Winter's icy grip can turn your once-welcoming driveway and walkways into treacherous obstacle courses. Though traditional rock salt remains a go-to for many, a plethora of DIY snow melt solutions exist (and most common ingredients can be found right in your own kitchen).

Look around and you'll find that homeowners use many different materials to add traction to icy surfaces. From table salt, kosher salt, and coffee grounds for instant traction on ice, to a few drops of dish soap and kitty litter, you might have success somewhere along the way. We favor spray solutions or materials that easily dissolve. Simply put: liquid and dissolvable treatments are neater, and you won't have to deal with tracking in coffee grinds into your home or staining your deck with beet juice.

Downsides of Rock Salt

While commercial ice melt remains a go-to for many, its downsides are well-documented:

  • Accelerated corrosion of metal surfaces, including vehicles, bridges, and infrastructure. This corrosion will affect the underside of your car.
  • Runoff from melted snow can enter water bodies, posing a threat to aquatic ecosystems. Excessive salt levels in water can harm fish, plants, and other aquatic life.
  • Damaging to soil structure and plant health. It may lead to soil compaction and cause vegetation to experience dehydration, nutrient imbalances, and overall stress.
  • Irritates pets' paws, causing discomfort and potential injury. Ingesting salt can also be harmful to pets, leading to health issues. Pet-safe ice melts are preferable all-around.
  • Less effective in extreme cold temperatures, typically below 20°F
  • Residue can accumulate on roads, sidewalks, and other surfaces, leading to a white, crusty appearance. This buildup may require additional cleaning efforts.
  • It's more effective at preventing ice formation than melting thick layers of existing ice. In cases of severe ice accumulation, other de-icing methods or additional materials may be needed.
  • It needs to be reapplied. It's only a temporary solution, especially during extended periods of frigid temperatures and precipitation.

Are there downsides to using calcium chloride or magnesium chloride?

Yes, there's an environmental impact. In short, calcium chloride can harm vegetation and damage carpets. Magnesium chloride, while thought to be safer for icy conditions, tends to be too expensive for frequent use.

DIY Ice Melt Alternatives to Rock Salt

1. White Vinegar

  • Vinegar reigns supreme as a natural de-icer. Its low freezing point (around 28°F) disrupts ice crystal formation, causing ice to melt.
  • Mix equal amounts of vinegar and water in a spray bottle for a simple yet effective solution. For thicker ice, adjust the ratio to 40% water and 60% white vinegar.
  • Remember, vinegar's acidic nature can dull concrete over time, so it's best for occasional use or on paths with alternative paving materials.

2. Baking Soda

  • For a gentle approach, baking soda's got your back.
  • Sprinkle it liberally on icy surfaces. While slower than vinegar, baking soda lowers the freezing point of water, gradually melting the ice. Its abrasive texture also provides traction on slippery surfaces, making it ideal for steps and walkways.
  • Bonus: baking soda is pet-friendly and won't harm vegetation.

3. Household Alcohol

  • Isopropyl alcohol, the main ingredient in rubbing alcohol, also boasts ice-melting prowess. Its low freezing point (-130°F) makes it an incredibly effective de-icer, even in harsh temperatures.
  • Combine one cup of Isopropyl alcohol with two cups of hot water in a spray bottle for a potent concoction. Mixing the alcohol with water tackles the ice layer without adding a layer of grit.
  • Note: alcohol's flammability and potential to harm plants necessitate caution. Use it sparingly and avoid contact with pets.

4. Citric Acid

  • Citric acid, found in citrus peels and commercially available in powder form, is a homemade de-icer. You probably never thought of it as a perfect ice melt!
  • Mix one part citric acid with three parts warm water in a spray bottle. The acidic nature works similarly to vinegar, but with less bite.
  • Remember, citrus solutions can also attract curious pests and pets, so keep an eye out.

Bonus Tips

  • Prevention is key. Apply these homemade ice melt solutions before snowfall to prevent ice formation in the first place.
  • Shovel first, melt second. Keep your shovel handy and clear snowy surfaces before applying homemade solutions for maximum effectiveness.
  • Use it where it matters most. Reserve your homemade deicer for high-traffic areas like steps, walkways, and slippery driveway edges.
  • Go natural wherever possible. Natural ice melt products are always best. Prioritize pet-friendly and vegetation-safe options like baking soda and citric acid. Some homeowners even use sugar beet juice.
  • Monitor closely. Reapply solutions as needed, especially after snowfall or heavy precipitation.
  • Use a carpet remnant at your entryway. Remember that many places you walk during the winter use rock salt and other harsh chemicals. Leave a piece of old carpeting near your entryway and leave your shoes there to avoid tracking it through the house.
