use only the light colored side. the manufacturer, had a wonderful idea using the pine rosin, unfortunately, a step of straining off impurities was omited, so if you are using the dark colored side, it wont work, or worse, it will abrade your string. here's a tip, when you have a bunch of left over cakes, double broil them in a cup cake paper. this remelts and all the sediment once again settles, or you could always slow pour off the good stuff if it's worth your time, just my two pennies...
