The wrong detergent leaves cloth diapers smelling less-than-fresh after a few months — trapped ammonia and bacterial residue, not a stain issue. Finding a formula that cuts through human waste without stripping fibers or causing skin irritation is the real challenge of this narrow category.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent hundreds of hours analyzing surfactant profiles, enzyme types, and mineral-based cleaning mechanics to identify which detergents actually prevent buildup in cloth diaper fibers.
After cross-referencing ingredient lists, EWG certifications, and real-world wash routines, I’ve narrowed the field to the five formulas that genuinely work. This guide covers everything you need to know before buying detergents for cloth diapers.
How To Choose The Best Detergents For Cloth Diapers
Cloth diapers require a detergent that removes biological stains and ammonia without leaving behind residue that traps bacteria. The wrong choice leads to repelling, rash, and odor that worsens over time. Focus on these three factors when comparing products.
Enzyme Activity Level
Enzymes like bromelain, protease, and amylase break down the proteins and starches found in human waste. Powdered detergents often carry higher enzyme concentrations because the ingredients remain stable longer in dry form. Liquid detergents tend to have lower enzyme payloads, which makes them better for daily maintenance rather than deep stripping sessions.
Mineral-Based vs. Surfactant Cleaning
Mineral-based powders rely on carbonate and silicate chemistry to lift soil without coating fibers. Surfactant-heavy formulas can leave a waxy film that reduces absorbency over time. If you wash cloth diapers exclusively, a mineral-based powder is generally safer for the long-term health of the fabric.
Water Hardness Compatibility
Hard water requires a detergent with built-in chelating agents or the addition of a water softener like borax. Soft water systems benefit from low-sudsing, clean-rinsing formulas. Check whether the detergent is pH-balanced and HE-compatible to avoid oversudsing issues in front-load machines.

In‑Depth Reviews
1. Esembly Washing Powder (3lb Canister)
Esembly originally formulated this mineral-based powder specifically for cloth diapers, and the chemistry shows in the results. The carbonate and silicate base lifts biological soil without leaving a surfactant film that reduces absorbency. It is pH-balanced and clean-rinsing, which means you do not need a separate stripping cycle after every bulk wash.
The powder is fragrance-free, dye-free, and free of optical brighteners and phosphates. EWG verification confirms that none of the ingredients trigger the health or environmental flags that often pop up with conventional detergents. Many users with hard water report pairing this powder with borax to maintain zero stains and no ammonia buildup across months of daily use.
One scoop per load is enough for heavy soil, and the 3lb canister holds roughly 48 scoops. If you have multiple children in diapers, the refill bag option offers better value. This powder works for the whole household, not just diapers — towels, activewear, and bedding all come out residue-free.
Why it’s great
- Mineral base prevents absorbency loss over time
- No fragrance or dyes to irritate baby skin
- Works in HE and non-HE machines equally well
Good to know
- Bulk refill bag zipper may break; transfer to a sealed container
- Slightly higher cost per load than budget liquids
2. Earthley Wellness Laundry Detergent
Earthley uses bromelain, a pineapple-derived enzyme, to target the protein-based stains that come with cloth diapering — blowouts, spit-up, and urine residue. The concentrated powder requires only half a tablespoon for a regular load, which makes the 90-load bag stretch far longer than the advertised count. The formula contains no optical brighteners, phosphates, sulfates, or preservatives.
The scent is mild and fades completely after drying, which is important for babies with sensitive noses. Users report that clothes come out soft and static-free without needing dryer sheets. Because it is peroxide-free, it is safe for colored diapers and covers that might fade with chlorine-based stain treatments.
The packaging is a simple resealable bag, and some users have reported torn bags during shipping. Transferring the powder to a mason jar or dedicated canister solves the storage issue. This detergent is best for households that prioritize enzyme cleaning over mineral-based mechanics.
Why it’s great
- Bromelain enzyme tackles organic stains effectively
- Very low dosage per load maximizes value
- No residue or buildup on diaper fibers
Good to know
- Bag packaging is prone to tearing during transit
- Mild scent noticeable before drying may not suit all preferences
3. Esembly Washing Powder (6lb Refill)
This is the same mineral-based washing powder from Esembly sold as a 6lb refill bag — the most cost-effective way to stock up if you already own the canister. The formula is identical: fragrance-free, EWG Verified, and designed to rinse clean without leaving the residue that causes ammonia buildup and repelling in cloth diapers.
Users with hard water continue to report success pairing this powder with a water softener like borax, achieving zero stains and no lingering odors even after years of full-time diapering. The bag does not come with a scoop, so you will need to reuse the one from the canister or measure with a standard tablespoon.
One refill bag lasts roughly five to six months for a single child in cloth diapers, making it a solid long-term investment. The bulk packaging reduces plastic waste compared to buying multiple small canisters. This option is ideal for families committed to cloth diapering full-time.
Why it’s great
- Lowest cost per load in the Esembly lineup
- Same proven mineral formula as the canister
- Sustainable refill packaging reduces waste
Good to know
- No scoop included — reuse an existing measuring tool
- Bag zipper may fail; store powder in a sealed container
4. ATTITUDE Baby Laundry Detergent Refill
ATTITUDE delivers an unscented, plant-based liquid formula that is EWG Verified and made with 98% natural-origin ingredients. This detergent shines for families whose babies have eczema or hypersensitivity to fragrances and preservatives. Multiple reviews confirm that switching to this detergent resolved skin flare-ups that persisted with conventional baby detergents.
The formula works in all water temperatures and is safe for both standard and HE machines. It handles light to medium stains effectively, but heavy biological stains from cloth diapers may require a pre-treatment or a longer wash cycle. The refill box uses significantly less plastic than a traditional jug, which aligns with eco-conscious household goals.
Users note that the box packaging can arrive damaged, and the refill bag inside lacks its own product label — so labeling the bag after transfer is wise. At 80 loads per box, the per-load cost sits in entry-level territory for a non-toxic detergent. It is a good choice if you prefer liquid over powder and want a certified clean ingredient list.
Why it’s great
- EWG Verified and safe for eczema-prone skin
- Plant-based, vegan, and cruelty-free formula
- Refill packaging reduces plastic consumption
Good to know
- Heavy stains may need pre-treatment
- Box packaging can arrive damaged in transit
5. Dreft Baby Liquid Laundry Detergent
Dreft is the conventional benchmark for baby laundry in the mass market. The liquid formula is dermatologist tested for sensitive skin and contains no added chlorine bleach or dyes. It handles common baby stains like spit-up, milk, and blowout residue with a 3-in-1 approach that fights odors, removes stains, and stays gentle on skin.
The classic baby-fresh scent is strong and lingers on clothes after drying — some parents love this signature smell, while others prefer unscented options for cloth diapers. Because Dreft contains surfactants typical of conventional liquid detergents, long-term use on cloth diapers may require periodic stripping to prevent buildup that reduces absorbency.
With 114 loads per jug, the value is straightforward for households that wash baby clothes and diapers together. Works in all machines and water conditions. This detergent is best suited for families who use cloth diapers part-time or who prioritize the nostalgic Dreft scent over the stricter performance requirements of full-time cloth diapering.
Why it’s great
- Trusted brand with decades of safe use history
- Large 114-load jug offers great value
- Effective on common newborn stains
Good to know
- Fragrance lingers strongly on fabrics
- May require periodic stripping for cloth diaper absorbency
