Baking soda and baking powder aren’t interchangeable, but they’re both leaveners. Baking soda is pure sodium bicarbonate and needs an acid and liquid in your recipe to activate. Baking powder includes sodium bicarbonate plus acids and a starch, so it’s formulated to rise without additional acidic ingredients.

• Use baking soda when your recipe includes an acidic ingredient and specifically calls for it.
• Use baking powder when the recipe doesn’t include an acid and calls for it by name.
• Avoid swapping one for the other without recipe-tested adjustments, since results can vary.
• Store both in a cool, dry place and keep containers tightly closed to prevent clumping.

When in doubt, follow the recipe’s wording for the most consistent results.

Baking soda can help absorb everyday food odors inside your fridge. Here’s a simple setup:

1. Pour some into a shallow, open container or open a dedicated deodorizing box.
2. Place it near the back or on a shelf where air circulates, not blocking vents.
3. Leave it uncovered so more surface area is exposed to the air.
4. Refresh or replace the baking soda periodically, following the package guidance or whenever you notice odors returning.

Tip: Keep a separate box for deodorizing and another for cooking or baking so flavors don’t transfer. Close your food containers well, and wipe spills promptly—baking soda helps with odors, but general fridge cleanliness also makes a difference.

Baking soda is a gentle, powdery abrasive that can help lift residue without harsh fumes. Try this approach:

1. Rinse the surface, then sprinkle baking soda or make a paste with a little water.
2. Apply to the area and let it sit for a few minutes.
3. Gently scrub with a soft sponge or cloth; add a drop of dish soap for greasy spots.
4. Rinse thoroughly and dry to reduce water spots.

Before you start: Spot test a small, inconspicuous area, especially on delicate finishes or coated cookware. Avoid aggressive scrubbing pads that might scratch. It’s generally best not to mix cleaners unless the product labels say it’s compatible. Results can vary based on surface type and buildup.

If you’re working with limited space, consider how you’ll use it most:

• Shakers or smaller boxes are easy to store and handy for quick deodorizing or light cleaning.
• Standard 1 lb boxes offer a good balance for occasional baking and household use without taking up much shelf space.
• Resealable bags are great if you clean frequently and have a dedicated spot to keep them dry.
• Fridge-specific boxes are slim, designed to sit inside appliances without crowding shelves.

Keep one container just for cooking and a separate one for cleaning or deodorizing. You can browse sizes online and choose pickup or delivery to avoid extra bulk on your trip home.

Moisture and odors can reduce baking soda’s effectiveness in recipes. To help maintain freshness:

• Store airtight: Transfer to a sealed container after opening and keep it in a cool, dry cabinet.
• Separate uses: Keep one container for baking only, and a different one for cleaning or deodorizing.
• Avoid strong odors: Don’t store near spices or fragrant items that can transfer smells.
• Check activity: If you’re unsure, mix a pinch with a little acidic liquid; noticeable fizz suggests it’s still active.

If it’s clumpy or seems less active, consider opening a fresh container. Following your recipe and proper storage can help support consistent baking results.
