Snow Joe Dead Sea Magnesium Chloride Flakes – 50 lb Bag
Uses a natural magnesium chloride formula aimed at snow and ice removal with a surface-conscious profile. The bag’s uniform pellets help ensure even coverage by hand or with common spreaders. Best for large concrete areas such as driveways and sidewalks, while minimizing corrosion compared with harsher chemical options. A potential limitation is handling a heavy 50-pound bag for smaller properties.
- Best for: Large driveways and concrete surfaces that require even spreading.
- Why selected: Strong ice-melt performance with reduced surface damage compared to some alternatives.
- Caution: Heavy bag weight may require multiple trips or a spreading tool for full coverage.
HARRIS Kind Melt Pet Friendly Ice and Snow Melter – 15 lb
Formulated with 100% magnesium chloride, this product is designed to be pet-friendly and fast-acting. The round pellet form reduces sharp edges, helping minimize paw irritation. It works quickly across driveways, stairs, patios, and walkways, and remains effective at low temperatures. A potential drawback is the smaller bag size, which may require more frequent restocking on larger properties.
- Best for: Pet owners needing safer deicing options for animals and children.
- Why selected: Pure magnesium chloride with a rounded pellet shape supports safer contact with paws.
- Caution: Smaller bag may require more frequent replenishment on large areas.
HARRIS Kind Melt Pet Friendly Ice and Snow Melter – 10 lb
Compact, fast-acting, and pet-friendly, this 100% magnesium chloride formulation melts ice on multiple surfaces, including steps and roadways. It remains effective in low temperatures and is suitable for owners seeking a smaller, easy-to-store option. A limitation is the smaller quantity for properties with substantial ice loads or frequent use.
- Best for: Smaller lots or controlled uses where a compact bag is preferred.
- Why selected: Consistent pet-safe composition with quick melting in cold weather.
- Caution: Limited coverage per bag—plan for more frequent applications on larger areas.
North American Salt 53851 Extreme 8300 Magnesium Chloride Ice Melter – 50 lb
Designed for larger areas that demand robust performance, this 50-pound bag melts ice and snow down to -15°F and is ready to use. It’s described as not harming carpets or concrete, making it a practical option for entryways and interior curb areas. The main caveat is the heavy weight, which can affect easy handling and storage in smaller spaces.

- Best for: Pet-friendly use on smaller to medium areas where purity matters.
- Why selected: Clear focus on safety, with effective cold-weather performance.
- Caution: Small bag size may necessitate frequent restocking on larger properties.
Ice and Snow Melt 8 lb Bag CMA Blended Magnesium Chloride
This CMA-blended formula combines magnesium chloride with calcium magnesium acetate to balance strong ice melting with surface protection. The blend aims to reduce re-freezing and be gentler on vegetation. It’s a solid choice for those prioritizing environmental impact and surface care, though it may be less effective at the absolute lowest temperatures compared to pure magnesium chloride products.
- Best for: Properties prioritizing environmental considerations and surface safety.
- Why selected: Combines effective melting with gentler effects on plants and surfaces.
- Caution: May be outperformed by pure magnesium chloride in extreme cold.
Buying Guide: Magnesium Chloride For Ice Removal
What to consider when choosing a magnesium chloride ice melt:
- Temperature range: Pure magnesium chloride often works down to -13°F to -25°F. For very cold climates, check the product’s stated low-temperature performance.
- Surface safety: Look for surface-conscious or low-corrosion formulas if you’re spreading on concrete, metal, or landscaped beds.
- Pet and plant safety: Pet-friendly options reduce paw irritation and plant damage; consider pellets with rounded edges to minimize injury.
- Bag size and coverage: Larger jobs need bigger bags or bulk options. Match bag weight to your property size and spreader compatibility.
- Application method: Uniform pellets or easy-to-spread granules help ensure consistent coverage; some products come with scoops.
- Environmental impact: Some blends minimize chloride runoff or spalling, which is important for landscaping and nearby vegetation.
Frequently Asked Questions
- What is magnesium chloride ice melt best for? It is effective for ice and snow removal on concrete surfaces, driveways, and sidewalks, with relatively lower corrosivity compared to harsher salts.
- Is magnesium chloride pet-safe? Many products are formulated to be pet-friendly, but always follow label instructions and keep pets away until the product has melted and been cleared.
- How cold does magnesium chloride work? Most formulas remain active down to about -13°F to -25°F, with some specialty blends performing further into subzero conditions.
- Can magnesium chloride damage concrete? It is typically gentler on concrete than calcium chloride or rock salt, but excessive application can still lead to surface wear over time; apply sparingly and reapply as needed.
- Which product is best for large areas? Bulk bags like the 50-pound options from Snow Joe or North American Salt Extreme 8300 are well-suited for large driveways and commercial sidewalks.
- Are blends better than pure magnesium chloride? Blends can reduce environmental impact and surface damage, but pure magnesium chloride generally provides stronger melt at very low temperatures.
