Salt lowers the freezing point of water, which is why ponds will freeze in the winter, but a salt water inlet of the same size will not. By adding salt to ice (which is just water in it's solid state) it lowers the freezing point of the water, effectively returning it to it's liquid form. Usually, due to cold air being relatively dry, the water then evaporates, which gets rid of the ice altogether.

What effect does salt water have on ice?

Fresh-water ice will melt faster in salt water than it will in fresh water or in the open air. Ice forms when water molecules are cooled down enough to arrange into solid crystals. Salt will, basically, get between the water molecules and make it harder for them to form crystals.


Can garlic salt melt ice?

Garlic salt itself does not have the ability to melt ice. Ice melt products contain chemicals like calcium chloride or sodium chloride that lower the freezing point of water, causing ice to melt. It's not recommended to use garlic salt as an ice melt due to its composition and ineffectiveness for that purpose.

How can you melt ice faster whit out any heat?

One way to melt ice faster without using heat is by adding salt to the ice. Salt lowers the freezing point of water, causing the ice to start melting. Another method is to use friction or pressure to break up and dislodge the ice, allowing it to melt more quickly.
