Old books are often the victims of dust and dust mites that can accumulate over time and cause damage. Luckily, there are several steps that can be taken to remove dust and dust mites from old books. Firstly, use a soft-bristled brush to loosen and remove any dust particles. If further cleaning is required, use a vacuum cleaner with a soft brush attachment to clean the book's cover, spine, and pages. For musty odors, place the book in a plastic bag with baking soda for a few days. Lastly, dust mites can be eliminated with a cloth moistened with mild soapy water or isopropyl alcohol. Following these steps will help keep your old books dust and dust mite-free.
