It is always a good idea to make sure that ice on your concrete is melted when it is used by traffic from people and vehicles. It is important to make sure that if you are using an ice melt product, that you are careful what ones you use. Especially on stamped concrete.
Salt alone at the least can cause stains and can react with the dyes in the concrete and bleach the surfaces. It also can contain chemicals that can eat away at the concrete causing it to break down. non-salt based chemicals are available for concrete driveways. Sand or kitty litter are your best options. Some of the pet friendly de icers may be ok also stay away from ones that contain ammonium sulfate or ammonium nitrate.
