How does it work in a fridge?

Open the box and set it on a shelf. The baking soda absorbs odors from the air. Replace it every one to two months, or when smells return.

No. It is plain baking soda with no added fragrance, so it will not mask odors with perfume.

Can I use it in a freezer or cooler?

Yes. The same open box works in freezers, coolers and lunch bags. Cold slows odor absorption, so change it a little more often.

Once it has sat in the fridge, use it for cleaning or drain freshening rather than cooking. Keep a separate box for food use.

One box suits a standard refrigerator. For a large fridge or a strong odor, use two boxes, one on each shelf.

No holder is included. A small vented container or a dish keeps the box from tipping and lets air reach the soda.
