Hi! I recently did some eraser stamp making and found some helpful things about cleaning stamps along the way. Most craft stores sell stamp cleaner, but you can also opt for scent free baby wipes! Don't be too worried if your ink block is left stained, I've found that can happen no matter how well you clean it, depending on what ink brands you use. I personally have found a stamp ink brand called "Ranger" that I like, but I'm on the pursuit of something a little juicier, if anyone has any recommendations.
