If mold remains after freezing it can be exposed to one to two hours of sunlight to dry it out or set it. Mold does not die easily and may reappear. Support single sheets with dry paper towel or something stronger. Remove caked-on mud and dirt from wet items by gently dipping the papers in a bath of clear water. Wear rubber gloves to avoid contamination to yourself and damage to paper.
Dirt is easier to remove after paper has dried.
Place wet items on paper towels or unprinted newsprint paper. Spread loose materials in single layers. For a book, place regular paper towels inside the covers and then intermittently throughout the book. Open books and stand them on edge. Replace the inserted paper as it becomes soaked and invert the book.
