Hmm...Many years ago I scattered some ordinary cooking salt onto the
concrete path around our previous house to melt ice. The concrete in
those areas then degraded quite seriously over the next few years.

I've had the same experience on the back door steps and shan't use
salt again.

It has never caused a problem when I've used it. Perhaps it's because
I swill it off after a few hours.
