In the main salt is used, but as this can be corrosive to iron & steel on bridges and other metal objects Urea can be used.
Deicer works by lowering the freezing point of water, preventing ice from forming on surfaces. This is typically achieved through the use of chemicals like sodium chloride or calcium chloride, which dissolve in water and create a solution that is unable to freeze at typical winter temperatures. When applied to surfaces like roads and sidewalks, deicer helps to melt existing ice and prevent new ice from forming.
One can purchase a liquid de-icer from many sites online. These sites include Global Industrial, Northern Tool, Interstate Products, Amleo, Rewci, and Amazon.
There are several pond deicer options available for someone to purchase. Depending on the size of the pond or water source a person wants the pond deicer for, the size would make a difference.
The mineral commonly used as a food seasoning, water softener, and deicer is sodium chloride, also known as table salt. In cooking, it enhances flavor, while in water treatment, it helps remove hardness. Additionally, it is widely used in winter months for deicing roads and sidewalks to improve safety.
Deicer salt is effective at melting snow because it lowers the freezing point of water, causing the snow and ice to turn into liquid water. This occurs through a process called freezing point depression. Therefore, when deicer salt is applied to snow or ice, it helps to break the bond between the ice and the pavement, allowing for easier removal.
Calcium chloride Since it is a good deicer with less effect on plants, it may also be the "salt" referred to when someone is salting icy walkways or streets or roads.
you can but are wasting your money
Utah uses salt, sand, and liquid ice-melt on the roads during winter.

Ice has a freezing point which is generally 32 degrees and when salt is put onto frozen water it turns it into liquid. When it turns into liquid it's no longer frozen as long as the salt remains present.
Mostly glycol alcohol.
