Magnet Care: Make Your Car Magnets Last for Years
We would like to thank you for your support over all these years. We believe car magnets are a great way to show what you are proud of — and a quality magnet, cared for properly, will stay bright and hold firm through years of seasons. These are the same guidelines we packed with every order, expanded with everything our production room learned along the way.
Before You Apply
- Clean both surfaces. Wash the vehicle panel and the back of the magnet with a mild detergent, rinse, and dry completely. Grit trapped under a magnet is the number-one cause of paint scuffing.
- Make sure the paint is cured. Freshly painted or repaired panels need to cure fully (typically 60-90 days for repainted surfaces) before any magnet touches them.
- Choose a flat or gently curved steel surface. Magnets grip best on smooth vertical panels — doors, tailgates, trunk lids. Heavily contoured panels leave air gaps at the edges where wind can work in.
While It's On the Vehicle
- Remove the magnet often. At least every week or two — and after rain — pull the magnet off, wipe both the magnet back and the paint with a soft damp cloth, dry, and reapply. This single habit prevents nearly every problem magnets can cause.
- Rotate its position when you reapply. Paint under a magnet weathers at a slightly different rate than paint in open sun; moving the magnet a few inches each time keeps the finish even.
- Stay off horizontal surfaces in direct sun. Hoods and roofs can exceed the temperature limits of magnetic vinyl. Heat softens the magnetic material, and on a 150-degree hood a magnet can imprint into soft paint. Vertical panels run far cooler.
- Mind the car wash. Remove magnets before automatic washes — high-pressure jets and brushes will find any lifted edge. Hand washing is fine with the magnet off.
Storing Magnets Off-Season
Seasonal designs — wreaths in December, baseballs in spring — spend months in storage. Store magnets flat on a clean steel surface (a filing cabinet side is perfect) or sandwiched in wax paper inside a folder. Never fold a magnet or stack heavy objects on it; a creased magnet won't sit flush again, and a magnet that doesn't sit flush will catch the wind.
If a Magnet Loses Its Grip
Magnetic vinyl can weaken if stored hot or bent. A magnet that slides on a clean vertical panel has usually either picked up debris on its back (clean it), lost flatness (lay it on a flat steel surface for a few days), or is fighting a non-steel panel — many modern vehicles use aluminum doors and composite bumpers. Test a panel with any kitchen magnet before assuming the worst; nonprofit auto-care resources like the Car Care Council publish guidance on identifying modern body materials.
The Short Version
Clean before applying. Remove and wipe weekly. Rotate the spot. Keep it vertical, keep it cool, store it flat. Follow those six habits and the ribbon you put on the tailgate this spring will still look showroom-new when it matters — we cannot be held liable for damage caused by misuse, but in two decades the magnets cared for this way simply didn't cause any.

Quick Reference Card
Apply: clean and dry both surfaces; cured paint only; flat or gently curved vertical steel. Maintain: remove and wipe weekly and after rain; rotate the position; off before car washes. Avoid: hoods and roofs in sun, temperatures above 150°F, folding, heavy stacking. Store: flat, cool, on clean steel or in wax paper.
