Well, if you are re-rocking anyway, I'd use soap to get rid of the nasty stuff and any associated stench, and then move on. No need to bother with heavy-duty detergents, as any mildew, mold, urine, etc. is just going to get nicely encapsulated when you put up a new layer of drywall.

I'm a little confused, if you are re-rocking, why go through all this pain and suffering to paint? I'd get the nasty stuff with some simple strong soap (or TSP, I suppose), and I suppose if it still smelled, topcoat with BIN and be done with it. BIN will stick to just about anything, and will lock down almost any odor. (Although you do need to wear a cartridge respirator to apply it.) You probably want to apply it on a day where you can open up your house... the smell of the BIN won't stick around, unlike bleach, but it does reek while applying. I don't see any need to kill the mildew or remove the mildew stains.

And I also don't understand why you need to paint. For all of its properties, paint doesn't seal stains or odors very well at all. If you are never going to see it, don't bother applying it.

Whoops, my bad... for some reason I missed the part about the existing sheetrock being torn down. I was laboring under the assumption that the OP wanted to clean and paint sheetrock right before putting more sheetrock on top of it.

Sorry... ignore me now. (If you weren't already...:laughing
