Cleaning instructions
The encapsulated front and back covers of the books are fully sealed, edge-to-edge. The covers can be cleaned with an anti-bacterial agent or perhaps even an alcohol-based cleaner. The only area where this plasticised covering is compromised is at the holes for the spiral binding, so extra care should be taken to not allow liquid to leak into the holes.
 
The inner pages are laminated and not sealed at the ends. Any liquid that penetrates underneath the laminate will eventually discolour the pages and potentially lead to the sheets de-laminating at the edges. Anti-bacterial wipes could be used very carefully, whilst paying close attention not to get the edges too damp.
