Nobody really likes degreasing their car engine. Or the persons who enjoy this type of grueling work are too afraid to admit it.

But, if you want your engine to last longer and perform better, it would be a good idea to give it a good clean with an engine degreaser.

Driving your car to a carwash and giving it a good rub down, unfortunately, isn’t enough. This is equivalent to cleaning your room by hiding all the dust under the rug.

Your car engine can get just as dirty as the rest of your car, if not more. The road is full of dust, mud,  soot, all a plethora of other pollutants, all sticking to the hot engine block.

If you neglect your engine, you might end up stuck in the middle of nowhere. This is why it’s essential to keep your engine sparkly clean.

What’s more, a clean engine will run better, the various intakes and moving parts won’t get clogged down, and you’ll be able to spot issues such as oil leaks as soon as they appear.

Unfortunately, the market is flooded with these products, and choosing the best engine degreaser for your needs can quickly turn into a nightmare.

Don’t worry, though. You are in the right place. In this article, we give you an in-depth look at the five best engine degreasers on the market. Not just that, but we also teach you how to pick one in our buying guide.

What Are Engine Degreasers And Why You Should Buy One?

So, before we teach you how to pick the best engine degreaser for your needs, you first need to learn what they actually are.

An engine degreaser is a cleaning product that removes oil and grease from hard surfaces. Most engine degreasers contain ingredients that react with pollutants chemically, making your job of cleaning the engine a bit easier.

These products aren’t too different from their industrial counterparts. However, engine degreaser fluids for “civilian” users are far milder. Mainly because they have to be safe to use and not cause damage when they get in direct contact with your skin.

Also, you can use these products on other things than just engines. Since they have a weaker formula than industrial-grade degreasers, you can use them to clean different surfaces such as rubber, plastic, and even paint. 

Engine degreasers primarily prevent the wear and tear of your vehicle’s engine. After all, dirty parts break down way faster than clean ones. Engine oil and grease continuously build up and can accelerate the wear and tear, which will cost you in the long run. 

These products also help you get rid of dirt and grime with ease. Why? Well, since engine degreasers work the same as soap in the way that they suspend dirt and oil particles in an emulsion, they make your job a lot easier.

No matter what type of degreaser you go for, you can rest assured that your engine will run better and last longer if you keep it clean. Not to mention how a clean engine can contribute to higher resale value.

After all, a clean engine is a happy engine.

4 Factors You Need To Consider When Buying An Engine Degreaser

Now that you know what degreasers are and why you need one, it’s time to learn what factors you need to keep in mind when looking for one.  So, here are the four factors you need to consider when browsing for the best engine degreaser for your needs!

1. Type

Engine degreasers can be roughly divided into two types, water-based and petroleum-based. Both types come with their own set of pros and cons, and there is no right choice. You should choose the type you think will be most useful to you.

To help you make a more informed decision, here’s a quick breakdown:

  • Petroleum-Based Degreasers – are usually cheaper than their water-based counterparts. This is because petroleum is a naturally stronger cleaning chemical than water, which means you don’t need a lot of it to get the job done. However, they are much more abrasive than water-based degreasers. Hence, you have to be more careful when using them because they can easily damage your paintwork.
  • Water-Based Degreasers – are generally more expensive than their petroleum-based counterparts. However, they are far less abrasive, which means you can use them on more sensitive surfaces such as plastic and rubber. They are also more environmentally friendly, so you don’t have to worry about the run-off killing your lawn.

2. Dilution And Versatility

After you’ve determined what type of degreaser you’re going to go for, it’s time to consider whether you are going to use it just on your engine or to clean other parts of your vehicle.

Some degreasers are excellent for cleaning hubcaps, exhausts, some parts of the paintwork, and even the interior. However, some of these surfaces are more sensitive than others.

For a degreaser to be efficient, it has to handle built-up dirt and grime on your engine with ease. This means it has to have a powerful formula, which means you will have to dilute it so you can use it on more sensitive surfaces.

This is why we recommend you get a more powerful degreaser that can be diluted if you’re planning on cleaning more than just your engine.

3. Cleaning Power

If you want to get rid of dirt from your engine as quickly as possible, you are going to need a pretty powerful degreaser. For the best effect, you should go for a highly-concentrated degreaser or a high-strength aerosol spray degreaser. 

Some brands clean better than others, regardless of concentration. Although you can’t numerically describe how good a degreaser is, you can always take a look at the customer reviews or purchase a sample.

If you’re a professional car detailer, we recommend you get engine-specific degreasers. They generally don’t have to be diluted, are easy to use, and cut through the dirt and grime quite quickly. Some brands will even lubricate your engine.

If you’re a standard user, a high-concentration engine degreaser will do just fine.

4. Safety

The fact that so many brands are bragging how safe their degreasers are, begs the question, are they really that safe?

The answer is yes, as long as you follow the instructions. Some petroleum-based brands will surely damage your clothes and irritate your skin. This is why you should be careful when using them and carefully follow the instructions.

If you feel uncomfortable around dangerous chemicals, then you can always go for a water-based degreaser. Yes, they are, in general, less effective than their petroleum counterpart. Still, they won’t damage your clothes or your skin if you accidentally spill it.

Final Word & Our Recommendations

Before you head out and start the grueling work that is cleaning your engine, let’s round up the results.

If you’re looking for the best engine degreaser money can buy, we recommend you go for Krud Kutter Original Concentrated Cleaner/Degreaser. Not only does this product cut through dirt, grime, and grease, but it’s also incredibly versatile.

Our runner up is the Simple Green 19128 Crystal Industrial Cleaner/Degreaser. Not only does this product’s powerful formula do an excellent job at cleaning your engine, but it’s also wholly odor-free.

If you’re looking for the most affordable option, you might want to check out the Oil Eater Original Cleaner/Degreaser. Even though it doesn’t have the most potent formula on the market, it will still get the job done, and you’ll save more than a couple of bucks.
