The dairying stuff is much more concentrated than household.<br /><br />Of the hydroxides which will always be present with hypochlorites, the calcium hydroxide is marginally less unfriendly (pH 12 for calcium versus pH14 for sodium hydroxide) - a bit like the difference between getting bitten by a German Shepherd, or a rottweiler.<br /><br />I've just realized something silly. The strong smell at a public swimming pool is partly rocket fuel! The ammonia from stale pee reacts with hypochlorite to give hydrazine...Keithnoreply@blogger.com
