I admit I am never good in chemistry even in school. Therefore, this is a question for all chemists (or chemistry geniuses).
You guys probably have heard, or have come across a product from Reckitt Benckiser called "Thirsty Hippo". Its main ingredient is calcium chloride (CaCl2).
The Thirsty Hippo is used as a desiccant to remove excessive moisture in the air. As you all know, moisture is water (H2O).
If we combine calcium chloride with water vapour (CaCl2 + 2 H2O → CaCl2·2H2O). Am I correct to say one of the by-products of these two chemicals is hydrochloric acid (HCl)? And many of us already learnt in school that hydrochloric acid is corrosive and harmful to metals.
Am I correct to say that it isn't safe to use Thirsty Hippo with our cameras and lenses?
Please verify this, as I (and I believe, many others too) are interested to know.
Thanks in advance.
