Got mt my new license tab stickers here in Minnesota and they wouldn’t stick. It was January and 25 degrees. After cleaning over the two old tabs, there was still no way they would adhere. Took them inside and let them soak with hot water in the kitchen sink. Dried and cleaned them, then used a small knife to remove the old stickers. Then used paper towel with alchohol to get as much of the old adhesive off as I could. The new stickers then went on very easily.
