My mom gave me this great recipe to take off any sticky residue from tape, sales stickers etc.
2 parts baking soda to 1 part vegetable oil
Dab it on with a paper towel, let it sit for about 10 minutes and then just rub away the stickies... repeat if necessary.
My mom used this to remove the residue leftover tape residue from double-sided tape that was left on her floor after she pulled up a piece of carpet that was adhered to her floor with tape.
This recipe would be perfect for any sticky residue.
