, and sometimes a pleasant smell. It’s good to clean your engine once or twice a year. If you have a hard time remembering when the last time you cleaned your engine was, consider doing it every time you change your oil. If you live in a harsh environment with lots of snow, dirt, sand, or other debris that can get under your hood, then you’ll want to clean your engine more frequently.
