Buying Guide

Fragrance vs fragrance-free

Choose fragrance-free formulations like Nellie's or unscented Rockin' Green if you have sensitive skin or prefer no added scent; scented powders like Gain provide a lasting aroma

Concentrated vs standard formulas

Concentrated powders deliver more cleaning power per scoop and can reduce storage and shipping impact, while standard granular detergents like Forever New are formulated for delicate fabrics

Performance on stains and fabrics

Look for powders with stain-removal and baking-soda notes—Arm & Hammer emphasizes baking-soda cleaning power while Forever New focuses on gentle care for delicates

Environment and ingredients

If biodegradability and plant-based ingredients matter, consider plant-based, unscented options such as Rockin' Green to reduce synthetic surfactants

Cost and load count

Compare load counts and unit-price estimates—larger-count offerings like Gain and Rockin' Green can lower per-load cost for frequent laundry routines
