When we lived in New England we had normal to soft water and I used a cloth diaper safe detergent but when we moved to Colorado and I found out that we would now have hard water. I admit that I panicked a little. I did a lot of reading about crazy laundry routines and stink issues and having a child who is already prone to rashes, I decided that I didn’t want to mess around with a wash routine and I switched to a commercial detergent. 

I have been tempted a few times to switch to a more natural detergent again but always chicken out. When I had the chance to review Molly’s Suds, I was excited to see how it would work out for us. I’ve used this detergent for a little over a month now and feel like I can now give an accurate review of how it worked for us.

About Molly’s Suds

Molly’s Suds is about as pure as it gets. It contains sodium carbonate, sodium percarbonate, sodium bicarbonate, and unrefined sea salt. That’s it! No fillers, no enzymes, no optical brighteners, no GMOs. It is biodegradable, certified vegan and cruelty-free, and is septic safe.

But does it work?

My experience:

Our test conditions: I have very hard water (it tested almost at the hardest level on a test strip), an HE top loader, and a 3-year-old heavy wetter with non-solid poo. My average load size is about 15-17 diapers.

The recommendation on the bag is to use 1 to 3 tablespoons of detergent. This would depend on your water, machine, and load size. Per these recommendations, I decided to use 3 tablespoons of detergent considering the amount of mineral deposits left behind on our dishes. I am one who believes that many people don’t use enough detergent for cloth diapers. I fell into this category for a while and we battled nasty, open rashes for a very long time so I tend to err on the side of caution and use the maximum recommended amount of detergent. 

Molly's Suds Cloth Diaper Laundry Powder Review #clothdiapers

I followed my usual cloth diaper laundry routine for the first few times using this detergent. After pulling my diapers out of my dryer I did the sniff test they didn’t smell like anything. They smelled fresh and clean without any lingering detergent odor. I was pleased with this. However, I did notice that some of my diapers had light staining. I attributed this to the fact that this detergent doesn’t have any enzymes in it where the detergent I have been using does. As long as my diapers were clean then it’s no biggie. That’s what the sun is for.

I did have one load where a couple of really poopy diapers didn’t look squeaky clean to me. My husband isn’t as thorough with the diaper sprayer as I am so our weekend loads are usually dirtier than the weekday loads where I am the sole sprayer. Because of this, I made a few slight changes to my routine to see if that would help.

  • Warm soak for an hour with 1 tbsp of Molly’s Suds
  • Cold rinse
  • Wash with 3 tbsp of Molly’s Suds on the Whites setting – extra heavy wash, hot water, drum fills 2/3 of the way, deep clean, extra rinse
  • Dry inserts, prefolds, and wipes on medium hang dry covers

The soak prior to washing has helped a lot with the staining and getting those not-so-meticulously-sprayed diapers clean. Since soaking I haven’t had any issues at all with the diapers looking and smelling perfectly clean. 

While I did need to change up my routine a bit to get the best results, overall I would say that Molly’s Suds has been a success! As with any detergent you may need to tweak your amounts and wash routine to find what works best. So if you have hard water and prefer to use a natural detergent I suggest giving Molly’s Suds a try.

    1. The most important thing to remember in my opinion is that diaper laundry shouldn’t be hard and require a bunch of wash cycles. If it is then there is something that needs to be changed. Good luck!

  11. I just recently began using Molly’s Suds for my diapers and I think it works great. I had not had any issues before, but I wasn’t using “cloth specific” detergent.

    1. My biggest piece of advice is don’t sweat diaper laundry. If a routine or detergent doesn’t work for you, switch to one that does. It’s just laundry and I think diaper laundry has been made to be intimidating when it doesn’t have to be if you have a good routine with the right detergent for your washer, water type, and baby 🙂

  17. I would love to try Molly’s Suds because it’s so hard to buy any detergent that is different than what you typically use. I’m always worried it won’t work, and since we are on a very tight budget, I’d hate to purchase something I can’t use. I’ve heard such great things about Molly’s that I think it’s worth a shot!

    1. I’m with you. The great thing is that a lot of stores sell samples of a lot of different detergents so you can try a few out without committing to a big bag
