First, wet the Eraser Sponge with water, and then squeeze out the excess. 
It should be a little damp for use. Remember, this is an eraser - not a sponge. Excess water is squeezed out so that it doesn't end up on other surfaces. The water is essential to the cleaning action as it helps the Eraser Sponge "stick" to the surface. And, it does all this with just water alone!
