Good morning, I am posting this for our Historic Site Director. I will forward any comments to him and if anyone would like more information, I can put you in touch directly with him. We are looking for ice melt or ice-inhibitor that will not damage or build-up on historic stone and tile surfaces. Any suggestions? We are considering Ice-Clear(r) that is a carboxylate-carbohydrate blend (their desc.) and I am unsure if this will absorb into and affect the surface of historic stone or tile as salt and sand do. This product is attractive because it is advertised to be harmless to plants, and the surfaces we need to keep clear are lined with beds. Any advice appreciated... Thank you!
