Benefits of Using an Engine Degreaser
This is not a product which will do 100 different things and will be good all around the household. An engine degreaser has a very specific purpose and we should stay within its boundaries. This doesn’t mean that there are no benefits. On the contrary, more and more drivers and vehicle owners nowadays turn to the best products on the market.
In the past, people would attempt to create their own best homemade engine degreaser but now we live in a time where we can safely trust proven manufacturers out there. So here’s what benefits you get from having a clean engine:
- Cleaner engine: the whole installation under the hood will simply look cleaner and will be significantly more visibly pleasing. Won’t you be embarrassed to lift the hood in front of friends or relatives so that all that dirt and build-up can be seen?
- Longer engine life: this is pretty much the main goal of every engine degreaser. It’s not just aesthetics. We also want to drive our cars longer and having a clean engine will definitely increase our chances of doing exactly that
- Smoother engine work: while this is mainly taken care of by some of the octane boosters we have also reviewed, an engine degreaser will help too. The overall sound of the motor should be smoother as the parts will be free of filth.
Engine Degreaser Buying Guide
Well, this is not a smartphone or a TV so that you have to think about a million specs. However, there might be some aspects to consider so here we will highlight them for you.
Features to Consider Before Buying an Engine Degreaser
There are 2 main types of engine degreasers available out there:
- Petrol- based: these products are mainly considered to be heavy duty engine degreasers because of their chemical composition. This means that they are effective and will rid you of many unwanted things on your engine. They are, however, pretty dangerous and you should always wear a mask and gloves when using them. Keep in mind that the excessive use of petrol-based engine degreasers might also damage the integrity of the engine.
- Water-based: here we are talking about a much gentler product. While it will get the job done, it is also easier to wash and rinse off. Some of these can also be used as kitchen degreasers although we can’t say that we recommend that.
Since we mentioned the kitchen, it is only fair if we moved to the next feature. Some degreasers can be used around your household while some are designated especially for your vehicle. Get informed on that matter before you buy anything. The ones that can clean a wider array of surfaces should be somewhat more expensive.
This is a different feature than the one mentioned above because even if a degreaser is supposed to clean only engines, it might still be (or not be) a multi-surface one. What we mean is that some products are okay when used on plastic or paint.
Others will not play well with your car paint so you might want to be careful when you do the spraying. Some people also apply the substance on their wheels and that’s fine. However, we recommend that you check out our best tire shine product reviews if you want to have flashy wheels.
- Size of the Container
We simply cannot overlook the economy aspect of engine degreasers. It is understood that you want to use the product for as long as possible and this is why investing in a larger flacon might be the way to go. On the other hand, you don’t want it lying around.
For those with brand new cars, purchasing a smaller size can be the better idea as we do not expect them to have to degrease the engine a lot.
How to Use Your Engine Degreaser
The short version of this section is to basically tell you simply: “Aim and shoot”. But there is a little bit more to that as we cannot simply make a foamy mess under our hood. There are certain steps to bear in mind:
- So the first thing to do is to look around the engine. There is no need to spray the areas where we see no build-up and filth. It is best if you first have the engine inspected for leaks as a degreaser can also battle oil residue.
Once you know where cleaning is needed, start spraying profusely. Some areas are better off left dry. For instance, the insulating mat comes to mind. This is mostly because the mat will retain the odor and you probably do not want that.
The key thing here is to not be hasty with rinsing the engine off. It is best if you let it stay like that for about 15-20 minutes. This will allow the substance to actually do its job and dissolve the dirt around the parts.
- Next Is the rinsing part. This is pretty much self-explanatory because there’s nothing to it. Don’t worry, you will not damage the engine in any way with water. At least not in those amounts.
Most engines are very well sealed and no water will get into sensitive and delicate areas. Even if it does, the moment the engine heats up, all the water will evaporate. In fact, this is how you can dry out the engine after washing it. There’s no need to wipe it off with towels. Such an ordeal is quite challenging. Simply start the engine, let it run for a few minutes and that’s it.
- If you have a can of engine protector now’s the right time to use it. It will not only make the engine look shiny but will also add a layer of protection so that you will use the degreaser less frequently.
Will Car Paint be Damaged by an Engine Degreaser?
Knowing what to do if you accidentally put engine degreaser on your car paint is vital. It is not the end of the world. But if you are quick to wash it with fresh water, you should be alright. After the paint has been dried, inspect for any damage. If needed, use a stain remover. The final step is to apply wax. For that purpose, you might want to go through our guide to getting the best car paint sealants.
