What is going to be the major difference between calcium hypochlorite and sodium hypchlorite?
Calcium hypochlorite typically produces a stronger chlorine solution as it is 65-70% in strength, whereas sodium hypochlorite is typically 10-15%.
The major difference in our exterior cleaning applications is that when calcium hypochlorite reacts with water it produces a hypochlorous acid and a calcium by-product, and when sodium hypochlorite reacts with water it produces a hypochlorous acid and a sodium by-product. This difference is key in that sodium is more soluble than calcium... ie. easier to rinse and leaves little to no residue.
