Liquid deicing and granular rock salt both use salt to clear snow and ice. Liquid does the job with less salt, less mess and more control.
| Consideration | Liquid deicing | Granular rock salt |
|---|---|---|
| How it works | Already in solution, so it starts working on contact | Must dissolve into brine before it starts melting |
| Salt per acre (typical) | 200 lbs or less, up to 70% less salt | About 800 lbs |
| Application | Sprayed directly onto the surface | Spread as individual granules |
| Coverage | Consistent liquid coverage | Can bounce or scatter |
| Stays where applied | Stays where you put it | Gets crushed, tracked and blown off target |
| Anti-icing (pre-treatment) | Stops snow and ice from bonding | Limited |
| Curbs and stair edges | Treats vertical surfaces | Can't properly treat vertical surfaces |
| Cold weather | Works well below 0°F with brine additives | Loses effectiveness around 10°F |
| Corrosion | Up to 80% less corrosive with corrosion-inhibiting additives | Damages concrete, steel and landscaping |
| Tracking and cleanup | Minimal tracking, less post-storm cleanup | Granules get carried indoors and need cleanup |
| Application control | Highly controllable, with rate control | Depends on equipment and calibration |
Actual results depend on weather, pavement conditions, application rates, equipment, timing and operator practices. Sources: Liquid Deicing vs. Salt and the Elevate Your Liquid IQ video series from BOSS Snowplow.

Liquid deicing is the use of salt brine, or another liquid deicer, on pavement in place of or alongside rock salt. Applied before a storm (anti-icing or pre-treatment), it stops snow and ice from bonding to the pavement. Applied after plowing (deicing or post-treatment), it melts the snow and ice that is left. Brine can also pre-wet rock salt so it starts working faster. Either way, plowing goes faster and you spread less granular salt.
Anti-icing, or pre-treatment, is applying liquid before or during a winter weather event so snow and ice can't bond to the pavement. Deicing, or post-treatment, is applying material after snow or ice has built up to break that bond.
Salt brine is salt dissolved in water. The standard concentration is 23.3% salt, about 2.28 lbs of salt in every gallon of brine. That is the eutectic point, where brine stays liquid at the lowest possible temperature. Mixing stronger than 23.3% raises the freeze point.
Up to 70%. A typical contractor applies around 800 lbs of granular salt per acre. With liquids, that drops to 200 lbs per acre or less, because brine skips the step where rock salt has to dissolve before it melts anything.
Pre-treat at 40 to 50 gallons per acre, ideally 24 to 48 hours before the storm. Post-treat at 80 to 120 gallons per acre after the lot is plowed. Add 20 to 40 gallons per acre for high-moisture snow, and skip pre-treatment when dry snow is blowing.
Use straight brine above 25°F or in sun. Use a 95/5 blend of brine and additive above 15°F, a 90/10 blend below 15°F, and an 80/20 blend on sidewalks, parking decks and areas next to buildings.
No. Keep billing per occurrence at the same price. You are investing in equipment and training, and your clients get cleaner properties, faster melting and less chloride damage.
The calculator compares one season of rock salt with one season of salt brine on the same acreage. It figures rock salt at 0.5 tons per acre for each weather event, and brine at about 182 lbs of salt per acre for each event, which is 80 gallons of 23.3% brine. Annual weather events come from the region you select. Results are for demonstration only, and individual savings will vary.
A sprayer and a steady supply of brine. VSI by BOSS LiquidTech sprayers pair a gas Powerhead with a 305, 500, 750, 1,000 or 1,600 gallon tank skid, so you can match the system to your truck. Plan brine storage at two to three times your per-event use.
The 305-gallon tank fits Class 2B through Class 6 trucks, the 500-gallon tank fits Class 3 through Class 6, and the 750-gallon tank fits Class 4 through Class 6. The 1,000-gallon and 1,600-gallon tanks are built for Class 7 and Class 8 trucks.
Liability. To get bare pavement fast, contractors often spread 1,000 lbs of salt or more per acre, even though 160 to 200 lbs per acre is all the job needs. Liquids let them apply only what is needed without waiting 24 to 48 hours for results.
Studies show each ton of salt applied causes $800 to $3,000 in long-term property damage to concrete, asphalt, curbs, door frames, flooring, landscaping and structural steel. Liquids cut salt use up to 70%, and brine additives make the solution up to 80% less corrosive.
The property owner calculator figures rock salt use at 0.5 tons per acre for each weather event, and salt-related property damage at $500 per acre for each event. Annual weather events come from the region you select. It is an estimate, and actual results will vary.
Ask how many tons of salt they used on your property last season, and whether they will use liquids. Then start small: require liquid pre-treatment on parking lots and liquids on sidewalks. The Liquid Learning series for property owners walks you through it.
