Natural Sponges

Natural sponges are actually harvested from the ocean. They are not as common to find and purchase, although home improvement and paint supply stores usually have them in stock. These super absorbent sponges are great for washing windows, and cleaning up large spills.

Because natural sponges don't trap particles and debris, they can last up to a year when properly cared for. Natural sponges are much more expensive than cellulose sponges, however.
