Car magnets are a versatile and effective way to advertise on the go. From kids' sporting events to temporary signage on commercial vehicles, these magnets offer an easy way to showcase your message. However, they require specific care and maintenance to ensure they stay in useable and long lasting condition. Below we will explore how to effectively use and maintain car magnets and to allow for the best bang for your dollar.
The Flexibility of Car Magnets
One of the biggest benefits of car magnets is their ease of use. You can quickly apply and remove them as needed. Car magnets can be customized to suit your situation. They're great for kids sports teams, a new commercial vehicle that hasn't been scheduled for decals or wrap or for parades/festivals.
However, there are important precautions to consider. You should never exceed speeds over 55 mph as the magnets can detach and fly off. A local school's wrestling team experienced this pain on a way to a meet. They forgot to remove the magnet while driving down US31 at 75mph and when they got to the meet they had only 1 magnet left. Studies show that driving over 55 mph increases the likelihood of magnets detaching by up to 50%. Additionally, speed isn’t the only consideration when using car magnets. Attaching magnets to a clean, dry surface aids their longevity, so be diligent about maintenance.

Weekly Maintenance: Cleaning is Key
Proper care requires some effort—but it pays off. At least once a week, remove your magnets and clean both the vehicle's surface and the magnet itself. Use a simple solution of soap and water to eliminate dirt and grime, which helps maintain adhesion.
Moreover, each time it rains, repeat this cleaning process. Rainwater can leave residual moisture that weakens the magnet’s grip. It may seem like a chore, but consistent upkeep can extend the lifespan of your magnets significantly.

Tackling Conditions: Before and After!
After cleaning, let both the car surface and the magnet dry completely before re-applying. Moisture can lead to peeling or, in more serious cases, damage your vehicle's paint.
When your magnets are not in use, store them flat. Keeping them in this position prevents creases or distortions that can compromise their effectiveness. Rolling or folding magnets can alter their shape, diminishing their ability to create a proper seal against the vehicle.
The Temporary Solution: Plan for Replacement
While car magnets are excellent for temporary needs, they aren’t meant to last forever. They work best for short-term applications.
Car magnets provide an effective solution for temporary signage. Their adaptability makes them useful for a variety of needs, from sports events to daily business promotions. However, ensuring they last requires a solid maintenance plan.
By sticking to speed limits, maintaining regular cleaning routines, and storing them properly, you can significantly extend the lifespan of your car magnets.
