More elbow grease! No easy way to remove silicone. By a box of those razor blades and buy one of those little scrapers at the paint store that the razors fit in and just go to town!

I have heard that acetone works to remove silicone, but I've not used it myself. You might want to try something like goof-off, but you will have to be positive that you rinse everything out very well afterwards. Oh, and you will also want to make sure you don't get any of those items on the silicone that you want to keep on the tank.

Please do not use any type of chemical remover! The only way is with a razor. Just scrape it off.

Depending on the silicone variety, rubbing alcohol, if let sit for 30-45 minutes will remove it. This came directly from GE for their 1200 series products. I've also used a green Brillo pad type attachment on an angle grinder (really polishes the glass) I've had to move and rebuild my large tank twice now...60% of the time it works every time

the blade holder will start slipping anyway just use a razor blade, you will need several as they will dull. It takes times just be patient and keep going over it and switching to new blades

Use feeler gauge. You can get them at autozone. It has different thickness that would allow you to insert from the gaps of glass.
