COMBOTHERM® Blended Deicer

Store product in a dry area, and tightly reseal after each use. To maintain product quality while in storage, solid calcium chloride must be protected from moisture. If the product is on a pallet covered by an intact plastic shroud, it can be stored outdoors on a well-drained surface. If the shroud is torn, pierced, or removed, the palletized product should be stored indoors or under a waterproof covering.

For additional information, see our Calcium Chloride Handbook.

When properly stored to protect from moisture contact, the expected shelf life for solid calcium chloride products is 36 months from the date of manufacture. Calcium chloride does not degrade or deteriorate; however, the shelf life is limited based on the potential for moisture intrusion into the product, which may cause product clumping. Solid calcium chloride absorbs moisture from the air (i.e., is hygroscopic), even to the point of converting to liquid brine (i.e., is deliquescent).

Melt Responsibly®

For the best results, follow these steps:

1. Clear the snow.
2. Set your spreading equipment to spread the calcium chloride at our recommended application rate of 28 pounds per 1,000 square feet, or 4 ounces per square yard. Refer to our Spreader Calibration Guide for setting instructions on some common spreaders.
3. Spread calcium chloride.
4. After giving the calcium chloride time to work, clear off any remaining slush.
5. Recycle the empty packaging in accordance with your local recycling guidelines.

Refer to Earth911 to find out where you can recycle.

Please note our recommended application rate is a starting point. Adjust application rate based on ice thickness and outdoor temperature. Removal of thick ice may require higher application rates to penetrate and undercut the ice layer. 

OxyChem does not recommend using deicing products on wood surfaces. Deicers could potentially soak into untreated and some treated wood surfaces, resulting in damp spots that may be difficult to remove. The variety of wood treatments used on exterior wood surfaces makes it difficult to predict the effect of deicers on those surfaces.

OxyChem calcium chloride products deliver reliable, effective deicing performance on concrete surfaces that are at least one year old and properly designed, constructed, and cured for winter conditions. When concrete meets these standards, it is better equipped to handle deicing applications. Surfaces that are more porous or not fully cured may be more vulnerable to natural freeze–thaw cycles, where absorbed moisture can refreeze and potentially lead to spalling or scaling.

For expert guidance, we recommend consulting the American Concrete Institute Committee 201.

OxyChem calcium chloride deicers are not recommended for application on masonry (stone, brick, and mortar joints). 

Melt water from deicing may soak into pores and cracks. The absorbed melt water may re-freeze, creating a large amount of pressure beneath the surface of the stone. If the structure of the stone is not strong enough to withstand this pressure, the stone could flake or powder. This type of damage depends on the porosity and strength of the stone, not on the type of deicer used to melt snow and ice. Because there are many different kinds and grades of stone, OxyChem cannot predict where damage may or may not occur. 

No chloride-based deicer is completely pet-safe, but there are a few tips you can follow to help keep your furry friends healthy around deicers.

DO:

• Apply deicing products properly. Follow directions for application and only apply as much as needed.
• Wipe your pet’s paws after coming inside.
• Consider the use of paw wax or dog booties, particularly for those pets with sensitive paws.
• Store deicing products out of the reach of pets. 

DON'T:

• Let your pet eat deicer on the ground.
• Let your pet eat snow that may have been treated with a deicer.

For further information, please see the OxyChem document, Use of Chloride Deicers Around Pets.

When following application recommendations, calcium chloride will not damage grass or vegetation adjacent to a surface being deiced. If deicers are overapplied or applied directly to grass or vegetation, damage can occur regardless of deicer type used. 

For additional information, see Deicers Environmental Impact.

Always follow the directions for proper deicer use. Do not over-apply deicer, especially near entryways. Foot traffic through slush, melt water, and residual deicer can track the material indoors. 

Use effective entrance mats that absorb and trap snowmelt, slush, or residual deicer. If residual deicer is tracked onto hard floors, it should be cleaned up with warm, fresh water as soon as possible. For example, soak a mop or towel in fresh water, wipe the surface and dry thoroughly. If a bucket is used for rinsing the mop or towel, the water in the bucket should be changed out frequently for best results.

For additional information, see Deicer Tracking and Indoor Care.

If deicers are tracked onto your carpet, quickly clean it. Most deicers are completely water soluble and are easily removed with a carpet cleaning machine using only hot water. After cleaning, it is important to remove as much of the water as possible, and the carpet must be allowed to dry.

Use of detergent is generally not recommended unless the detergent is pH neutral or citric-based (slightly acidic) and the carpet is thoroughly rinsed after washing.

For additional information, see Deicer Tracking and Indoor Care.

Yes. According the websites of three common brands (Trex®, TimberTech®, and DuraLife®), calcium chloride can be used as an ice melter on this type of decking material.
