Title: Freezing Point of 40% Isopropyl
Post by: GB Window Cleaning on December 07, 2010, 08:57:51 am

apperntly they use this in colder countries in pure water (and i would have thought trad water) to stop freezing down to as low as -20 c  :o

can anyone enlighten me? this could well be our solution!

5L is aprox £7 if I remember right. The dilution needed would be less than cost effective.
