What must the surface be verified as before applying a one-step deicing/anti-icing treatment?

Before applying a one-step deicing/anti-icing treatment, it is essential for the surface to be verified as clean. This cleanliness is critical because any contaminants such as dirt, oil, or debris can inhibit the effectiveness of the deicing or anti-icing agents. A clean surface allows for better contact and bonding of the treatment with the pavement, ensuring that it can effectively melt existing ice or prevent the formation of new ice. If the surface is not clean, the deicing chemicals may not be able to work properly, leading to reduced performance and potentially hazardous conditions.
