Hi,

I would add a couple of points--

We always cleaned the items before sealing them in the bags.

Make sure that you don't have so much in a bag or in the box that would keep all the items from freezing quickly. You don't want the items on the inside to be shielded from the cold.

We removed the items from the freezer, let them rest for several days and then repeated the treatment.

Finally, be sure to clean the items again once the freezing treatment is complete.
