Everyone, literally everyone, knows WD-40. Although this engine degreaser is convenient, same as Chemical Guys, it’s not that highly concentrated. This option is the best if you experience occasional buildup grease, have limited space in your garage (or no garage!), and need something small and handy. Also, hands-on enthusiasts who like foamy cleaning!

WHAT WE LIKE

We don’t know anything else which is easier to use than a WD-40 engine degreaser. It’s suitable for deep cleaning and has a spray-on and controlled application, so you can be very precise with its action.

WHAT WE DON’T LIKE

Forget about using it for daily usage, especially when your entire garage and all car parts are covered in grease. You will spend lots of money buying many tiny bottles once there are other options on the market with greater capacity.

PROS

  • Controlled application
  • Deep clean
  • Value for time
  • Low residue

CONS

  • Value for money

Final Verdict

In summary, choosing the best engine degreaser depends on the amount of buildup grease and the frequency it appears. As a professional mechanic, you shall look at big capacity giants and decide which one you need considering its concentration level to make your cleaning effortless. As a minimalist or someone who doesn’t use this kind of product specialized in degreasing often, we recommend choosing some handy, comfortable to use options like WD-40 or Chemical Guys degreasers.

It’s important to remember about protection during the cleaning. Most of the products aren’t harmful to skin and air passages. Still, they all might irritate and dry your body after prolonged or daily usage. Make sure you moisturize your skin after degreasing and cleaning. When some products like Chemical Guys require protective gear while using – put the gloves and mask on!
