Obviously consult with a conservator before trying to remove anything form the mural.
With that said, what kind of ink do you use for the hand stamps? is it water soluble? Or, You can try rubbing alcohol, it will take off many inks. - again, make sure it wont damage the varnish before you try this.
Better yet, switch to invisible UV inks for the hand stamps, Our hands stamps are invisible unless you shine a UV light on them. Our staff members working the doors / re-entry have little UV flashlights to check the stamps.
Kids like the "Magic" of the UV light and adults don't feel awkward about inking up their hands. Lastly, there will be little motivation to mark the mural with something invisible.

Subject: Ink stamp removal
Hello!
At our museum we have a large painted mural in the lobby. Guests like taking their pictures with it, however they have been leaving marks on the mural. Can anyone recommend how to remove ink from it? We use ink stamps to mark each visitors' hand when they purchase admission. I believe the mural has been coated with several layers of varnish (?) to protect the surface. The areas are so small I don't want to incur the expense of a conservator if we can help it.
Thanks for the tips!
