What do I do to fix this? [View all]

After our mother died, Dad had run of the house and this is the result.

I just removed a blue Steuben glass box from the dining room table. There is a notable residue of blue on the wood. I can't get it off.

I tried the discreet fingernail scraping. Didn't work.
I tried the damp warm water on a soft cloth. Nothing.

I was warned not to use polish as this would integrate the blue into the wood. Frankly, I think we're there already.

I don't want an otherwise good dining room table to be ruined.

H E L P ! ! !

Thanks as always.
