Thanks Rolland .. 
I wondered about that .. 

I am also going to get a bottle of that
peroxide / phosphoric acid mix at the beauty supply.
Just to try it on a scrap board .. outside per chance there
could be bad fumes .. lol just to see .. am curious ..
and at 3.00 a bottle .. cant hurt .. I guess thats why I like ferrets ..
allways curious about things .. and yes .. I heard what happened to that
curious cat.
