The standard
Why it made the cut
- The dual MADE SAFE + EWG Verified certification is essentially unique in the laundry category.
- A three-ingredient formula is radical in a category where ingredient lists often run to thirty entries.
- Reusable steel-and-cardboard packaging is one of the lowest-impact options available.
FAQ
Common questions
- Will it work in hard water?
- True soap performs best in soft to moderate water. In very hard water, add a water softener or run a citric acid rinse to prevent soap residue.
- Is the steel tin really reusable?
- Yes. The tin is meant to live in your laundry room for years — order cardboard refill cartons as needed.
- Are there really only three ingredients?
- Yes. Meliora publishes the complete formula; there are no enzymes, preservatives, dyes, or fragrance in the unscented powder.
