The Best Engine Degreaser (Review & Buying Guide) in 2023 | Autance

This product really does live up to its name, and it is capable of cutting through all sorts of crud. It can cut it on a wide range of surfaces as well. This is not really a specialist product designed for the automotive world. Instead, this is a cleaner with an exceptionally wide range of applications — one of which is degreasing engines. Not only can it clean grease and oil, but it also works to clean up glue, markers and crayon, paint, and tape residue, to name a few.

It’s also a very mild product that’s water based and biodegradable, and it contains no petroleum solvents, bleach, or ammonia. You get a gallon for a great price, but some people may prefer a more specialized, dedicated degreasing product.

Is it a bird? Is it a plane? No, it’s Super Degreaser! If you’ve been on Car Autance for a while you know we question any product that comes at us with some bold claim in the product name. However, when that product also comes from a highly reputable manufacturer like Meguiar’s, then we sit up and take notice.

This product is all about the powerful degreasing action. It is a unique formula specifically designed to tackle even the toughest grease, working hard to break it down so you simply rinse it away with a good stream of clean water.

It’s also specially formulated to be residue free, so after rinsing you won’t be left with any streaks or white marks — an important feature if you really want a sparkling engine you’ll be proud to show off.

It does have a strange herbal fragrance. Some people don’t like it, some people do, and many don’t even notice it, but as a somewhat unique feature, it is worth mentioning.

This product is not a dedicated automobile cleaning product; instead, it is a powerful degreasing (and cleaning) product with a range of applications. You can spray it onto your engine and let it work its magic. It’s non-abrasive, phosphate free and biodegradable, but we suspect it may not be as gentle as some other products on this list.

For example, hidden in the instructions it warns not to use it on plastic or aluminum.  That means you need to be very careful when spraying it around your car.

It is very cheap, on the other hand. While it cleans very effectively (and very quickly) just be sure to treat this product with extra care.

After a few all-around cleaning products, we now get back to one designed specifically for use on cars, and it is made by one of our favorite brands, Chemical Guys.

This degreaser is not just orange in color for the heck of it. No, Chemical Guys harnessed the natural cleaning power of citrus to develop this powerful cleaner that is formulated to emulsify dirt, grime, and oil stains and spills. Once emulsified, the containments can be easily rinsed away with a spray of clean water.

It has a multipurpose element too and is suitable for use all over the vehicle, such as on the undercarriage and even to remove caked-on mud and grime from rims and wheels. It even works on other surfaces, so you can tackle oil stains on your garage floor and bring the sparkle back to your tools.

It’s relatively cheap, but you should note that this price buys you only 16 ounces of product – a relatively small amount since many other products on this list are sold by the gallon. It is very highly concentrated, however, so you can dilute it, whichalso adds a bit more value.

Despite its mildly aggressive name, this product from Oil Eater is actually a remarkably gentle product. It is — deep breath required here — non-toxic, non-corrosive, non-hazardous, and even USDA approved for non-food surfaces. It is also acid free and contains no abrasives or petroleum solvents.

That is an impressive list, but don’t let that detract from its main purpose. This product is made for degreasing, and it does that very well, tackling and dissolving all manner of greases and oils.

It’s also safe for use in a wide range of non-car related applications. It can be relied on to safely clean grease and oil stains from all sorts of materials, everything from carpets to asphalt. That makes this an extremely versatile product. It’s highly concentrated, so you can dilute it to suit whatever task you require, and it is a good value too. 

The crystal in the name refers to the fact that this product is crystal clear both in appearance and odor. This makes it stand out from Simple Green’s other line of cleaning products, many of which are, surprise surprise, green in color.

This means that this product lends itself very well to degreasing an engine where you really don’t want a range of containments — such as color dyes hanging around. Instead, this product is non-toxic, biodegradable, non-hazardous, non-corrosive, and non-flammable.

It is however a very effective degreaser and cleaning product, which will really get to work on your engine. It’s highly concentrated too, so you can dilute it in your spray bottle before application. That helps the product stretch a little further given the pretty high price tag.

A bottle of WD-40 Specialist Industrial-Strength Cleaner & Degreaser gives you impressive cleaning power for your car’s engine. This powerful degreasing product can tackle both grease and grime with its biodegradable, bio-solvent formula. It’s safe for use on a variety of different surfaces, and it won’t cause any corrosion, etching, or flash rust on materials like glass, aluminum, copper, and other metals. This engine degreaser is also non-flammable, non-corrosive, non-abrasive, and low in odor. Once applied, the product will powerfully and quickly break down even the toughest grease, all while keeping your car’s most important parts safe.

This engine degreaser is also quite easy to use and apply to your car’s engine. It comes with a durable, shatter-resistant trigger and easy-to-refill port. You don’t need to use a funnel, and you won’t have to worry about making a mess. You can spray this degreaser right onto your engine and let it get to work.

The good thing about choosing a multi-purpose cleaner is that you know it is going to be mild enough to use on a range of surfaces. That is somewhat understating the abilities of this cleaner and degreaser from Simple Green, which has a phenomenal list of materials it is safe to use on.

That includes painted surfaces, aluminum, polished & stainless steel, chrome, plastic, and vinyl (and much more). While you still need to be careful (as this is a powerful cleaning product), you should be able to spray it all over your engine block without having to worry too much about any product blowback coming into contact with any surface it shouldn’t.

It has a wide range of uses in the home, making it extremely cost-effective. Plus, the product is non-toxic so you don’t have to worry about the runoff getting onto your lawn when you’re rinsing the car.
