Cellulose sponges are made from wood pulp, and the small holes inside them help to absorb liquid and hold it inside the sponge. These sponges are soft inside their sealed packaging because they are usually treated with a soap that keeps them pliable and keeps bacteria from growing inside the package.
Cellulose sponges are very inexpensive. They absorb and hold liquid well and can last through some fairly tough cleaning jobs. Cellulose sponges work well on a number of surfaces. They can even be cut into smaller sizes to provide more uses out of each sponge.
Cellulose sponges have a tendency to trap residue and particles, so they can be difficult to fully rinse out. These same particles can lessen the life of the sponge. Cellulose sponges should never be used to wipe up raw egg or raw meat juices. For those jobs, a more disposable paper towel is a better option.
Cellulose sponges work well on dishes, countertops, bathroom surfaces, and everyday spills.
Another version of a cellulose sponge is a flatter sponge sometimes called a cellulose wipe. These rectangular flat sponges can be used in place of paper towels, and are reusable when properly cared for. Cellulose wipes are great for dusting and polishing.
