Dangers Calcium Chloride | Eva-Dry Silica Gel …
Calcium chloride makes a poor dehumidifier for gun safes due to the extremely corrosive properties of the salt. Overall, the salt eats away at the metal and rusts any metal inside the safe. When seeking boat or RV dehumidifiers, it’s a good idea to avoid calcium chloride for the same reason.

Why is calcium chloride (rock salt, CaCl2) more effective …
Calcium chloride only breaks into 2 ions, while sodium chloride does not break up and remains 1 ion. B. Calcium is a larger molecule than sodium, so it has a greater effect. C. The additional chlorine atom forms a stronger bond between the atoms in calcium chloride than in sodium chloride, so calcium chloride remains one molecule while sodium chloride breaks apart.
