If you’ve spent time browsing car care tips online, you’ve probably seen claims that WD-40 can remove scratches from your car. It sounds almost too good to be true: a little can of multi-purpose spray from the garage shelf magically making scratches disappear. But does WD-40 really work as a car scratch remover? And is it a safe option for your paintwork?

At ChipsAway Ireland, we’re experts in professional car scratch repair, so let’s separate fact from fiction.

What Happens When You Spray WD-40 on a Scratch?

When you spray WD-40 onto a scratched panel, the liquid seeps into the grooves and temporarily hides light surface marks. It works a bit like applying a polish or wax, making scratches appear less visible because it fills in the clear coat and reflects light differently.

However, this effect is only temporary. Once the WD-40 washes off or evaporates, the scratch will be visible again.

Can WD-40 Actually Repair Car Scratches?

The short answer is no. WD-40 is not a paint or filler, so it cannot repair scratches. At best, it can mask very light scuffs for a short period of time. For deeper scratches that go through the paint or primer, WD-40 won’t make any difference at all.

In fact, using household products on your car’s paintwork can sometimes cause more harm than good. WD-40 leaves a greasy residue that can attract dirt and dust, potentially leading to more surface damage if not cleaned off properly.

The Risks of Using WD-40 on Car Scratches

While WD-40 isn’t harmful to paint in small amounts, relying on it as a scratch remover carries risks:

  • Temporary fix only – scratches will reappear once it wears off.
  • Attracts dirt – oily residue can make your car look worse over time.
  • Doesn’t address deeper damage – won’t prevent rust or further paint deterioration.

If your car has a scratch that cuts through the clear coat or paint layer, ignoring it or masking it with WD-40 could allow moisture and rust to set in, potentially causing bigger (and more expensive) problems later.

The Proper Way to Remove Car Scratches

For a long-lasting, professional result, the best option is to have scratches repaired using SMART (Small to Medium Area Repair Technology). At ChipsAway Ireland, our trained technicians use specialist colour-matching paint systems and repair methods to:

  • Seamlessly blend repairs with your car’s original paintwork.
  • Prevent rust and further damage to the affected panel.
  • Restore resale value by keeping your car looking its best.
  • Save money and time compared to full resprays.

Unlike quick DIY hacks, SMART repair ensures scratches are properly repaired and protected.

WD-40 vs Professional Scratch Repair: The Verdict

WD-40 can sometimes make minor scratches appear less visible, but the effect is only temporary. It doesn’t actually repair the damage or protect your car’s paintwork. By contrast, professional scratch repair delivers a lasting, flawless result that restores your vehicle’s finish properly. So, while WD-40 is useful for squeaky hinges or loosening bolts, when it comes to removing scratches from your car, the smarter choice is to trust the professionals.
