Question Author
Thank you for all the helpful (and sometimes odd, Tilly?), answers. BHG, I discovered that K2R is still on the market and I ordered some yesterday. And most interesting tetrachloride can be purchased in litres and gallons, just not in a logical bottle of a few hundred mills...go figure. And crum, retro, that thawpit stuff is older than my nan! But alas, no longer available either....unless you work in a morgue!
So I shall keep my fingers crossed and revert to a Bib, as Tilly suggested, (I thought that's what my ties were for! Or so I can go back to a restaurant and hold the tie up and point to the stain, saying " I'll have some of that, please!"
So it seems we have resolved the great 'spot' conundrum of 2014. Thanbk you everyone!
