A Guide to Dry Cleaning Products for Books
Dry cleaning is an important part of book care and conservation, providing a way to reduce surface dirt, dust, grime, and other marks without introducing moisture. Different dry-cleaning products work in different ways, and understanding their textures and characteristics can help you choose the right tool for the material and type of soiling you are addressing.
In the video below, we demonstrate several common dry-cleaning products on both softcover and hardcover books, including the Dry Cleaning Soot Sponge, Absorene Book and Paper Cleaner, Groom Stick Paper Cleaner, and Staedtler Mars Dry Cleaning Pad.
The Dry Cleaning Soot Sponge, also known as a Dirt Eraser or smoke sponge, is a soft, lightweight sponge designed to lift surface dirt and particulate matter from a variety of surfaces.
One of the most distinctive things about the Soot Sponge is its texture. It is soft and slightly springy, with a dense, velvety feel. As it is rubbed gently across a surface, the sponge gradually breaks down and releases small crumbs. These crumbs help collect and carry away dirt from the surface being cleaned.

The amount of debris produced is a normal part of using the sponge. As you work, you may notice both sponge crumbs and accumulated dirt collecting on the surface. Once an area has been cleaned, the loose debris can be removed.
The sponge itself can also be reused as long as there is clean material available. When the working edge becomes particularly grimy, simply trim away the soiled portion to expose a fresh edge.
The Soot Sponge has a mild rubber-like odor and should be used with a light touch, particularly when working with delicate or friable materials.
Absorene Book and Paper Cleaner
Absorene Book and Paper Cleaner was a soft, pliable dry-cleaning material commonly used for removing surface dirt and grime from books and paper.
Its putty-like consistency allowed it to be kneaded and manipulated during use, helping to expose fresh cleaning material as dirt accumulated.

While Absorene Book and Paper Cleaner has been discontinued, its general method of use can be replicated with another permanently soft, kneadable cleaning material: Groom Stick Paper Cleaner.
Groom Stick is a natural rubber-based, permanently soft cleaning material that is particularly useful when a more controlled, tacky cleaning action is desired.
Unlike the Soot Sponge, Groom Stick does not crumble as you work with it. Instead, it has a soft, pliable, slightly tacky structure that can be kneaded, stretched, rolled, flattened, or divided into smaller pieces.

Its natural rubber composition also gives it a distinctive smell. Groom Stick has a fairly sharp, pungent rubber odor that is noticeably stronger than the mild smell of the Soot Sponge.
The permanently soft structure makes Groom Stick especially versatile. A small piece can be used for detailed or localized cleaning, while a larger piece can be used across broader areas. It can be gently rolled, dabbed, or rubbed over the surface to pick up loose dirt and other surface contaminants.
As the exposed surface becomes dirty, the material can be kneaded to bring a cleaner portion to the outside. This allows you to continue working with the same piece while continually exposing fresh cleaning material.
The Staedtler Mars Dry Cleaning Pad is another soft and flexible option for dry cleaning books and paper materials.
One of its most noticeable characteristics is the amount of cleaning debris it produces. As the pad is worked across a surface, it releases a fine dry-cleaning material that helps loosen and collect dirt.

You will see this debris accumulate as you clean, sometimes producing a surprisingly substantial amount of residue. This is an expected part of the cleaning process rather than a sign that the pad is deteriorating unexpectedly.
After cleaning, the loose debris can be gently brushed away from the surface.
The flexibility of the pad also makes it easy to manipulate as you work across different areas of a book, although, as with any dry-cleaning method, it is important to use an appropriate amount of pressure and avoid aggressive rubbing.
Combining Dry-Cleaning Methods
These products each have different characteristics, and there is not necessarily a reason to limit cleaning to a single product.
For a particularly dirty book, several dry-cleaning methods can be used sequentially to achieve a more substantial result. A Soot Sponge can help address heavier surface grime, Groom Stick can provide more controlled cleaning and help pick up remaining contaminants, and a Dry Cleaning Pad can be used to further reduce loose dirt and particulate matter.
The products can also be selected according to the material and the type of soiling you are encountering.
Most importantly, dry cleaning should be approached gradually. Begin with a small, inconspicuous area whenever possible, use a light touch, and observe how both the material and the cleaning product respond before proceeding across a larger area.
Dry cleaning will not necessarily remove every mark or stain, nor should the goal always be to make an older book look new. Instead, careful cleaning can reduce accumulated surface dirt and grime while preserving the character and condition of the book.
Sometimes, several gentle cleaning steps can add up to a significant improvement.
