Best Engine Degreaser: Our Top 4 Picks for 2018


Why Should You Use Engine Degreaser?

So, why exactly should you use a product like engine degreaser to provide a bit of spring cleaning to your vehicle’s engine? Before answering this question, lets look at what this chemical actually is.

This hard-working fluid consists of chemicals that are specifically targeted to eliminate the two toughest substances that can damage your engine – oil and grease. Although oil is necessary to keep your engine purring like a kitten, if this thick black substance is leaking all over the electrical components of your engine your vehicle is in for trouble. The same can be said for other greasy fluids like power steering or transmission fluids and even gear oil that can quickly lead to the corrosion and disruption of many other engine mechanisms.

Along with the benefits of avoiding electrical system failure and spotting fluid leaks, using an engine degreaser to clean your vehicle’s engine can also lead to more efficient engine cooling and even avoid a potential engine fire.

Varying Forms of Degreaser Available

Now that you are aware of the benefits that come from using engine degreaser, the next step is to become aware of the various forms of degreasers available.

  • Earth-Friendly: This form of degreaser is composed of environmentally-friendly products like lemon juice, baking soda, vinegar, soap and cornstarch, which are all very effective in cleaning engines.
  • Petroleum-Based: This common form of degreaser often works best for engine’s parts as it keeps them lubricated and working at optimal performance.
  • Citrus-Based: This eco-friendly orange peel-based degreaser uses powerful citrus extracts to remove dirt, grime, oil, grease and other potentially harmful materials from your engine.
  • check-square-o
    Foam-Based: Clings to dirt, dust, road grime and grease without risking damage to any other engine components that can come from excessive rubbing.
  • check-square-o
    Metal Solvent-Based: Often used to clean machinery, this type of degreaser has chemicals that are strong enough to quickly remove grease from bearings, joints and motors.

Which Degreaser is Best for Your Vehicle?

Although each of these forms of degreaser can clean your engine, deciding which form of degreaser will best serve your vehicle’s heartbeat is the best way to assure that it attends to your needs for many years to come. Before you begin the cleaning process it is important to consider:

Safety

The last thing that any car owner should ever want is to use a product that will cause damage. In order to clean the most important part of your vehicle safely it is imperative to check the ingredients. While performing this research, be sure that this degreaser does not contain toxic chemicals, is non-flammable and safe for any surface whether plastic, rubber or metal.

Multifunctional

Any great cleaner should have the ability to do more than just wipe off a surface. Instead, you should find a product that will clean the engine and many other fully-functional parts within the vehicle.

Odorless

Like many chemical-based substances, some engine degreasers generate an odor that can be irritating to the respiratory system. If other chemicals of this nature have caused any kind of breathing problems in the past, you either need to have your engine professionally cleaned or opt for water-based degreasers.

Vapor Proof

In order to assure that your engine degreaser is as effective as possible, be sure that any degreaser that you decide to use is vapor-proof. Otherwise, this chemical will do more to dry up prior to cleaning, doing little for you and your car.

No White Residue

Don’t you just hate using a cleaner that leaves streaks? This just leaves more work for you and potentially more damage to whatever you are cleaning, including your vehicle’s engine. If you are looking for a cleaner that does the job quickly and efficiently, you need to find a degreaser that guarantees no residue.


How to Degrease Your Engine

Now that you have spent the time to learn about the best engine degreaser for your vehicle, it is time to learn how to degrease your engine at home with your chosen degreaser. Like any process, there are precautions to take, which include:

Precautions

  • Be sure that your engine has had a chance to cool off. Otherwise, you run the risk of engine corrosion.
  • Cover all electrical components with something like aluminum foil or plastic grocery bags to assure that these important items are not damaged by either the degreaser or water used during the cleaning process. It is also important to cover the air intake or paper air filter as these will be of no use to your engine if they are soaked with water.
  • Ensure that you have high-pressure water available to rinse your engine, prior to using the degreaser as well as after.

After taking these precautions, it is time to get started on the cleaning and degreasing process. Start the process by using the high-pressure water to wash away any dust or debris. Next, spray the hood with your chosen degreaser, brush and wash away for a showroom shine.

The last step is the most important, as it involves cleaning the engine itself. To get this done quickly, spray the engine cover and all of the plastic pieces down with degreaser. If you have chosen to use a foaming degreaser, you can simply take a few moments to enjoy a nice cold beverage prior to spraying the engine off with pressurized water. Otherwise, get a good scrub brush and get to work prior to completing the engine wash.

Once the engine is dry, remove the protective components and hold on for about thirty minutes before running your engine.
