Best Engine Degreaser 2018- Reviews And Buyer’s Guide

There’s nothing better than popping open the hood of your car and seeing a perfect, pristine engine. Over the years, your car’s engine takes a beating. Sure the basic maintenance will take care of most of the mechanical issues, but what about aesthetics? Far too often engines are covered in layers of gunk and grease. And no, sadly your trusted microfiber towels won’t work here – It’s about time to clean that engine and restore it to its former glory. Engine degreaser is one of the best ways to clean off the gunk that has accumulated and these are some of the best engine degreaser brands out there.

How to Use Engine Degreaser

There is one question first. How do you use degreaser? How to clean one’s engine isn’t exactly common knowledge, but it can be very simple.

First, before you go spraying down your engine, make sure the engine has been off for awhile. Spraying cold water onto a hot engine is just asking for trouble. It’s also good to cover any exposed electrical components with a plastic bag. This will avoid any future complications with the electronics in your vehicle.

After you’ve prepped your engine for cleaning, spray it down with water. The water will knock loose dirt and other larger particles. The degreaser will have a much easier time doing its job if the engine is clear of dirt. It’s very important to use a gentle spray. Don’t use a high pressure hose as it could get water into areas where it doesn’t belong.

Now that your engine is ready for the degreaser, you can spray it all over the engine. How much you spray and how long you wait depends on the brand, but usually a good five minutes is enough time. From here you can use a scrub brush to knock off the bigger chunks of grease.

Finally, rinse it all off with water and your engine should be sparkling like the day it came out of the factory. If you are still not happy with the results, simply repeat the process until you’re satisfied.
