The White Paper sponge is the latest in the line of Akapad (Wishab) sponges. Like the familiar blue and yellow sponges, this one has incredible cleaning ability but is specifically designed for paper. As with all of this line, the blue side is simply a handle and should not be used on artifacts; this paper sponge’s cleaning surface is white. Meant for dry cleaning only, the white area will slowly crumble away as it absorbs dirt. Simply dust or sweep it away when you are finished. Sponges measure approximately 3-1/2 x 2-1/2 x 1-3/4 inches.
