This would be dependent on how allergic a person was.

I would believe it. I also believe there are people who are allergic  
to brass, copper, zinc, tin, nickel, and CERTAINLY mercury.

They make a tablet that is used to purify water in emergency  
situations. We used to carry them in Europe in the 40s. I also used  
to place a couple tablespoons of bleach in the fresh water tank of my  
old sailboat. It all comes down to an individuals constitution. I  
routinely handle pool chemicals. Some are alkali caustic, some are  
acetic caustic. I used to do a lot of cement finishing. These  
chemicals burn a lot of people. Then there are those who have no  
(perceived) ill affects.

Hmmm, misuse. How DOES one use a denture cleanser? I believe it is  
wise to rinse everything which has been soaked in anything. The first  
thing you do when you get some sort of burny stuff in your eye(s) is  
to flush them with fresh water. For the sensitive, I think a warning  
is warranted, and appreciate you bringing this to everyones attention  
as I have placed dentures in my mouth several times without proper  
rinsing and they DIS taste strange. Kinda like wintergreen.
