When the sponge starts to show dirt, wash it with soap and water, wring it out and let it air-dry. See demonstration video at Youtube 00:11 1 sponge 3″ x 6″ x 1½” ship wt 4.8 oz $6.00

“Those cleaning sponges are GREAT for removing surface dinginess from book covers. . . .just cleaned up darkened text block edges on a book with it, too. You know, the stuff you can’t brush off? Godsey has really found the best products for the job!!”
