Every time you change the fridge/freezer baking soda – pour the old baking soda into an empty plastic coffee container with a lid. Use the old baking soda to clean. Clean drains monthly with baking soda, vinegar & boiling water. Baking soda is also a safe scouring powder for sinks, stove tops, counters, etc.
Coffee containers are great for storage & easy to label. Maxwell House has a nice handle — Folgers has a good side grip. They stack neatly in your garage, laundry room, pantry, fridge, etc. Be sure to label the contents to avoid mishaps.
