Check an ice-melt temperature

Sources checked November 13, 2026: Minnesota LTAP, pavement temperature and deicer use (tables captioned MPCA) and Iowa State Extension. No interpolation. An air reading is not a pavement temperature. The 20°F rock-salt row is exact: 8.6 lb of ice per 1 lb of dry salt, 20 min listed, not a clearing-time prediction.

Above the practical reference

Practical pavement reference15°F

At 20°F, the pavement is at or above Minnesota’s 15°F practical reference for rock salt. This supports considering the ingredient; it does not predict clearing time or certify a specific product or surface.

The temperature on your bag. Your bag prints −6°F. It numerically matches Minnesota’s −6°F laboratory reference. A numerical match does not establish the maker’s definition, test method or performance. Read the product instructions or ask the manufacturer.

Your next steps

  1. Clear as much snow and ice as you can first; deicer is for loosening the remainder so it can be removed.
  2. Minnesota gives 1–4 lb of rock salt per 1,000 sq ft; its spot-treatment example of 1 lb per 250 sq ft is the upper end of that range. Follow your product instructions and conditions, then remove slush and sweep up excess.
  3. Check the surface and product instructions before use. NRMCA advises avoiding chemical deicers in concrete’s first winter and warns against magnesium-based salts on concrete.
Source notes and limits
  • Minnesota’s comparison table: at 20°F: 8.6 lb of ice per 1 lb dry salt; 20 min listed melt time. These are reference results, not a clearing-time prediction for your walkway.
  • Iowa State Extension agrees: sodium chloride is most effective above 15°F.
