Whats the best way to remove stickers that won't shift with your nail?!

I've got 2 big Sigma stickers (no point in keeping them, I've replaced it with a Clifford Concept 650 instead) that literally refuse to shift, I'm thinking of burning them off but not sure this is a great idea

hair dryer and meth spirits

Razorblade and glasscleaner.

Whats wrong with sticker-removal-stuff?

Id be real careful with the razorblade->scratches

the best has got to be thinners/white sprit!!! just wipes the glue right off,just damp a cloth with it an start rubbing...

Aceton?

Razorblades are totally ok if they are fresh and you don't stab the window.. It's actually what pro recond's use.

Thanks for the advice guys ..

I purchased some "Goo Gone" spray and some razor blades .. they are totally ok as they have fine enough blades to get underneath the sticker without scratching the window.

a bit of elbow grease and goo gone, and the sticker has been completely removed.

Time now to find some Clifford stickers on ebay!
