I purchased some new Haeger vases and when I got them home discovered the glue was so thick on the price tag I could not remove it with dish soap. Mayonnaise worked for me. I knew a few remedies like nail polish remover but of course did not want to damage the glaze with something so strong. I put the mayo on it then I used a toothbrush to work it into the glue. Let it sit for around 45 minutes. Go back to it, clean off with a dish sponge, one didn't come off completely so I did it again. Now it is almost perfect, might need another treatment if my son cannot rub it out.
