A little maintenance helps your custom magnets last longer and keeps the surface underneath in good shape.
Before you apply
- Make sure any paint, clear coat, or wax is fully cured.
- Wash the surface and the magnet with mild detergent, then dry with a soft cloth (or air-dry).
Apply it correctly
- Apply only to smooth, flat, or gently curved metal.
- Make sure the magnet sits completely flat; don’t place it over molding, decals, pin striping, protrusions, or in concave areas.
- For best hold, the magnet should be 16°C or warmer when installed.
- Don’t use magnets on horizontal metal surfaces in direct sunlight (like car hoods).
- Avoid temperatures above 71°C or below -26°C.
- Cold temperatures can make magnets more brittle, so handle with care.
- Long-term sun exposure can cause uneven fading on the surface because the covered area is shielded from UV.
Clean regularly
- Remove the magnet periodically to prevent moisture or dirt buildup.
- Clean both the magnet and the surface with mild detergent and dry completely before reapplying.
- For vehicle-mounted signs, remove and clean daily.
- After waxing or polishing, wait 2 days for wax to cure before reapplying magnets.
If you see residue
- Use gentle dish soap and hot water.
- Carefully lift residue with a plastic card.
