Cleaning
Wipe the surface with a soft, dry cloth. For marks, use a barely damp cloth and dry immediately. Avoid solvents, alcohol wipes and harsh detergents.
Storage
Store in a dust bag or cotton cover, away from direct sunlight and away from damp cupboards. Keep the bag lightly stuffed so it holds its shape.
Daily habits
Do not overload the bag, keep pens and keys in a pouch, and let the bag dry naturally at room temperature if it gets caught in rain.
