With this cleaning set you easily wipe the ink off a single card:

1. Fill the spray bottle with water.
2. Spray once on the card so the ink comes off.
3. Wipe the card clean with the cloth.

Because of the magnet inside the cloth, you easily hang it on the board.

The cloth can be washed in a washing machine because the magnet inside is sealed.
Use the running tap for cleaning more cards at once.
