Formalin??

[Arabryder <Arabryder@aol.com>]

I missed part of the formaldehyde thread but did see mention of formalin.
I've been using a product called Thrush Buster.  Ingredients (in order) are:
water, isopropanal, formalin, P.V.P iodine complex, gentian violet.  

Is anyone familiar with this product?  Considering the thread, I'm wondering
whether I should continue to use it?
