Perhaps it all hinges on the word "Compound". The drug store(Shoppers Drug Mart, a large Canadian chain) also sells "Rubbing Alcohol" and I seem to remember it being isopropyl alcohol.
The WWF had frozen up in my Sierra (an ongoing problem anytime the fluid has not been used in weeks and there is a sharp drop in temperature. I keep reminding myself to use the WWF system just before a cold spell) and I added a bottle of the Rubbing Alcohol Compound tothe reservoir. The next day the WWF system thawed out and I was able to use it again. I can't be positive it was the alcohol that did it since it also coincided with a break in the cold spell with the temperature lows going from -15C to -2C. Also, I think the freeze-up must be occurring at the nozzles with the alcohol content evaporating out and rain water getting in and alcohol poured into the reservoir probably has no effect on the fluid near the nozzles.
