Removing Silicon from Base

I've been working on my base for the NCTA show. It's a wood base that I stained & polyurethaned. I went to put some silicon around the bottom edges last night & of course the silicon had hardened a bit in the tube. The hardened silicon blew out & put a glob on the stained/polyurethaned pared of the box. I let it dry awhile & pulled it up. There was a little line of unhardened silicone that eventually dried & stayed on the box. Looking back, I probably should have left it there to harden until today. What can I remove this with? The bird is not set in the box yet. Is sanding the only thing that will remove it?

 

Thanks, I'll give it a shot. I tried a tongue depressor last night, but some soapy water with that might help.
