Compressed Cellulose Sponges
The Spruce / Leticia Almeida
Compressed cellulose sponges are sometimes called pop-up sponges. These sponges are dry and have all of the air sucked out of them prior to packaging. The sponge rehydrates when you place it in water, popping up into a normal cellulose sponge.
Compressed cellulose sponges can be attractive to some buyers because they are not usually treated with soap or biocide substances, although it’s best to check the manufacturer’s product description to make sure. However, compressed cellulose sponges can often be more expensive than other sponges.
Best for: Washing dishes and cleaning showers, windows, and floors.
