Transparency (20%): Does the brand disclose ingredients, sourcing, and manufacturing?
Durability (20%): How long does it last? Longer-lasting products reduce plastic waste over time.

Conventional cleaning products contain synthetic fragrances (a mixture of up to 3,000 chemicals), chlorine bleach, ammonia, and other harsh chemicals that off-gas into indoor air. Indoor air quality is often 2-5 times worse than outdoor air quality due to cleaning product residues. Children playing on floors are most exposed to cleaning product residues.
Why We Rated It This Way
Arm & Hammer baking soda is pure sodium bicarbonate — no synthetic chemicals, no fragrances. A safe, effective cleaning agent for dozens of household tasks: scrubbing, deodorizing, laundry, and more. One of the most versatile and safest cleaning products available.
