I have read and heard in the past that lawn fertilizer is good for using as ice melt and it will not harm concrete like salt will. I have a new driveway, sidewalk, and porch that I do not want ruined with salt. Now , does anyone know what fertilizer I should use as ice melt? I had a partial bag of 12-22-6 that I tried. It barely did anything. Made a few tiny circles in the ice here and there.
