I heard of someone adding vodka. But as someone who hasn't owned a car for 16 years I am loving this icey spell, long may it last.

What you need is a mixture of approx 25% water and 75% stale urine.

Add a load of ethanol or isopropyl alcohol and some eythylene glycol to water with some washing up liquid in.

Except you'll likely attract the attention of the local constabulary if you walk into a pharmacy and ask for a few litres of ethanol, and I'm not sure how much isopropyl you can buy in one go. And the easiest source of ethylene glycol is antifreeze, but last I heard that buggers up your paintwork.

...hence the vodka suggestion is less stupid than it first seems. But it would probably be cheaper to drink the vodka and get a taxi...

I've another ten litres of Holts screenwash from Costco in the garage. Rate I'm using it God knows what I'll do when that runs out...although by then the salt will likely have run out too so at least the windscreen won't turn white every ten nanoseconds...

Or its nearest substitute...beer at the KC.

Buy some meths from b&q add that to screenwash, doesnt freeze then.

Oh good idea, thanks.

Meths is allegedly unkind to paintwork - or at least to the wax which it will likely strip off (I have used meths for precisely that in the past...). I think most commercial screenwash contains Isopropyl partly for that reason and partly cos its not so toxic?

Ah, ok. Thanks for that. Back to the drawing board.

There was plenty of screen wash in Shipley Asda this afternoon

Never! They must hide it when I go in.
Ok. Thanks for that.

Yes! I have screen wash!

School shut again today. They rang me as I was arriving. So another hour and a half getting home to find its totally raining now here. Weather, weather, weather.
