Are you using liquid chloride for melting ice ?
Clean Sweep liquid anti-icer & deicer is a much better choice than other liquid ice melters, that use chlorides, such as calcium chloride, or mag chloride. I'm not sure where the idea started saying that calcium chloride is safe for the environment, or non-corrosive ? Strange, because when they say that a certain ice melt product is "Salt Free" and "Non-Corrosive", those sorts of things... it is really a misnomer.
CHLORIDE. Chloride, chloride, chloride... no matter how you say it, it is still a type of salt. There's sodium chloride (table salt, rock salt... cheap stuff that's mined out of the ground). Calcium chloride, magnesium chloride, potassium chloride... they are all salts. They all are corrosive to metal, and fairly harmful to vegetation, waterways, etc. Environmentally friendly ? Nope.
Another popular liquid is "Beet Juice". Beet juice comes from canning plants, that can beets. They have waste that they want to get rid of. It's not great as a deicer at all. Mixed with a salt, like sodium chloride (there's that word again), calcium chloride, magnesium chloride, potassium chloride - then, ok, it will melt some ice. Is it the beet juice or the chloride that's mixed with it ? ... hmmm.
This is a great solution if you really want something that is non-corrosive, and environmentally friendly. It's called Clean Sweep, and used as an anti-icer you can apply only 1/2 gallon per 1000 square feet and anti-ice your entire parking area for a lower cost, and saving money on damages.
