PROS

Advertised as general-purpose solvent-based degreasing cleaner, the solution is suitable for various automotive, commercial, industrial, household, and/or marine applications. You can use the product in a chain cleaning machine for a spotless drivetrain along with a smokers' toothbrush for the sprockets, chainrings, etc. 

CONS

The chemicals may cause skin/eye irritation. 

OUR VERDICT

CarPlan Ecl005 is the most versatile product on the list. It is probably the best engine degreaser too (the solution is certainly up there). The product's application range is practically limitless. The massive 5-litre can should last you for years to come.

OUR VERDICT

Autoglym AG 090017 is an excellent overall product. It is definitely the most practical degreaser here. The solvent-free formula is eco-friendly and more than suitable for residential use. It will be able to make scratches far less visible too.

The bottle incorporates these handy little notches that provide a comfortable but firm grip. The spray gun isn't too sensitive but not too tight either.

CONS

The volume is limited. 

OUR VERDICT

Maddox Detail 40101 is a well-balanced and well-rounded product. You don't have to mix it with anything. You won't need any additional assistance. The product is a polisher as much as it is a degreaser, leaving behind a lovely chrome-esque finish.

As long as the dirt/grease/grime/oil residue isn't too tough, you can safely mix the dissolvent with water (1:1 proportion), making sure the product lasts even longer than, frankly, necessary. The solution will let you clean and degrease engines, different machinery, wheels, tires, and various tools.

CONS

The plastic transparent canister has to be stored in low-light environments. 

OUR VERDICT

Provided you don't care too much for practicality, Gunk 6868 Ultra Engine Degreaser will likely fit your bill. The solution will not affect the paintwork. Your chain and cogs will look like new. The product is as effective as it is efficient.

CarPlan Ecl005

Limitless Application Range

CarPlan Ecl005 is probably the best engine degreaser on the list. At the very least, it is definitely the most versatile product here.

Advertised as general-purpose solvent-based degreasing cleaner, the solution is suitable for various automotive, commercial, industrial, household, and/or marine applications. The product can be applied directly to remove ingrained grease, dirt, grime, or oil. The formula works wonders with steel, metal, and aluminium surfaces.

It is an ace degreaser for bikes. You can use the solution in a chain cleaning machine for a spotless drivetrain along with a smokers' toothbrush for the sprockets, chainrings, etc.

Just keep in mind that the formula is far from eco-friendly. In fact, it is very much flammable and toxic formula, incorporating Alcohol Ethoxylate, Cyclicamine, and distilled hydrotreated light. The chemicals inside that formula can cause skin/eye irritation, so we highly recommend arming yourself with gloves and a mask.

Other than that, the product doesn't appear cheap at first. But considering that the can is packing 5 litres, it is definitely not expensive either.

In short, CarPlan Ecl005 is the most versatile product on the list. It is probably the best engine degreaser too (the solution is certainly up there). The massive 5-litre can should last you for years to come.

Autoglym AG 090017

Eco-Friendly Fluids

Autoglym AG 090017 is likely the most practical product in this lineup. The small bottle is easy to store and maintain. The spray gun is convenient and efficient. The cap is tight and secure but not too tight.

The only issue we have with the product from the practicality standpoint is that it isn't always as easy to remove as advertised. The people behind the degreaser claim that you'll have to do nothing but spray on, brush, and hose the solution off. However, from time to time, that "hose off" part will not suffice.

Apart from that, we've no major problems with the product. It is a powerful, water-based, bio-degradable engine and machine cleaner that works wonders rapidly dissolving oil, grease, and accumulated grime from engines, components, tools, and machinery.

Its application range is definitely not short. The product is able to clean anodised, non-original, and/or specially plated wheel finishes. You should have no issues with plastic or rubber components, including surrounding paintwork.

All things considered, Autoglym AG 090017 is an excellent overall product. The solvent-free formula is eco-friendly and more than suitable for residential use. It will be able to make scratches far less visible too.

Gunk 733

The Toughest Assignments

Gunk 733 is a silly name. But the product is anything but silly. The flammable, toxic formula is powerful and effective.

All engines, from motor vehicles to boats and even lawnmowers, are affected by grease, grime, oil, and dirt deposits. These relatively small but significant elements can (and usually do) build up to affect your engine's performance in the long run.

That's where Gunk 733 comes in. The product has been specifically formulated to deliver prolonged contact with grease, oil, and grime deposits, maximising the brush's cleaning effect on oil.

The solution is especially suitable for use on vertical surfaces of vehicles, industrial and agricultural machines. At the same time, it is perfect for bicycles and garden machinery too. The degreaser will have no issues picking up all kinds of dust and gunk that build up on the chain and cogs.

The product isn't perfect. Compared to every other degreaser on the list, Gunk 733 isn't that versatile. It is able to work with metal and aluminium surfaces but not necessarily with plastic and rubber. The solution's chemical smell is relatively strong too.

Nevertheless, Gunk 733 is nothing to scoff at. The product's powerful formula is able to tackle the toughest grease, grime, and gunk with effortless ease. You'll be able to remove rust and corrosion too. The 1-litre can lasts longer than you'd expect.

Maddox Detail Detail 40101

Practical Design

Maddox Detail 40101 is another product that is as effective as it is practical. The bottle incorporates these lovely little notches that provide a comfortable but firm grip. The spray gun isn't too sensitive but not too tight either.

As far as we're concerned, the bottle's only weak link is its volume. Half a litre isn't nothing but you'll probably have to purchase new bottles more often than you'd like. Other than that, there's nothing to complain about here.

The product's exclusive formula excels at dissolving the grease and dirt that is difficult to remove from the engine. It is suitable for all engine vehicles. It isn't just about engines too.

The solution is able to work with plastic, rubber, and aluminium surfaces. You'll have no issues cleaning and degreasing engines, general machinery, different tools, wheels, and tires.

Despite the product's effective formula, it doesn't damage the treated areas at all. Plus, it is water-based and bio-degradable, so you don't have to wear gloves and worry about your increased environmental footprint.

To put it a little differently, Maddox Detail 40101 is a well-balanced and well-rounded product. You don't have to mix it with anything. You won't need any additional assistance. The product is a polisher as much as it is a degreaser, leaving behind a lovely chrome-esque finish.

Gunk 6868

Clean and Degrease any Component

With Gunk 6868 Ultra Engine Degreaser, it is all in the name. The "ultra" part refers to the massive 5-litre canister as much as it does to the product's powerful formula. The solution is as effective as it is efficient.

Provided the dirt/grease/grime/oil residue isn't too tough, you can safely mix the dissolvent with water (1:1 proportion), making sure the product lasts even longer than, frankly, necessary. You don't have to dilute the solution but you can do that.

The product's application range leaves very little to be desired. You'll have no issues with plastic, rubber, and aluminium surfaces. The solution will let you clean and degrease engines, different machinery, wheels, tires, and various tools. It eats up rust for breakfast and corrosion for dinner. At the same time, the product's non-toxic, bio-degradable formula is as safe as they come.

As you would imagine, the massive 5-litre canister isn't too practical. The handle is alright, grippy and comfortable enough. But the canister's plastic transparent composition means it has to be stored in low-light environments. Otherwise, light exposure will likely ruin the solution.

In other words, provided you don't care too much for practicality, Gunk 6868 Ultra Engine Degreaser will likely fit your bill. The solution will not affect the paintwork. Your chain and cogs will look like new.

What Is an Engine Degreaser?

Quality cleaners have to be effective first and foremost. These engine cleaners fall under the same rule. Every single product on the list will be able to help you keep different engine parts nice and clean.

That being said, good cleaners aren't always this single-rounded. They don't have to be versatile. Sometimes, it is better to focus on specific applications and assignments. However, it is always nice when these products are also able to help you in other areas.

More often than not, these cleaners will allow you to remove grease, oil, and dirt from many different constructions and parts, including different machinery pieces, tools, wheels, tires, household items, various industrial and commercial objects, etc.

It is all about the formula behind the products. Make sure that it is safe enough to use in the areas where you're looking to use it. Keep in mind that the best formulas have to be non-toxic, non-corrosive, non-hazardous, and USDA-approved for non-food surfaces.

As versatile as these products are, they have their limits too. There's a good chance you'll be better off with one of these aluminum cleaners, drain cleaners, or glass cleaners if that's what you're looking to refresh.
