Shielding Your Car's Sheen: The Ultimate Guide to Using Engine Degreaser Safely

As an engine degreaser user, many times you have to pause to ask yourself whether engine degreaser can actually strip the clear coat off your car from your glossy paintworks because you care so much about your rides. This comprehensive guide illuminates the complexities of the relationship between engine degreasers and your car paint so that your prized possession will maintain its lustre for a long time to come.

Understanding Engine Degreasers: Friend or Foe to Car Paint?

Underlying this guide is the desire to understand whether engine degreasers work well on car exteriors. It’s easy to see why products such as WD-40 are praised for their rust-proofing capability and keeping pipes and chains running smoothly. However, it only takes a little bit of ‘over-application’ for this praise to turn to doom as you may end up with an ugly stained car paint. It’s all about the components that make up engine degreasers, the materials they react with and how much of it is used.


Indeed, though some products, such as Purple Power and Simple Green, make claims to be safe for your car’s exterior, the reality is never that simple. Pay close attention to product labels claiming to be safe for exteriors of car paint. Consider any and all degreasers that advertise their safety to car paint as being potentially harmful to your car’s exterior. Assume that every safe claim your eyes touch is really not.


And even a medium-strength degreasers can strip a car clear of its protective waxy coat, which then exposes it to UV rays, temperature changes and physical elements. How important is this? The best case for a degreaser is that it strips off the wax layer and nothing else. But a stronger solution might penetrate deeper, beyond the wax and into the paint or protective clear coat, to irreparable damage. Paint protection is important.

Immediate Action: Mitigating Degreaser Damage

If you accidentally hit it when washing your car with a degreaser, you need to rinse it immediately with water to spread the degreaser and avoid it scratching your car’s paint completely; and it’s also good to go back and check the area a few days after a cleanup to see if there has been any damage that may require a bit of touch-up or another coat of wax.


Prevention, of course, is the most effective way of safeguarding the paintwork of your car. Protecting nearby painted surfaces before embarking on any degreasing process is advisable. Coat the areas around the engine and any walkways you will be passing through while tackling the dirty job.


  1. Make Good Choices: Use degreasers that are explicitly labelled as safe for applying to car exteriors.
  2. Protect and Cover: Prioritize safeguarding painted surfaces before starting your degreasing process.
  3. Use Sparingly and Diligently: Apply degreasers only to the required areas.
  4. Rinse Immediately: If contact occurs, rinse affected area with large amounts of water.
  5. Inspect and Wax: Check for damage and wax to seal the paint, once cleaned.
