Re; Glycol
Hi De-icer man
I read your reply to the MBA students question and I see you mention Glycol as a de-icer, I also understand there is an environmental issue surrounding Glycol, I happen to have a drum of Blue Glycol (used for car radiators) which I've had for almost 20 years sitting in my garage from a previous business, with these severe weather conditions I was tempted to use it on my paths and driveway, but was not sure as to how effective it would be and if it was dangerous in anyway, if it is ok to use, would I use it neat or watered down and if neat, will it leave blue stains on the paths and driveway, thought it might be suitable on this occasion.
Regards
Pozzy
