Hi, Dottie. Citristrip has a product that is made for this. I haven't tried this but I use Citristrips other products and am very happy with them.
Go to www.citristrip.com, then "new products", then "Adhesive Remover" for some information. I don't know how available this is in your area, but you might try going to www.kleanstrip.com where they have a "contact us" feature to find a source. Citristrip and Klean-Strip are owned by the same company.
Let us know how this works. It is a common question. Henry in MI
