    The use of de-icing agents is now considered a very effective measure against winter slipperiness. They lower the freezing point of water. They not only remove slipperiness by melting snow and ice. A preventive application can also prevent slipperiness or reduce the effect of slipperiness caused by less solid and therefore particularly dangerous ice. In order to ensure that the agents applied before [...]
