And now, some insights about how to clean your hand carved rubber stamps. They need to be careful because they are more fragile and delicate than industrial ones. Pay attention to avoid to twist or scrub them. Press the stamp several times on the work surface or on some paper to remove the excess ink. If you would like to obtain a cleaner stamp, you can also use a kneaded eraser on which to dab your stamp. You can also rinse it with some fresh water and allow it to air dry completely. But in all cases, be really careful to never scrub or scrape it, even a little hurt with your nails can damage your stamp! My recommendation is just not to want to bring the rubber to the "white" because a) it is not needed for using your correctly the stamp and b) it could damage it.
Some last words about storage stamps. It is important not to stack stamps in top of each other because they could stick to each other.

It is also preferable to avoid to expose them to excessive heat or light, this will damage your stamps.
