Types of Engine Degreaser

Of course, there are plenty of different brands of engine degreasers and a lot of ways to pick the right one. On the market, you will find two different types of engine degreasers and while picking the best one, you might get confused or even end up making the wrong choice. That is why, before telling you how to pick the best option for your needs, we will start describing the two main types of engine degreasers:

  • Foaming Engine Degreaser

Foamy cleaners are very often used by many of the auto shops that clean your engine in a professional way. Most of the times, engine degreaser have specific formulas designed to clean the grime, but they can be used for other surfaces as well.

  • Aerosol Spray Cans

But if you prefer the spray kind, you can easily find those as well. Their formulas are usually water based, less aggressive and can be used for pretty much anything, from engines to garage floors, bike chains, dirty steel, work tools, workbenches, hoods and so much more.

You can use both of them to clean your automobile engine; they both can provide good quality results and come in different sizes.

Essential Factors To Consider When Choosing The Best Engine Degreaser

First of all, it depends on what kind of surface you have to clean up. Assuming you want to clean something fragile and delicate as a motor engine, whether one from a truck or one from your personal car, you might want to consider using more than one single product if you have a lot of dirt to deal with. Diluting natural & non toxic engine degreasers with ones that are of the industrial kind will provide great results.

  • What Kind Of Clean Work Do You Have To Do?

Using foaming engine degreaser, for some, is the best solution, because they usually provide a solvent based formula that creates a reaction with the dirt. Rinsing the foam off the surface is quite easy, because you might only need to wash it off with some water.

  • What Kind Of Budget Do You Have?

Spray engine degreasers are cheaper and are less aggressive, which means that they can be used as an all-purpose cleaning product. On the other hand, they can sometimes be not as effective as the foaming ones. Their formulas are mostly water based and not solvent based, which means that they have difficult times with dissolving or removing a lot of dirt or grimes.

  • How Do You Start Cleaning Your Car Engine?

The first step is about preparing the engine for the cleaning you are going to do.

  • Check if there’s any debris caught in the engine bay.

  • Disconnect the battery.

  • Cover wiring or electronics parts.

  • Let the engine run for a few minutes, at least five.

Then you start to degrease the engine:

  • Apply the engine degreaser you bought.

  • Make sure the engine degreaser doesn’t touch any painted components.

  • Give the degreaser three to five minutes to soak the dirt you want to remove.

  • Pick a brush and start scrubbing on the grime.

  • Rinse and wash off the car’s engine with a regular water hose.

The last step is about cleaning particular engine parts:

  • For the battery terminals, use a wire brush.

  • In the battery acid, put water and baking soda.

  • Now get a bristled brush and a sponge to clean the plastic parts.

  • Use then a brake cleaner.

  • Rinse the car’s engine again with a regular water hose.
