I cleaned my freezer the other day (had to do in short bursts since the cold hurts my hands) with vinegar water and did wipe down some bags of veggies that still have the residue of the garlic on them... threw away several bags of frozen fruit that was burnt (ick!) so I now have more room up in the freezer.
I am using an old container for butter-like spread with holes punched in it to "breathe"... filled 1/2 way with the baking soda. I use the "smelly" soda down the drain.
It has a now "new plastic" smell to it... I can't win!
