The Double Scrubber Pad is the best tool to keep your stamps clean. One side you can use for "wet" cleaning, with either water or a stamp cleaner like UltraClean by Hero Arts (NK202).  Next, you can wipe the washed stamp on the dry side to get it dry and fully cleaned for your next stamping.  Double Scrubber Pad is 7.5" x 4.5" with a usable pad area of 7.25" x 4.25."
