PVA Towel are made from  small holes inside them help to absorb water 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.

PVA  towel  are very inexpensive. They absorb and hold water well and can last through some fairly tough cleaning jobs. PVA Towel  work well on a number of surfaces. They can even be cut into smaller sizes to provide more uses out of each sponge.  

PVA 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. PVA 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.
