I highly recommend a plastic scraper. Then wipe with soapy water, dry with microfiber cloth. If there is any residue or change of finish, you can wipe with a bit vegetable oil or WD 40
Mamood: Goo Gone works well
You can use Goo Gone, or soak th in water until soft and they peel off.
lemon essential oil!
Try peanut butter!
Use Goo Gone.
GOO Gone should work
Skip all of the other answers and use cooking spray like Pam or a generic works well also. Let it stand and you will be able to wipe it off with a paper towel. You can use this same technique on plastic, glass, etc.
Hi Mahmood: You can scrape off as much of the sticker as you can and then spray it with WD40. Let it soak in for a bit and then, using a a plastic putty knife, scrape off the sticker. Do this until all the residue is gone and then wash with soap and warm water and wipe dry. Good luck
