Having a car is pretty much a necessity, especially when you need to get to work five days a week.

Now that we’ve covered some of the top engine degreasers on the market, let’s look at some tips that can help you make the right choice. 
Here are some important factors you should consider when shopping for an engine degreaser:
While engine degreasers are designed especially for automobiles, they can also be used for other purposes as well. This is why it’s important to look for a versatile option, as you might want to use one cleaner for multiple purposes. To cover all your bases, invest in a degreaser that targets different surfaces, like plastics, painted materials, and so on. 
When you buy a versatile degreaser, you won’t have to buy separate cleaners for every surface you want to clean. If you experience any spillage in the garage, you can easily clean it up using the same product you use for your engine. You should know, though, that these multi-purpose cleaners tend to be on the milder side when it comes to their effectiveness, and this is because they target various materials. Keep this potential downside in mind, but in general multi-purpose and multi-surface cleaners can efficiently help you clean both your engine and other surfaces as well. 
Engine degreasers are known for their pungent and foul odors. While this can make them unpleasant to use, this smell is proof that you have a working product — this signature smell is usually because of the cleaners’ petroleum base, and while this base has a bad smell, it’s important for breaking down stubborn grease. 
You can also find engine degreasers with added fragrances to mask their smell, but it depends whether you want to invest in a mild product with a better smell or simply work through it and endure a powerful cleaner’s foul smell with a face mask. 
Key ingredients  
Just like any other cleaning agent, an engine degreaser’s ingredients are the most important thing to consider when shopping around, and you should buy something suitable for your needs. If you buy a mild cleaner, it won’t be enough to thoroughly degrease your car. If you instead invest in an excessively harsh product, it might cause damage to your vehicle. This is why it’s important to take a close look at the key ingredients and select something that’s right for your needs. 
Most people generally prefer moderate cleaners and degreasers for home use. This is because such cleaners aren’t too harsh, but they aren’t too mild either and can get the job done efficiently. 
Take a look at these tips to pick the right engine degreaser for your ride:
There are many types of engine cleaners on the market, but the following are the two most common types that you should know about, especially if you’re looking to pick up an engine degreaser yourself:
Water-based engine degreasers are one of the most common forms of cleaning products. They usually tend to be a bit gentler and milder compared to their petroleum-based counterparts, but this doesn’t come at the cost of performance– water-based cleaners are just as effective when it comes to cleaning efficiency, and because of their mild detergents these cleaners can be used for multiple surfaces as well. 
If you have a water-based engine degreaser, you can also use it to clean your car, garage, and tools as well. When water-based cleaners come in contact with other surfaces, they don’t cause any damage, unlike harsher cleaning agents.  Although they can be a bit more expensive, water-based engine degreasers are a highly effective, eco-friendly option for cleaning your car. 
Petroleum-based engine degreasers are a wallet-friendly option that’s widely available on the engine degreaser market. Compared to other agents, these cleaners tend to be pretty harsh– due to their strong petroleum base, these products are known to strip off any grease present on engines and other car parts. 
Because of their highly abrasive nature, petroleum-based degreasers can be difficult to manage. You might need special equipment to manage them, as even a small slip-up can damage your car. What do we mean? If you’re using one and there’s accidental splashback of the cleaner on any painted surface, it will instantly damage the paint, which is why you should be careful when handling such strong agents. Despite these potential issues, their quality makes petroleum-based engine degreasers stand out, as they effectively clean your engine and get rid of any stubborn gunk and grease. If you want a heavy-duty degreaser that’s designed to intensely clean your ride, consider going for a petroleum-based degreaser. 
Engine degreasers are very important to maintain your vehicle’s engine performance. Not only that, but they also help your engine’s durability and overall can improve it significantly. We’ve given you a few of our favorite engine degreasers along with some tips about what to be on the lookout for when choosing one, and we hope we made your job a little easier when it comes to finding the right engine degreaser for you and your vehicle.
