Additionally, there is a higher chance of accidents related to mechanical parts while not having an engine degreaser usually. Just imagine, there can be some leaky gasket or oil leak that is slowly happening, but cleaning your car engine can help you realize the situation and stop it before it becomes bigger.

Thirdly, while repairing the mechanical parts is important, ensuring your car is always in a new and better status is also necessary. Who could feel great when traveling in an old, dusty, dirty car, right? Using the degreaser usually can polish the surface, remove all stain or soil, and return you a more impressive, cool, and beautiful. Now, you can have a more enjoyable ride!

9. Purple Power 4320P – Great for Cleaning Stained Gutters

Purple Power 4320P

This product truly lives up to its name – Purple Power 4320P. It is strong enough to clean even the most stubborn stains on your car exterior or carpet, thanks to its specially-concentrated formula.

The advertisement stated that you could use this degreaser on various surfaces, but we doubt that. There might be chemical reactions when you apply the liquid on certain areas, causing them to be fairly etched. Plastic and aluminum are the two materials that require you to be gentle if you do not want to end up with a rough finish. Yet, the fact that this product only costs you under $15 makes it many cleaning enthusiasts’ firm favorite.

We love how the ingredient is non-abrasive, non-flammable, phosphate-free, and biodegradable; just remember to pay extra care to the surfaces we’ve mentioned. We assure you that you will be beyond satisfied with the quality Purple Power 4320P offers.

The only downside to this product is how it works differently on several applications. For example, it might work well on cast-iron surfaces, but not as great as aluminum ones due to the substance constituting it.


  • Effortless to clean the surface
  • Works exceptionally even with the most stubborn stains
  • Budget-friendly
  • Biodegradable
  • Does a decent job on removing odors

  • Does not give equal effectiveness on different applications

Aero Cosmetic

Last, but by no means the least, let’s close our list of best engine degreaser with an easy-on-the-eye product – Aero Cosmetic! Like the motto on its labels goes “Wash all -Multi-Purpose”, this little item can give you a spotless finish on every surface you can think of. And your engine is not an exception.

But the part we find most compelling about this product is that it is not made for just four-wheel vehicles alone. Yes, we are talking about a brilliant degreaser that can wipe out the stubborn smudges and blotches on a wide range of, if not all, mechanical engines (such as boats and aircraft)

Awesome enough? Well, the best is yet to come! Aero Cosmetic’s formula manages to meet the cleaning specification of Boeing Aircraft, Airbus Industries, and McDonnell Douglass CDS. All things considered, it is something you can totally trust when it comes to beating the filth away from your dear engine.

Not to mention, the product is water-based, so you can dissolve it with water, or clean your stuff with the liquid straight from the can. Whatever will suffice!

As legit as the product might turn out, it is not without flaws. This engine degreaser performs quite poorly on black streaks. And its price makes it a hard-to-get product for some.


  • Easy to use
  • Work on multiple surface
  • Good choice for household use
  • Safe on several materials

  • Have little effect on black streaks
  • Expensive

  • You must bear in mind when to use a degreaser. In some cases, a detergent will be more appropriate for your job.
  • Never mix degreasers with other cleaning solutions.

  • When you use an engine degreaser, wearing protective clothes is considered as a must. It will help you to avoid contact with some chemicals. Wearing gloves is compulsory here.
  • Select the high-quality and eco-friendly products. When you are at the supermarket, check if your product is green-certified. Greenguard certification emphasizes protecting indoor air quality.

RTU products ensure that the water from the plant is optimally matched to the degreaser for ultimate performance.
  • In winter months, a bleu pad can be much more effective than the red pad with automatic scrubbers for cleaning floors.

Handy Engine Cleaning Tips

A degreaser is a tool used for the removal of grate and oil from rough surfaces.

The main aim of a degreaser is to remove the offending soil quickly, avoiding wiping and scrubbing. It is also a forceful spray which creates agitation and to penetrate crevices of the part.

Can degreaser do any harm to your skin?

It cannot be denied that engine degreaser has antiseptic, so it is also likely to do harm to your skin. Some eventually trigger allergy.
