Oxy's great for cleaning dirty things, but would it kill the mold? Sodium percarbonate (one of the main ingredients of Oxyclean) splits up to create sodium carbonate (which is also already present in Oxyclean) and hydrogen peroxide, so the peroxide might kill the mold, but if the bag is so nasty it looks like a wig I'd be much more comfortable with a strong bleach solution than however much H2O2 the percarb in oxyclean creates.Oxy clean. Don't bleach it.
Get polyester voile curtains.Sooo... I ended up hosing the bag down to remove the hairy parts. then I put it in the washing machine with Clorox. When it was done, I ran it through the washing machine again with oxyclean.
However, some of you guys bring up a good point. I need to make a larger grain bag. I read people going to Walmart to make bags. What curtains do I need to get? I'd like it to be nylon. Can it be polyester? Anything specific?
