There are easy and efficient ways on howto remove mildew that has accumulated on your old books. The effect of mildew on books is grave, as this can damage a book entirely to a state that it can no longer be read and must be disposed of. Below are the materials that you need along with the instructions on how to remove mildew from books.
Step 1 – Place Book Under the Sun
Open the book and fan the pages. Keep it open and lay your book under the heat of the sun for about 45 minutes. After this amount of time, place the book in a much shadier area. Keep the book fanned open for another hour under the shade. After one hour, place the book under the heat of the sun for 45 minutes more. This process should eliminate the odor that the mildew emits. If the odor is still there, simply repeat this process.
Step 2 – Place Book in Freezer
Place the book inside a sealable plastic bag. Place the plastic bag inside your freezer. Keep the book there for several days. Every once in a while, take the book out of the sealable plastic bag to check on the mildew.
Step 3 – Use Scented Sheet
Use a scented dryer sheet inside the plastic bag to remove the odor of the mildew. Keep the dryer sheet inside the sealable plastic bag for about a week.

Bookshelves Tend To Accumulate Humidity
Most bookshelves that hold books have their backs flush against the wall. Usually, bookshelves are placed at the edge of the room where the sun does not shine to avoid sunburn. However, these are the conditions that molds prefer.
Mold spores are airborne and begin to actively reproduce when the humidity is above 70%. Bookshelves are often placed in the corners of a room where humidity tends to accumulate. In addition, bookshelves lined with books or double shelves have poor airflow. As a result, the humidity is higher in the back, making it easier for mold to grow.
Thin books, such as school notebooks used, are rarely stored in bookshelves for long periods of time. And this is a factor that doesnt usually get mold.
How To Prevent Mold On Books Or In Book Collections
Humidity is the number one condition for the growth of mold and mildew on books. It is the moisture in still, quiet air that allows mold spores to grow and spread so quickly on books. Lets take a look at the best ways to prevent mold on books.
Keep your books on a shelf that gets a decent air flow. Traditional bookcases and bookcase setups actually promote mold growth. First, the bookshelves are made of wood which mold loves. Second, most people crowd books onto each shelf and space the shelves close together to fit as many books as possible. Your books need space. Make sure the shelves are at least 2 inches apart and leave some wiggle room between each book.
Do not store books in a closet, basement, or against an outside wall of the house. Again this is an airflow issue as well as a moisture issue.
Dust your books as well as your bookcase once a week. Mold spores move around in dust.
Make sure that the humidity levels in your home stay low and use a dehumidifier if necessary.
Keep the air circulating in your home by using your HVAC, ceiling fans, and desktop fans.
Be sure to use an air purifier to capture any mold spores that might be tempted to make a home on your books.
Keep houseplants away from your library! Houseplant soil is notorious for mold. The moisture will also encourage mold growth on your books.
And thats it! How to remove mold from books as well as how to prevent it in the first place. Do you have any ideas to share? Please feel free to leave a comment!

Books Are Rich In Food For Molds
Molds grow by feeding on dust, hand sweat, and hand stains. Even if you clean your room frequently, it is unlikely that you clean your bookshelf as often as you clean your room. When you clean your room with a vacuum cleaner, it is a good idea to dust the books on the bookshelf as well.
As for hand sweat and hand stains, although it may be bothersome, washing your hands before reading a book will prevent mold to a great extent.
Responding To Active Mold
The actions recommended below are basic stabilization techniques that can be implemented in-house for small to moderate outbreaks. The complexities of dealing with a large number of moldy materials will usually require outside assistance from an experienced mold remediation vendor. See Working With Mold Remediation Vendors.
The amount of materials that can be dealt with in-house will depend on the extent of the damage, available staffing, and available space and equipment. Consult with a conservator or preservation professional if you have questions about the salvage process or if additional conservation treatment is necessary.
NOTE: The following steps are numbered for convenience. The process may not always unfold in exactly this order, and some of these activities will occur simultaneously.
For salvage of wet materials, see NEDCC leaflet 3.6 Emergency Salvage of Wet Books and Records.
1. Implement safety protocols for all individuals working with mold.Personal Protective Equipment should be worn to prevent adverse health effects. PPE should include:
2. Isolate the affected items, collection, or area.
3. Determine the cause of the mold growth. You need to know what is causing the problem so that additional outbreaks can be avoided.
Initiate repairs or resolve the problem as soon as possible. If the problem cannot be resolved quickly, salvage the collections and frequently monitor the area for additional mold growth.
5. Deactivate any active mold growth.

Identifying Mold And Mildew On Books
Before you start removing mold from books, its important to understand the type of fungus youre dealing with.
Mold, as described by WebMD, is a fungus that consists of small organisms that are either black, white, orange, green, or purple and can thrive anywhere as long as there are adequate nourishment and just the right level of humidity.
They especially thrive in moisture and reproduce through lightweight spores that travel through the air. Theyre quite harmless in small quantities but can be quite a hazard if left to collect en masse.
Mildew, on the other hand, shares a lot of similarities with mold and may in certain places even thrive with it, but theyre not the same type of fungus. Mildew grows on flat moist surfaces, and its damage isnt quite as extensive. Mildew on books can be removed without much trouble.
The easiest way to identify mildew is through sight and smell. As it turns out, that old book smell you love so much is mostly mildew.
Want to know how to remove mildew from books? Its not complicated and is done much in the same way youd remove mold from books.

Make A Gap Between The Bookshelf And The Wall
Since bookshelves are very heavy when filled with books, we may think attaching them right to the wall is safer. However, it is better to place them a little farther away from the wall to allow better airflow and prevent high humidity. Please ensure to avoid the bookshelf from tipping over, and leave a gap between the unit and the wall.
It is also highly recommended to open the windows as much as possible for ventilation. Finally, do not dry your washings in a room with a bookshelf. The paper absorbs the moisture and becomes a breeding ground for mold.
Eliminating The Odor Of Mildew From Books
One of the easiest ways to remove the odor of mildew from your books is by exposing them to direct sunlight.
Be careful with this method as it could warp your book cover, especially if the book was wet in the first place and if it is an old model.
If this method fails, start by airing out your book and gently separating the pages with a pair of tweezers. Then, use a hairdryer on low to medium heat to dry the pages.
Lastly, place your books in a warm and dry spot in your home.
You could also place your books in a container with a piece of material that can absorb smell and moisture, for example, a sock filled with rice.
You could also place the books in newspaper covered in a very thin layer of talcum powder.

Can Foxing On Paper Be Removed
Getting rid of the dark marks brought about by foxing is not an easy task and should be designated to a professional conservator. In most instances, the experts might select one of the two methods used in reversing the foxing process:
Warning!
- Using a reducing agent, specifically sodium borohydride. These chemicals are generally mild and dont need to be washed off the paper. However, it is likely that treatment wont fully remove the marks.
- Treating the paper with an oxidizing agent such as sodium tetraborate. The oxidizing agents are slightly stronger than the reducing agents. They must be washed out of the paper after treatment.
It is important to note that the strength of the agent used depends on the weight of the paper. With this in mind, the chemicals should be combined and applied properly by a professional. Some rare booksellers decide to leave foxing alone and simply strive to prevent further damage from occurring.
Dont forget to inspect for indications that foxing has been removed using bleach, which can cause the paper to deteriorate more rapidly over time. When bleach treatment is used, it can cause the paper to wrinkle as well as ink bleeding.
