Choosing a detergent for cloth diapers means balancing stain removal against residue buildup. Too harsh and you risk diaper rash; too gentle and ammonia odors and bacteria accumulate.
I’m Emma — the founder and writer behind Baby Bangs. I’ve spent years analyzing the chemistry and surfactant profiles of baby-safe detergents to find what truly rinses clean from cotton and bamboo fibers.
After evaluating five top contenders, the best laundry detergent for cloth diapers must be free of fragrances, dyes, and optical brighteners while still handling organic messes without stripping the fabric’s absorbency.
How To Choose The Best Laundry Detergent For Cloth Diapers
Cloth diapers require a detergent that cleans effectively without leaving residue that can cause repelling, ammonias, or rashes. Avoid anything with fabric softeners, optical brighteners, or heavy fragrances as these coat the fibers and trap bacteria.
Surfactant strength and enzymes
Look for detergents with protease or lipase enzymes that break down protein-based messes like formula or breastmilk. Too many suds can mean incomplete rinsing, while too few surfactants won’t remove solid waste from cotton or bamboo inserts.
Residue-free rinsing
Powdered detergents often rinse cleaner than liquids, especially in hard water. Free-and-clear formulas without dyes or perfumes reduce irritation risk. Always check that the detergent is specifically safe for microfiber or natural fiber diapers.

In‑Depth Reviews
1. Country Save Laundry Detergent Powder (160 loads)
This unscented powder formula is a favorite among cloth diaper parents for its ability to dissolve completely without leaving residue on cotton or bamboo fibers. The low-suds profile works well in both standard and high-efficiency machines, delivering up to 160 loads per box — ideal for families running multiple diaper washes each week.
Country Save uses biodegradable surfactants and is EPA certified, meaning no phosphates or harsh chemicals to worry about. The formula handles hard water well, so you won’t need extra rinses or fabric softeners that clog diaper cores.
Parents report that this detergent removes typical baby stains like formula and pureed solids effectively when used with a hot water cycle. Because it’s fragrance-free and dye-free, it minimizes irritation risk for babies with sensitive skin or eczema.
Why it’s great
- High load count (160 loads) reduces repurchase frequency
- Low-suds formula rinses clean from microfiber inserts
- Works in hard water without residue buildup
Good to know
- Powder may clump in humid climates without proper storage
- Requires pre-dissolving in warm water for best results
2. Dapple Baby Laundry Detergent (Pack of 2)
Dapple Baby Laundry Detergent is a liquid concentrate that earned the Clean Label Project Purity Award — a meaningful third-party certification for baby product safety. Powered by plant-based surfactants, it removes tough stains from cloth diapers, bibs, and spit-up rags without sulfates, phthalates, or synthetic dyes.
This formula is pediatrician and dermatologist tested, making it a solid choice for babies prone to diaper rash or contact dermatitis. The concentrated nature means one 50 fl oz bottle washes up to 50 loads, so the two-pack offers strong value with less packaging waste.
Because it’s fragrance-free and has no optical brighteners, this detergent won’t coat the fibers inside your diaper inserts. In testing, it held up well against typical baby messes when used on a warm or hot cycle, though heavy stains may need a pre-soak.
Why it’s great
- Clean Label Purity Award provides independent safety validation
- Hypoallergenic and safe for sensitive skin
- Concentrated formula saves space and product usage
Good to know
- Liquid may leave residue if overdosed with hard water
- Pack of two is best for families who wash diapers daily
3. Nellie’s Baby Laundry Soda (80 loads)
Nellie’s Baby Laundry Soda is a powdered detergent that includes an oxygen brightener to lift stains without chlorine or bleach. The formula is plant-based and uses naturally derived surfactants to break down formula spills, spit-up, and diaper messes while being free of synthetic fragrances and dyes.
This tin contains 80 loads, making it a practical entry-point for new cloth diaper users. The powder dissolves well in warm water and leaves no visible residue on white cotton prefolds, though parents with very hard water may want to add a water softener to prevent mineral buildup.
Nellie’s is made in Canada with concentrated powder, so a little goes a long way. It’s a good option for those prioritizing a gentler cleaning profile, though heavy-duty solid stains may benefit from a longer soak cycle than this formula alone provides.
Why it’s great
- Oxygen brightener removes stains without chlorine bleach
- Fragrance-free and safe for sensitive skin
- Compact tin packaging reduces plastic waste
Good to know
- Not as effective on set-in stains without pre-treating
- May need extra rinses in hard water areas
4. Biokleen Laundry Liquid Free & Clear (64 oz)
Biokleen Free & Clear is a liquid laundry detergent built around plant-based surfactants and grapefruit seed extract for stain removal. It’s free of fragrances, dyes, and phosphates, and it avoids common irritants like SLES, SLS, and EDTA — making it a strong choice for cloth diaper households concerned about chemical exposure.
The 64-ounce bottle is concentrated and HE compatible, so you use less per load than a standard detergent. Parents find it particularly useful for pre-treating stains because the liquid can be applied directly to diaper stains before the main wash cycle without causing fabric damage or residue.
Because it’s a liquid, some users report needing a warm or hot wash cycle to ensure complete rinsing from inserts. This detergent works well as part of a two-step wash routine where a pre-wash with Biokleen handles heavy soil, followed by a main wash with a powder detergent for deep cleaning.
Why it’s great
- Grapefruit seed extract boosts stain removal naturally
- No SLS, SLES, or EDTA for minimal chemical load
- HE compatible and concentrated for fewer refills
Good to know
- Liquid may leave residue if used in cold water only
- Not as effective on ammonia odors without hot water cycle
5. Country Save Laundry Detergent Powder (5 lb)
This 5-pound box of Country Save powder offers up to 80 loads in a standard machine or 40 loads if using the full scoop. The unscented, dye-free formula is EPA certified and uses 100% phosphate-free biodegradable ingredients, making it safe for septic systems and cloth diaper families alike.
The low-suds formulation dissolves and rinses completely, leaving no residue on cotton or bamboo inserts. Because it’s a natural powder, it avoids the optical brighteners and synthetic fragrances that can cause repelling in cloth diapers or irritation on baby skin.
Country Save works in both soft and hard water, though some parents recommend pre-dissolving in a small amount of warm water before adding to the machine. This box is also a strong all-purpose household detergent, so you can use it for the whole family’s laundry without switching products.
Why it’s great
- EPA certified and phosphate-free for eco-conscious homes
- Low-suds formula rinses clean from all diaper fabrics
- Septic safe and biodegradable
Good to know
- Smaller box may not last as long for heavy users
- Pre-dissolving needed in cold water to prevent clumping
