I had the same problem and did the following. Get a small bowl or jar and put some turpentine in it. Remove the nozzle from the can and drop the nozzle into the turps and leave for about a minute. This should dissolve the glue and the nozzle should come out clean. Rinse nozzle under clean water put it back on the can and continue spaying. You may need to repeat this a couple of times until your quilt is all done. Good luck.
