My mom gave me some tiered glass cake stands a while back.
She bought them at a clearance sale and two of the stands had some nasty glue stuff on them where the top meets the pedestal. No amount of cleaning or de-gluing removed the nastiness. I tried, trust me. I ordered some glass etching vinyl for my Silhouette a while ago, and thought this would be a good time to try it out.
Ahhh....much better. You can still see the glue if you look close, but it is a vast improvement.
This is the top tier.
Bottom. This tier miraculously did not have any glue on it, so I was able to leave the middle vinyl free. I still might add a little something to this one, not sure yet.
