Bluecol Sub Zero De-icer is a powerful and fast acting spray formulated to defrost windscreens down to -25°C
Bluecol has been protecting engines for over 70 years. In the 1930's, Smiths Industries developed Bluecol as the first all year round antifreeze. For years Bluecol was the manufacturer's standard fill in many cars, trucks and buses. Today there is a Bluecol range to suit commercial and domestic users.
Can only agree with other reviewers. This melts the ice - even the stuff you can't scrape - really quickly. No need for a second spray for the stubborn patches either, unlike a cheaper brand I had been using.
