Yes, Nigel, and a very good way to remove stains. But it's the rigmarole afterwards with the soaking water poured reverently onto bare earth that makes me cross.
Ah, the Oxford Movement! Very High Church Anglicans, and good luck to them, but I don't subscribe to it. 'Cranky Hanky' is a good way of putting it, ChanteyLass.
Our church collects non-perishable food for the Food Bank at a nearby town. Some of us put tins etc in a big box which is taken there every week. Now instead of getting one's knickers in a twist about a holy hanky, it might be a better idea to concentrate on what are obviously poor folk with no food at all, who need emergency boxes ( a three-days' supply) I do my best, but there is obviously a great need out there for a more practical Christian effort in helping and relieving need. I imagine Jesus would agree.
