Must have for book collectors
This sponge works like a charm for cleaning old books. After acquiring a new book for my collection, if it happens to be a little dirty, or even if it doesn't look like it is, passing this dry-sponge over the surface of the cover, spine and back-cover, also inside covers, or even particularly dirty pages, leaves quite obviously dirty patches on the sponge - Dirt that used to be on the book! The books always end up looking in better condition, some remarkedly so. I just wash the sponge off in the kitchen sink and leave it to dry in the dish-rack for the next round.
