When people wash their cars, they tend to focus on cleaning the exterior and interior, and cleaning under the hood is often overlooked. Car engines can get slimy and greasy over time and they need to be sprayed off and cleaned with the right products. With an engine degreaser, you can spray it onto your engine and it will break down the grease so it can be easily wiped off. A clean engine can make it easier to work on your car and spot leaks and damage. A clean engine bay is also nice to show potential buyers when trying to sell the car. Here are the best engine degreasers for sale at Amazon.

How to use an engine degreaser
Before using an engine degreaser, make sure you read through the instructions and most importantly, make sure your vehicle has been turned off for a while and the engine is cold. Here is our tutorial on how to properly and safely clean your engine bay.
How does a degreaser work?
According to Techspray, “A degreaser is a cleaner designed to remove grease, oils, cutting fluids, corrosion inhibitors, handling soils, fingerprints, and other contamination common in assembly, stamping and other metal fabrication in refineries, motor repair shops, airplane hangars, and factories, etc”. They also state that “the objective for a degreaser is to remove the offending soil quickly, avoiding as much wiping and scrubbing as possible”.
What can a degreaser be used on?
Degreasers can be used on engines, but are also effective on other surfaces as well. They can be used to clean tools, machinery, floors and on many other surfaces. Before using it on a surface, make sure you read the product description online or package labeling on what it can and cannot be used on.
Are degreasers and cleaners the same?
Degreasers are a subset of cleaners that are made to break down and remove grease from surfaces. All-purpose or multi-purpose cleaners are intended to cleaning all things while being able to clean grease, but not as effective at removing grease like a traditional degreaser.
