To remove Liquid Nails from two bonded items, use a length of windshield cut-out wire to separate them. Starting at one corner, wedge the wire between the pieces. Put on gloves to protect your hands and saw back and forth with the wire until the pieces have been separated a few inches. Place screwdrivers along the gap to prevent the items from re-adhering. Continue sawing until the pieces separate.
Liquid Nails can be softened by heat or with a petroleum-based product. Using an electric heat gun or a blow dryer, heat the adhesive to 140 degrees Fahrenheit. You can also coat the material with a light layer of petroleum jelly, mineral spirits or mineral oil and let it stand for several hours or up to several days. If you need to separate two items with a wire, the friction may create enough heat to soften the adhesive.
Once the Liquid Nails has softened, scrape the adhesive off with a putty knife.
