Buying Guide
What should you consider when choosing bulk bicarbonate of soda? Here are practical questions to guide your decision.
- What is the intended use? If you need pool buffering, a product marketed for alkalinity up may be preferable. For cooking or cleaning, a high-purity, food-grade version is ideal.
- What size is practical? Large 50 lb bags or pails suit frequent users; smaller households may benefit from gallon containers or multi-pack boxes.
- Is organic certification important? If you prefer OMRI-certified or aluminum-free formulas, look for Unearthed or similar organic labels.
- Are there storage considerations? Bulk bags require sealed, moisture-proof storage. Keep away from humidity to prevent clumping.
- Do you need multiple uses? Baking, cleaning, deodorizing, and pool maintenance are common, so select a product with broad applicability or separate products for specialized tasks.
