Another way to disinfect anything you put in the viv is to make your own colloidal silver. Its easy to make at home and will kill most bacteria, fungi, and virii. I make a strong batch and soak anything I add to my vivs. I also have been making and taking it for years and I swear by it. Its so strong, it keeps milk from going bad, for weeks. The only thing is that if you apply the silver to the viv directly, it will kill all your good bacterias in the viv (myco).
Theres a lot of anti colloidal silver stuff on the web but its all propaganda (put out by pharma companies). I take it, have friends that take it. I know many animals that take it as well and they are the healthiest they have ever been.
Its way safer then bleach and much much stronger (against the bacterias).
