This is a sign that your stamp is well-loved. The more stains you have on the wood, and the more colors of the stains, the better!
I thought of using a Pledge (r) wipe or similar to help keep the wood conditioned. You don't want to use the wipe until after you've mounted the stamp, since you want all the gripping power you can get.
