[VAL] Oxy-Clean in Black tank?

[Dave Lowrey <airstream@xxxxxxxxxx>]

I was telling my wife about the item in the latest Blue Beret "Schu's 
News"   about adding water softener to your holding tanks to help them get 
cleaner.

She suggested adding "Oxy-Clean" to the black tank, since it supposedly 
breaks down "organic" materials.

Has anyone tried this? I wonder if it would have an adverse reaction to the 
normal toilet chemicals?
