[GreenKeys] Simple Green, (Second thoughts)

[Richard Knoppow]

     I had no idea so many products were sold under that trade name. The 
military warning does not specify which one is bad, maybe all.
     Note that alkalies of some types affect aluminum, for instance. 
Drano drain cleaner is a mixture of sodium hydroxide and aluminum chips. 
When in water the hydroxide dissolves and attacks the aluminum causing 
the mixture to boil. It is the heat of boiling that cleans the drain. I 
am not a good enough chemist to know if weaker alkalies, like 
carbonates, can also cause trouble but sodium carbonate is also known as 
washing soda and is a common ingredient in laundry detergents. Its the 
reason that the stuff feels warm when you put some in your hand.
