How to Choose Degreaser for Car Engine?
For those who are not car geeks, the thought of choosing an engine degreaser can be a daunting experience, especially with the large variety of brands on the market. While it seems to be confusing, you can break it all down to a few, basic common sense factors, and we’ve taken the opportunity to list a few of those factors here for you today.
By taking into consideration the toxicity, versatility, and ease of use, surface composition, as well as examining our list of the best car engine degreaser, you will be able to find just what you need with minimal hassle to you.
Non-Toxic and Eco-friendly: Make certain that you choose an engine degreaser is able to both clean and maintain your engine and is safe to use around your environment, family, and pets. When you read the content label should state ‘non-toxic’ and biodegradable, and VOC compliant. There are plenty of eco-friendly degreasers on the market from which to choose, and we have a few of them on our review.
Versatile Means Money Saving: Many top engine degreasers are also very versatile when it comes to doing other jobs around the house. As most engine degreasers come in a concentrated form, a little goes a long way, so take advantage of this. Check the label before you buy, and if you can also use that degreaser to attack everything from laundry stains to patio furniture, it is definitely a money-saving, win-win for you.
What Surfaces Can it be Used On?: This is important, as you want to make certain that your degreaser won’t damage surfaces it comes in contact with. While many degreasers are formulated to work on almost any surface and material, there are a few, such as Purple Power, that will do damage to painted surfaces or fabrics.
So, check the label before you purchase a degreaser, to ensure that the product is safe to use for not only metal but rubber, plastic parts as well. This also ensures that nothing under the hood will suffer accidental damage if the degreaser comes in contact with it.

How to Use Engine Degreaser?
Now that you have a good, basic idea about degreasers, what they do and the best brands on the market, it’s time to actually apply the degreaser to the engine and let it do its job. We have included a basic guideline to help you get started, to give you a rough idea of how the process works.
However, always remember that first and foremost, you must follow the directions on the label of your particular engine degreaser in order to achieve the optimal effect of a bright, shining and stunning grease free engine.
Gather Your Materials and Position Your Car: Read your label and see exactly what it is they state you need to get started. Generally, you will probably need your degreaser, a long handled brush, duct tape, rags to clean with, and plastic bags to toss them into.
A reservoir tray and oil absorbing granules are useful as well to catch any runoff. Remember, that it is illegal to have any degreaser enter our water supply. You never want to start the cleaning process on a hot engine, to do so will cause damage to the engine.
We recommend that you park your car in a nice sunny spot and let the engine cool. The sun will warm your engine nicely and evening while you clean. If you can, take your vehicle to a self-service car wash to clean your engine, as these establishments actually catch the runoff and can dispose of it properly.
Reservoir Tray Placement and Sealing of Electrical Parts: Even though most of today’s engine degreasers are non-toxic and biodegradable, it is still not a good idea to allow the runoff to enter our environment and risk contaminating our water supply. Take the reservoir tray and place some oil absorbing granules inside.
Next, place the tray so that it will catch the runoff. At this point, you want to start to use the plastic bags and duct tape to seal off the parts of the car you do not wish to get wet. Look under the hood for parts such as the air intake, alternator, distributor, or filters and seal them up. Remember, if these parts get wet from the cleaning, your car may not start until they dry out.
Application of the Degreaser: Follow the directions on your particular product, diluting if necessary, and begin to clean from the bottom and then work up towards the top, moving quickly because if the degreaser dries on the engine, you’ll have spots.
Leave your degreaser on for the prescribed time, and then proceed to hose off the degreaser. A hose is preferred, as there is a risk of damaging engine parts if the pressure spray is too high, so keep it gentle. Take a clean towel and dry your engine, then go and start your car and let it run for 5 minutes, as this will dry things up a bit.
Clean Up: Depending on your particular product, the cleaning process may vary, but all in all it is a quite simple procedure. Next, remove all the plastic and tape from the engine, take your reservoir, rags and anything else that may have the degreaser runoff, and dispose of it the proper way.You cannot simply toss this in the trash, so if you are unsure, contact your local auto parts establishment and they can help, and even dispose of it for you if you want.
Follow Up Care: Once you have cleaned your car’s engine to your satisfaction, it is a good idea to add engine degreasing to your vehicles maintenance plan of action. When you institute a regular plan, you’ll be surprised at how easy the and fast the process becomes. For follow up care, gather a few rags, a spray bottle of clean water, and a spray bottle of diluted engine degreaser. Take precautions to protect your cars engine components that you do not wish to get wet.
Next, take the bottle of diluted engine degreaser and lightly spray the engine, and wait the prescribed amount of time. Finish by spraying with the clean water, and wiping it clean with a towel. If you perform this engine maintenance on a regular basis, you can avoid any future issues of a filthy, heavily grease laden engine to clean.
