If tiny critters and moulds have infested your books, you can kill them in the microwave. (Check for tinypinholes in the paper, which is a sign of insect infestation that could spread.)

If tiny critters and moulds have infested your books, you can kill them in the microwave. (Check for tiny pinholes in the paper, which is a sign of insect infestation that could spread.) Lay the book on the bottom of the microwave. Put an open small dish of water in with it to add some humidity to the air if the paper is extremely dry. Set on high power for 30 seconds. Stop and feel the surface of the paper ensuring that it is hot but not too hot.

Before microwaving mildewed papers, first brush off as much as you can. Then with a clean, damp cloth gently brush away the remainder on the outside surfaces and inner covers. Microwave as above, but without the dish of water.

Set out in a well-ventilated area to dry, turning the pages from time to time. Make sure the paper is thoroughly dry before storing again.
