What matters
“Natural” is not a regulated measure of cleaning performance, so compare stain removal, cost per load, scent, and how the detergent fits your washing machine. Look for clearly listed ingredients and specific certifications; fragrance-free formulas avoid added fragrance, but may still not suit everyone.
Who this is for
These picks are for shoppers who want plant-based or fragrance-free options and are willing to trade some stain-fighting power or spend more for those features. If you regularly wash heavily soiled work clothes, prioritize strong performance on grease and set-in stains.
The picks, one by one
Best overall: ATTITUDE Laundry Detergent, Wildflowers
The Filtery’s 2026 comparison names ATTITUDE its best overall and notes that the brand offers both scented and fragrance-free options. EWG Verified is a real certification; this scented Wildflowers version is also ECOLOGO certified, according to the reviewer. The Filtery reports using its listed detergents for at least a month, but this is an editor’s hands-on assessment rather than a standardized lab test. The review highlights ATTITUDE’s ingredient disclosure and range of scent options. It is a sensible fit if you want a certified, plant-based detergent and prefer scented laundry. Skip this version if you want fragrance-free; choose the brand’s unscented option instead.
Good to know: The scented formula may not suit people who prefer fragrance-free laundry.
See on AmazonBest value: Biokleen Natural Laundry Detergent, Free & Clear
The Good Trade lists Biokleen at about $0.15 per wash and describes its Free & Clear liquid as fragrance- and dye-free. EWG gives this product an A rating, and the listing links to Amazon. The Good Trade editor tried the Free & Clear version and describes it as concentrated, with a familiar measuring cap. EWG’s page covers ingredient disclosure and ingredient concerns, not stain-removal performance. A recent pricing comparison listed a 64-ounce Amazon option at about $24, though pack sizes and prices can vary. This is a better fit for routine laundry than for shoppers who need the strongest grease-stain performance.
Good to know: Independent testing found Biokleen struggled with grease stains.
See on AmazonCheapest that's still good: Rosey by Thrive Market Unscented Laundry Detergent
The Good Trade’s 2026 editor test names Rosey its affordability pick at about $0.10 per load and reports that it washed out a peanut-butter stain. Its price is clearly below the other picks. The editor tried the unscented liquid and described the bottle and measuring cap as familiar to use. The product is listed as fragrance-free, biodegradable, and three times concentrated. Its reported $0.10-per-load price is from The Good Trade, not a current Amazon listing. I could not verify that this product is sold on Amazon right now, so it does not meet your Amazon-only requirement and should not be treated as a confirmed eligible pick.
Good to know: Current Amazon availability could not be verified.
