I have some ink pads, pigment and dye based, which are considerably new... used only one or two times. The problem is that I haven't used them for a while, and now they are "dry"!! Does anyone know of any way to rehydrate them? I know that there is a product on the market that is called a stamp refresher, but, I do not wish to spend any more for this. There must be a product, or something that can be made at home that can be used to solve this problem. Any advice?
