If you reside in a region where the temperature drops below freezing, you know firsthand the dangers of ice accumulation. When the winter winds blow, temperatures drop, and the rain turns to sleet or snow; driveways, sidewalks, and steps become hazardous.
Although there are a host of useful commercial de-icing products available, they can be expensive and are potentially harmful to pets, plants, and paved surfaces. That said, there are a variety of cheap, eco-friendly homemade ice melt options available for your home.
Some eco-friendly, homemade ice melt solutions include:
- Rubbing alcohol and dish soap
- Wisconsin cheese brine
- Baking soda
- Rock salt
- Adding traction
Some store-bought ice melts include:
- Ice slicer
- Eco-friendly liquid anti-icing products
- Nontoxic antifreeze
Read on to learn more about how to de-ice your sidewalk and driveway to protect you and your family from a potentially dangerous fall.
Rubbing Alcohol and Dish Soap
For a quick fix, a mixture of rubbing alcohol and Dawn dishwashing liquid does the trick. The basic recipe is 5 to 10 drops of Dawn and 1 ounce of rubbing alcohol per quart of warm tap water.
Make up a quart of the mixture, and use a spray bottle to quickly de-ice small areas, or mix several gallons and pour over more extensive areas as needed. The solution works well and will not harm vegetation adjacent to the treated area.
Wisconsin Cheese Brine
威斯康星州的创新人士提出了另一种被证明有效的非常规除冰方法:奶酪盐水。Cheese brine is applied tocombat ice buildup on public roadwaysin several counties in Wisconsin. If you make your own cheese, save the brine and apply it to slippery iced-over spots when the winter winds blow.
Baking soda is a tried and true homemade ice melt used for slippery walkways and steps. Similar to salt, baking soda lowers the freezing point for ice accumulation to accelerate the melting process. Baking soda is less alkaline than table or rock salt, so it won’t damage concrete or bricks as salt can.
The most commonly used homemade ice melt solutions are common table salt, Epsom salt (magnesium sulfate), sodium chloride (commonly known as rock salt), magnesium chloride, calcium chloride, potassium chloride, and calcium magnesium acetate.
When applied to slippery surfaces, the salts mix with water from accumulating snow and form a brine that lowers the freezing point of the pavement. Sand is often mixed with these salts or chloride concentrations to increase traction.
When the highway is too icy to make it to the store safely, you likely have fertilizer stored in the shed. Alfalfa meal, urea, and ammonium sulfate found in fertilizer mixtures will help melt ice. This is a temporary solution and should not be used throughout the season as the properties of most fertilizers, while effective in melting ice, can burn vegetation and erode concrete.
Sand, granite chips, kitty litter, sawdust, or coffee grounds sprinkled on slippery surfaces won’t melt ice but will provide traction that helps prevent falls. If you go with sand,a handheld spreaderis an easy way to make sure that the walkway is thoroughly coated.

Eco-Friendly Commercial Ice Melt Products
In addition to homemade ice melt options, there are a variety of eco-friendly options you can purchase online or at your local home and garden store.
If you’re looking for a product that melts down snow and ice while enhancing surface traction, consider applying a commercial granularanti-icing blend of natural minerals such as Ice Slicer.
Available for purchase online, this environmentally friendly, noncorrosive product is a homogeneous blend of calcium, sodium magnesium, potassium, sulfur, iodine, iron, copper, zinc, manganese, and phosphorous that is effective in melting snow and ice to 5 degrees Fahrenheit.
Nontoxic, pet-friendly antifreeze, which substitutes harmful ethylene glycol for propylene glycol, issafe to use to melt ice accumulations on steps and sidewalks. Available at local home and garden shops or online, non-toxic antifreeze is sufficient for melting ice to temperatures as low as minus 50 degrees Fahrenheit.
That said, never use standard automotive antifreeze containing ethylene glycol to melt snow and ice. While it is useful for melting ice, ethylene glycol is extremely poisonous and can kill family pets that are attracted to its sweet taste.
Eco-Friendly Liquid Anti-Icing Products
If you have large areas around the homestead such as driveways or livestock loading ramps, consider buying an environmentally friendly, liquid anti-icing agricultural product. These de-icers are derived from a renewable source such as fermented grains, or the processing of sugars such as beet or cane sugar.
“Beet Heet,” available at local feed supply storesor online它比自制的解决方案稍微贵一些，但可以为环境影响严重的大面积地区提供冰控制。以碳水化合物为基础的除冰剂在零下25华氏度下有效。
A Word of Caution
If you are an organic gardener with concerns about protecting our precious planet, it is best to avoid all commercial anti-icing/de-icing products. Many commercial mixtures incorporate ferric ferrocyanide or sodium ferrocyanide as anti-caking additives. Cyanide damages the environment when it is leached into ground or surface water. Other noxious chemicals found at trace levels in some commercial de-icers, include mercury, lead, and arsenic.
Avoid using sand on sidewalks and roadways located in spots where spring rains can wash it into storm drains, ponds, streams, lakes, or wetlands. Sand clouds the water, can smother aquatic life, fills in natural marine and wildlife habitats, and can pollute waterways with contaminants like grease and oil.
