What dissolves silicone

[hillegom]

I was going to use a 50 gal for my sump for my new 120 gal. However the 50 gal leaked, so I took it all apart. Just have the glass panes apart now. But was trying to get all the silicone off before resiliconeing everything back together.
I remember someone here said acetone worked. Before I go and buy any, has anyone else tried this?
BTW it sure was a pita getting all the panes apart!!!
Thanks
