The back of a mahogany vaneer kitchen cabinet, which is the underside of a breakfast bar, has had carpet glued to it. Now 30 years later the carpeting needs to come off. The carpeting itself comes off easily enough but the hard, dry adhesive does not. I would rather not sand off the adhesive because I would never get the cabinet to match the rest of the cabinets and I do not know how thick the vaneer is. Chemical adhesive removers would also remove the stain color. How can I get the adhesive off without ruining the wood underneath?
