The Double Scrubber Pad is the best tool to help keep your stamps clean. One side can be used for "wet" cleaning, with either water or a stamp cleaner like UltraClean by Hero Arts (NK202). The other side can be used for wiping dry (and further cleaning) the washed stamp. The Double Scrubber Pad measures 7.5" x 4.5" with a usable pad area of 7.25" x 4.25".
