Those are useful warnings, thanks Jezza.

I checked the pH on one terrace and it was above 6 (the test kit could have been junk).
Either way I have been using it instead of salt on concrete paths and driveways.  Salt damages the concrete.  Wood Ash doesn't and works reasonably well. I still have lots from last year, it doesn't look like I will need it this year so this year's is going straight in the bin....Once it's cooled down. Note you need to clean your shoes before entering the house. Messy.
