How should I care for my car door magnets?

First, check that your car door is steel. Some vehicles have aluminum or fiberglass panels, and magnets won't stick to them. Test with a fridge magnet before you order.

• When they arrive: magnets aren't always shipped flat. Lay them flat on the hood or roof of the car in the sun for a couple of hours to flatten them.
• Before applying: the magnet and the door should both be clean and dry, free of dust and wax.
• Once or twice a week: take the magnet off, wipe both sides and the door, and let them dry. This prevents moisture and dirt from building up underneath and damaging the paint.
• Storage: keep them flat indoors, in a cool dry place. Don't stand them on their side, they can bend and then won't lie flat on the car.
• Cleaning: a soft damp cloth with water only. No abrasive cleaners.

Rounded-corner magnets have a 1" corner radius.
