Leave the books affected by mould and mildew in airy place for approximately four hours. Remember to properly fan out the pages at regular intervals. From this point onwards, you need to work with each book individually.
In an oven set at 250 degree Fahrenheit, bake a cup full of calcium chloride for at least one hour. Place the heated calcium chloride and the affected book in a container and seal off the lid of the container. The book and the calcium chloride must not come in contact with each other. Leave this setup for at least two to three days before proceeding to the next step.
Use a dry clean piece of cloth to carefully wipe clean loose, dry mould. You may use a handheld vacuum cleaner to get rid of loose mould if the books are in a less delicate condition.
To get rid of heavy odours, place the book in a pail. Add a small quantity of baking soda or cedar chips to the pail. Make sure the chips of baking soda or cedar do not come in contact with the book. Seal the pail by covering it with a lid and let it stand for a few days.
Use Absorene on the spine, end and glossy pages and cover of the affected book. Accomplish this step with a light hand.
Point a fan towards the affected book and turn it on. Make sure that the pages of the book are properly fanned out. From behind the fan, spray a small quantity of household cleaner onto the book. This will get rid of mild book smells.
