Keep a small dish sitting close by with a rag soaked in Coke, keep it almost floating in Coke. When you are not using a stamp sit it on the rag. When you are ready to use it again, stamp it a couple times on the rag, then a few times on a clean very wet, almost floating in plain water, rag to remove the Coke and it will be like a new stamp. The Coke will eat old ink out of stamps such as deposit stamps that have been sitting around for years. It is wonderful for removing ink on stamps.

This page contains the following solutions.
I keep a few baby wipes handy (in a zip bag) to use when stamping to clean the surfaces before going on to a new color. The sooner you clean the stamp surface the better.
I use a shallow glass pie dish. Set a sponge of any type in the center. Do not use the scratchy side of any sponge, only the soft side.
