Glue from Car Dealer on inside of Windscreen

[mantaray56]

Hi, This is my first post, so be kind. We recently purchased a SV6 demo from a Dealer and they had one of those Holden Certified stickers on the inside of the windscreen. It has left a bit of an outline ( hardened glue) behind. We only really noticed it when the light was right. Now we could go back and whinge, but I think I would rather take care of it myself. We have tried Euco Oil ,Windex, soapy water, Isopopyl Alcohol, and Orange power, it has faded but it remains. Tempted to try scraping with a blade but I know it will scratch.
Any ideas, perhaps WD 40 or acetone?
I know that will eventually go with the sun, but I am anal and would like it gone, all help appreciated.
Great site by the way

Acetone can work, be careful

Wax and grease remover, turps also.

Soapy water after it is removed or windex to clean up any residue

Brake cleaner cleaned tree sap off my work van windscreen.

Brand new stainless razor blade (won't scratch) and a quick scrape will sort it.

Wax a grease remover only. Then a windex afterwards.

Turps as already mentioned.

If Eucalyptus oil hasn't worked, take it back & get them to remove it, it's as simple as that.

I always use kero cos I've got shitloads of it. Not sure if its bad but it works a treat. Then hit it with some window cleaner

Just a razor blade will do the job.
