Winter tip: Ice and salt don’t mix. Actually it’s concrete and salt don’t mix. If you are using salt or other ice melting products on your concrete walks, don’t! Contrary to stated clams, there are no products that will safely melt ice from concrete without damaging the surface. So what can done? One good way to create traction on iced concrete walkways or other iced surfaces , is to spread a coating of cat litter on the iced surface.
