Lime Stone Steps? Here’s What To Use to Melt Ice

ice melt for natural stone

Natural stone stairs are a high-end material that adds value to any home over time. Limestone and sandstone stairs, in particular, are eye-catching, providing depth to your house and pool areas. Natural stone is known for its durability and resistance to the elements. 

Long-term protection, especially against salt, necessitates your attention. The abrasive salt-based ice melt compounds can wreak havoc on almost any building material, including metal, concrete, and stone. Some stones are more resistant to salt attack than others; porous materials like limestone and sandstone are more vulnerable. Hence, as a homeowner, you need to know what type of salt is used on roads. You also need to understand the importance of avoiding corrosive ice melts. The non-salt ice melt is the best option for homeowners. Let us know more about ice melts safely for limestone.

How Salt Damages The Limestone?

Water’s freezing point lowers through de-icers. Depending on how much salt is in the water, the freezing point of the salty water will vary. This water will thaw and freeze periodically if the temperature increases and falls beyond the 20° threshold. 

It implies that if saline water gets into the crevices and pores of your walkways and patios, the freezing and thawing will harm the material, whether it’s limestone or concrete. As a result, when mixed with snowmelt water, it’s advisable to opt for a de-icing chemical with a low freezing point.

There are other chloride-based ice melts in the market, sold under different brand names but have the same corrosive chloride-based ingredients. They may be less toxic for plants and pets, but they are equally disastrous for your limestone stairs.

  • Calcium Magnesium Acetate (CMA)

Calcium Magnesium Acetate is a brand-new supplement on the market. It’s a water-soluble acid similar to vinegar. But only modest use is advisable. It is significantly more expensive than other ice melting methods. 

  • Potassium Chloride 

It is sold as one of the safest de-icers for pet owners. But if swallowed by pets with kidney conditions, it can be fatal. When used in moderation, it is the least destructive de-icers for plants. Furthermore, its freezing point of 15–20° is comparable to rock salt. Hence, it will not be able to prevent a freeze-thaw cycle.

  • Magnesium Chloride:

Like potassium chloride, if consumed by pets with kidney illness, it can be fatal. The freezing point of magnesium chloride is -13°.

Preventive Measures:

  • Choose the Right Ice Melt: Opt for ice melt products labeled as safe for natural stone surfaces.
  • Test in a Small Area: Before applying ice melt to a large area, test it on a small, inconspicuous spot to ensure it doesn’t cause any damage.
  • Apply Sparingly: Use ice melt sparingly to avoid overexposure to chemicals on your natural stone steps.
  • Prompt Cleanup: After the ice has melted, clean the surface to remove any residue from the ice melt.


Choosing the right ice melt for natural stone steps, like limestone, is crucial to maintaining their beauty and integrity. Opt for products like Safe Paw that are specifically formulated to be gentle on delicate surfaces while effectively melting ice.
