How to Look After Your Car & Van Magnets

Vehicle magnets are a brilliant, flexible way to advertise your business on the move, but a little care goes a long way in keeping them looking professional and protecting your vehicle’s paintwork.

Whether you’re using magnets daily or only occasionally, these simple tips will help you get the most out of them, avoid damage, and keep them looking great for longer.

Before You Apply Your Magnet

Before sticking your magnet onto your vehicle, it’s important to make sure both the magnet and the surface underneath are clean.
  • Always apply magnets to a clean, dry, flat metal surface
  • Avoid placing magnets over curves, ridges, trims, or body lines
  • Do not apply magnets to freshly resprayed panels (wait at least 6–8 weeks)
  • Make sure there’s no trapped grit, moisture, or dust underneath
Trapped dirt can scratch paint, and moisture can cause staining — so this step is key!

Daily & Regular Care Tips

If your magnet is on your vehicle often, regular care will prevent problems down the line.
  • Remove and reapply your magnet at least once a week
  • Clean both the magnet and the vehicle panel regularly
  • Dry thoroughly before reapplying
  • In hot weather, remove magnets more frequently
  • After heavy rain, always remove and dry
Heat and moisture can cause magnets to bond more tightly to paint — which is why regular removal is so important.

How to Store Your Magnet

When your magnet isn’t in use, proper storage helps it keep its shape and stick properly.
  • Store flat wherever possible
  • Keep away from heat sources
  • Avoid rolling or folding
  • Place between two clean flat surfaces if possible
A warped magnet won’t sit flush on your vehicle — and that can cause lifting or water getting underneath.

Common Mistakes to Avoid

Here are some of the most common issues we see:
  • Placing magnets over curved panels
  • Leaving magnets on permanently
  • Applying to dirty or wet surfaces
  • Removing by pulling straight off
  • Folding or creasing when storing
Avoiding these simple mistakes will dramatically extend the life of your magnet.

Frequently Asked Questions

When used correctly, vehicle magnets should not damage your paintwork. Problems usually occur when:

  • Dirt gets trapped underneath

  • Moisture is left for long periods

  • The magnet is left on for weeks or months

  • The panel has older or weakened lacquer

That’s why regular cleaning and removal is essential.

We recommend removing and cleaning your magnet at least once a week — more often in warm or wet weather.

Magnets must be applied to flat metal surfaces only. They won’t stick to plastic, fibreglass, or heavily curved panels.
