How to Melt Ice Without Salt

how to melt ice without salt

No rock salt? It’s fine! Several excellent salt substitutes are equally effective at melting ice, and some are even more effective. Discovering methods for de-icing a driveway without salt will help you stay safe, and your property will remain in good shape throughout winter. Read on to learn some helpful tips and tactics for melting ice this winter on driveways, walkways, windshields, and sidewalks.

How Long Does it Take For Ice to Melt

When the surrounding temperature is 109 degrees Fahrenheit, an ice cube on concrete takes between 10 and 12 minutes to melt. Ice melts at varying rates based on a number of variables, including the ice’s temperature, size, and surrounding temperature.

Ice starts to melt at 32 degrees Fahrenheit, or zero degrees Celsius. Ice needs to take in enough heat to elevate its temperature to this point before it may begin to melt. How much heat is needed depends on the size of the ice. For instance, a block of ice will take longer to melt than an ice cube left outside in the sun. How quickly ice melts is also influenced by the ambient temperature.

How to Melt Ice on Driveway

It’s important to know how to clear ice from your driveway to keep everyone safe, but it’s even more important to know how to do it without salt. There are creative alternatives to using salt for de-icing, whether you’re concerned about keeping your local waters clean or your grass healthy throughout the spring months:

Dish Washer Liquid with Rubbing Alcohol

Rubbing alcohol freezes at a considerably lower temperature than water makes this technique effective. Additionally, it cannot freeze due to the chemicals in dish detergent. 

Combine 12 gallons of warm water, 14 cups of rubbing alcohol, and six drops of dish detergent in a large bucket. Spray the liquid freely on any icy surface using a big sprayer. 

Coffee Grounds

After brewing coffee, coffee grounds are frequently discarded or composted, but you may also use this organic waste to melt ice on your porch and driveway. Nitrogen is included in coffee grinds to lower the melting point of ice. Additionally, coffee grounds’ dark tint better absorbs sunlight than white snow or clear ice, helping to speed up melting slightly.

Chloride Compounds

This is available at many home improvement stores and performs best when used between zero and 30 degrees Fahrenheit. Similarly, melting ice can be accomplished with potassium chloride and magnesium chloride. Magnesium chloride works at low temperatures of -13 degrees Fahrenheit, making it an even more environmentally sound alternative to calcium chloride.

Baking Soda

Like rock salt, it lowers the water’s freezing point and reduces the likelihood of ice formation. Baking soda is less corrosive because it is less alkaline than rock salt. The most straightforward application for baking soda is manually spreading it over frozen areas.

If snow is expected, sprinkle baking soda on pathways, roads, and other surfaces to prevent ice from forming.


Vinegar contains acetic acid, a chemical compound that lowers the melting point of ice but does not melt it as well as rock salt. Like isopropyl alcohol, vinegar can be used alone in theory, but equal parts of vinegar and hot water yield the best results. Solid sheets of ice can be quickly melted by this solution, at which time they can be broken up with a shovel. Take caution to remove the resulting water from your driveway, path, or porch as you would with alcohol to avoid it freezing again.

How to Melt Ice on a Windshield

You know how difficult it is to defrost the windshield on cold winter mornings if you have to leave your car outside overnight. An ice scraper can be used, although it can be time-consuming, exhausting, and cause frozen fingers. Activating the defrost function on your car can be helpful, but you’ll likely have to wait a while for it to start working and lose petrol in the process.

Here’s what you need to do:

Pour into a spray bottle a mixture of one-third water and two-thirds rubbing alcohol. Spray the remedy onto your windshield, and the ice will instantly melt as you observe.

Rubbing alcohol’s freezing point is 138 degrees below zero; therefore, you can always keep this mixture in your car, and it won’t freeze, which is why this works.
