Top 7 Soaps For Cloth Diapers in the Market
The Best Soaps For Cloth Diapers, Reviewed
Charlie’s Soap Laundry Powder 300 Loads
Strengths
- Low-dose efficiency
- EPA Safer Choice certified
- Residue-free rinse
- High load count
- Works in any water temp
Trade-offs
- Requires precise measuring
- Not pre-measured
- Bag resealing could be better
This is the gold standard for a reason. With just one tablespoon per load, it delivers powerful cleaning across hot and cold cycles, rinses completely clean, and doesn’t contribute to diaper repelling, a major win. It’s EPA Safer Choice certified, which means every ingredient has been vetted for environmental and human health impact.
Owners praise how well it removes both stains and residual gunk from previous detergents, making it ideal for switching into cloth diapering. Compared to Rockin’ Green, it leaves less chance of buildup, and unlike strip-based options, it performs reliably in hard water. My recommendation? Start with this if you’re building a new routine. It’s not flashy, but it’s dependable in a way few others match.

Rockin’ Green Baby Detergent Unscented 90 Loads
Strengths
- Plant-derived enzymes
- Dermatologist-tested
- Biodegradable
- Vegan and cruelty-free
- Safe for septic
Trade-offs
- May leave residue in hard water
- Not a pre-treatment
- Scoop size could be clearer
If your main concern is keeping baby’s skin rash-free while still knocking out poop explosions, this is one of the most trusted names in the game. It’s plant-powered, unscented, and formulated specifically for cloth diapers, which means it rinses clean and won’t cause repelling. Reviewers note it works well even in cold water cycles, which matters when you’re doing multiple small washes.
The enzyme blend here is key, it breaks down organic matter without harsh chemicals. While it’s not a pre-soak, it holds its own against daily stains and odors. Compared to Charlie’s Soap, it has a slightly higher load count per dollar, but some users say it leaves a faint film over time if water hardness isn’t managed. Still, for families prioritizing gentle ingredients and proven results, this remains a top-tier choice.

Esembly Laundry Powder 6lbs Refill Bag
Strengths
- Mineral-based formula
- EWG Verified
- Refillable system
- pH-balanced
- HE compatible
Trade-offs
- No scoop included
- Not ideal for ammonia buildup
- Higher upfront bulk cost
This powder stands out in the cloth diaper space because it was built by people who actually washed diapers for a living. The formulation is mineral-based and avoids all the usual suspects, fragrances, dyes, phosphates, SLS, that can gunk up cloth fibers or irritate skin. On paper, it’s strong on eco-credentials with EWG Verified status, and owners consistently report it handles heavy-duty messes without leaving residue.
It’s designed to refill a reusable canister, which makes long-term use more sustainable, though you’ll need to buy the initial container separately. Compared to other powders in this list, it doesn’t have pre-soak strength like Rockin’ Green’s Funk Rock, but it does deliver consistent cleaning across regular laundry loads. I’d pick this over liquid detergents for hard water areas since mineral-based powders tend to rinse cleaner.

ATTITUDE Baby Laundry Detergent Unscented 80 Loads
Strengths
- EWG Verified
- Dermatologist tested
- Recyclable packaging
- Low irritation risk
- Budget entry point
Trade-offs
- Fewer loads per unit
- Liquid format risks residue
- Less effective on heavy soils
At this price point, ATTITUDE offers something rare: EWG Verified status in a compact, easy-pour bottle at a budget-friendly cost. It’s made with 98% naturally derived ingredients and dermatologist tested, which gives peace of mind for newborn wardrobes. While it’s marketed for baby clothes, its gentle formula works fine for full-family use too.
That said, 80 loads is modest compared to powders offering 300+, so frequent cloth diaper users will burn through this quickly. It lacks the enzymatic punch of Rockin’ Green or the deep-cleaning power of Charlie’s, but for light-duty washing or supplemental use, it holds up. I’d pick this for early-stage parents doing fewer diapers or those testing eco-detergents before committing bigger.

Tru Earth Baby Laundry Detergent Sheets 64 Strips
Strengths
- Ultra-compact storage
- Plastic-free packaging
- Easy to travel with
- Hypoallergenic
- Low carbon footprint
Trade-offs
- Inconsistent in hard water
- Limited stain fighting
- Higher cost per load
Laundry strips are having a moment, and for good reason. These take up almost no space, ship plastic-free, and dissolve cleanly in most machines. They’re hypoallergenic, fragrance-free, and made in Canada with a focus on minimal environmental impact. For apartment dwellers or travelers, they’re a dream.
But cloth diapering adds stress that most laundry can’t handle. While owners say they work fine for onesies and burp cloths, many report needing two strips per load to manage real diaper grime, and even then, performance drops in hard water. Compared to powders like Charlie’s or Esembly, they’re less reliable for heavy buildup. I see them as a niche pick: great for low-volume or occasional use, but not my first call for serious diaper duty.

Rockin’ Green Pre-Soak Funk Rock 30 Loads
Strengths
- Targets ammonia buildup
- Breaks down trapped odors
- No artificial additives
- Works on activewear too
- Septic-safe
Trade-offs
- Not a standalone detergent
- Lower load count
- Requires extra wash step
Let’s be clear, this isn’t a full-cycle detergent. But if you’ve ever opened your washer only to be hit with that sour, lingering diaper smell, this product earns its keep. It’s a concentrated ammonia bouncer, meaning it targets the nitrogen compounds left behind after urine breaks down, which regular detergents often miss. Owners consistently report fresher diapers after just one soak cycle.
Use it once a week or when things start smelling off, and it helps reset your entire stash. It pairs perfectly with milder detergents like Charlie’s or ATTITUDE that clean well but don’t aggressively tackle buildup. Unlike bleach soaks, it’s safer for fabrics and doesn’t degrade elastics over time. I wouldn’t rely on it alone, but as part of a maintenance routine? Absolutely essential for long-term cloth diapering success.

Charlie’s Soap Unscented Laundry Packets 90 Loads
Strengths
- Pre-measured convenience
- No spills or mess
- Fast-dissolving
- Hypoallergenic
- HE compatible
Trade-offs
- More expensive per load
- Less control over dosage
- Plastic film concerns
These packets solve a real pain point: measuring detergent. For busy parents juggling newborn care, having a no-mess, toss-and-go option saves mental bandwidth. Each packet dissolves fast, even in cold water, and delivers a clean-rinsing, hypoallergenic clean. They’re free from perfumes, dyes, and optical brighteners, exactly what cloth diaper experts recommend.
Compared to the powder version of Charlie’s, these are less economical per load but far more convenient. Some reviewers mention they don’t handle extreme stains as well as a double-dose powder, but for everyday use, they’re solid. I’d recommend these to caregivers who value simplicity and consistency, especially in shared households where dosing errors are common.

How We Chose These soaps for cloth diapers
As a parent and creator of NurseryDreamer.com, I understand how crucial it is to find the right products for your little one. Rather than a hands-on lab test, this research-led comparison focused on thoroughly evaluating published specifications and features of various cloth diaper soaps. I weighed owner reviews from multiple retailers alongside expert opinions from parenting and laundry blogs, applying my knowledge of fabric care and the unique demands of cloth diapering to rank each option.
For cloth diaper soaps, cleaning power and rinsability are paramount. Residue buildup can significantly reduce absorbency and contribute to rashes, so I prioritized formulas specifically designed for cloth. Equally important was gentleness; baby’s skin is sensitive, so hypoallergenic and fragrance-free options received higher consideration. A product’s ability to tackle odors, especially ammonia, also played a significant role in the final rankings.
Specifications reliably indicate ingredient lists and washing machine compatibility. However, real-world performance – how well a soap rinses clean, its effectiveness on stubborn stains, and whether it causes irritation – is best assessed through owner feedback. I paid close attention to comments regarding residue, scent issues (even in unscented formulas), and overall satisfaction. For parents dealing with particularly challenging water, finding a detergent for hard water is key, and I considered how well each soap addressed those concerns based on user reports. Finally, I also looked at compatibility with other essential baby products, like a good cloth-safe cream to prevent irritation.
How To Pick The Right soaps for cloth diapers
Choosing the right soap for your cloth diapers can feel overwhelming, but it doesn’t have to be! There are a lot of options out there, and getting it right is key to keeping those diapers fresh, absorbent, and gentle on your baby’s skin.
Effective cloth diaper soaps prioritize thorough cleaning without leaving residue. Look for formulas free of dyes, fragrances, and brightening agents. Consider the water hardness in your area, as this impacts how much detergent you’ll actually need. Enzyme-based detergents are excellent for breaking down stains, while a pH-balanced formula protects diaper materials.
Understanding Detergent Formulation
The biggest mistake I see parents make is assuming any laundry detergent will do. Cloth diapers need specific formulations. You want a soap designed to rinse cleanly, leaving no residue behind that can cause buildup and reduce absorbency. Many conventional detergents contain ingredients like fabric softeners, optical brighteners, and excess sudsers that are absolute enemies of cloth. Look for detergents specifically labeled for cloth diapers, or those that are hypoallergenic and free of those additives. Enzyme-based detergents are great for tackling tough stains, but be mindful that excessive enzymes can contribute to buildup over time, so a periodic rinse is helpful.
Considering Water Hardness
Your water’s hardness significantly impacts how much detergent you’ll need. Hard water contains minerals that interfere with the soap’s ability to lather and clean, meaning you’ll need to use more. Conversely, soft water requires less detergent. If you’re unsure of your water hardness, you can get it tested (many municipalities offer this service) or purchase a simple testing kit. Using too much detergent is a common cause of buildup, so adjusting the amount based on your water is crucial. You might find you need to use a booster with hard water to help the detergent perform optimally. For more information on maintaining your diapers, check out our guide to stripping cloth diapers.
Balancing Cost and Convenience
While a bulk purchase can seem appealing, a large container of the “wrong” soap is a waste of money. Consider the format too. Laundry powders generally offer the most bang for your buck and are often the most concentrated, requiring less per load. However, packets like those from Charlie’s Soap offer incredible convenience. Detergent sheets, like those from Tru Earth, are a good eco-friendly option, but may be pricier per load. I often recommend starting with a smaller size of a highly-rated detergent for cloth diapers to ensure it works well with your machine and water before committing to a larger purchase.
A good rule of thumb is: if you can smell fragrance on the diapers after washing and drying, you’re using too much detergent.

Frequently Asked Questions
What water temperature is best for washing cloth diapers?
Warm water (around 100-120°F) is generally recommended. It effectively cleans diapers while minimizing the risk of setting stains, and it activates most cloth diaper detergents properly. However, always check the care label on your specific diapers, as some materials may have different temperature requirements.
Can I use fabric softener with cloth diapers?
No, fabric softener should absolutely be avoided. It coats the fibers of the diaper, reducing absorbency and creating a buildup that can lead to rashes and diminish the diaper’s effectiveness over time. This is a very common mistake new parents make.
How often should I strip my cloth diapers?
You likely won’t need to strip your diapers frequently, but I suggest doing so every 3-6 months, or whenever you notice reduced absorbency or lingering odors despite proper washing. Signs like a water-repellent cover or a persistent ammonia smell indicate it’s time to consider a stripping cycle.
What’s the best way to deal with soiled diapers before washing?
Rinsing solid waste from diapers before storing them is ideal, though not always essential if you’re using a good diaper pail. For particularly messy diapers, a quick rinse or scrape into the toilet before placing them in a storage container is best for preventing odors and making washing soiled diapers easier.
Are powdered detergents better than liquid detergents for cloth diapers?
Powdered detergents often offer a better value and tend to be more concentrated, meaning you use less per load. However, liquids dissolve more readily, which can be beneficial for those with cold water washes or concerns about residue. Ultimately, the best format depends on your washing machine and water conditions.
The Bottom Line
Choosing a cloth diaper soap often comes down to balancing how much control you want over the process with how much convenience you require. While there are many excellent options, based on specifications and owner feedback, Charlie’s Soap Laundry Powder consistently rises to the top as a reliable, effective, and economical choice for most families. It delivers a powerful clean without the residue that can plague other detergents.
For parents prioritizing specific needs, the chart above offers targeted solutions. If you’re dealing with particularly stubborn odors, Rockin’ Green Pre-Soak Funk Rock is a standout. Those seeking maximum convenience will appreciate the pre-measured doses of Charlie’s Soap Unscented Packets, and for eco-conscious families, Tru Earth Baby Laundry Detergent sheets offer a compact and sustainable alternative. Don’t forget to consider proper washing cloth diapers techniques alongside your soap choice.
Ultimately, the “best” soap is the one that works best for you and your family’s needs. Don’t get too caught up in chasing the highest-rated enzyme blend or the most concentrated formula. Prioritize a soap that rinses clean, is gentle on your baby’s skin, and fits your lifestyle, and remember to always have adequate storage for dirty diapers like quality wet bags.
