T_Bone,
I was just scanning down this thread to see if anyone had addressed the toxicity problem by suggesting MPG (Mono propylene glycol) - which is, as you say, a food grade chemical. Must not use DPG (di- version) in food grade products. Good on yer! You were the only one.
MPG is widely used as an antifreeze in, say, solar water heaters (in pipes to the heat exchanger in the domestic tank). Just that loss of density over Ca Cl2.
But, of course, for a lot of our older tractors, they used to fit heavy cast iron rims which added some weight to the outfit, but everyone wanted(?) the light "tin plate" wheels from the fifties and sixties onwards. Make "em light and then add weight... well at least there is a choice.
Screenwash contains either methanol (toxic) and propyl alcohol as antifreeze generally so everyone can choose their own poison.
Me? I would be like you and use MPG.
Regards, RAB
