Can Cloth Diapers Be Washed With Other Laundry?

FAQ

It’s probably a coincidence, but I’ve had a bunch of people ask about part-time cloth lately, right when I find myself with a daytime-potty-trained toddler and only nighttime bedwetting pants to wash. In both cases (part-time cloth or potty training your youngest/only child) you’ll have very few cloth diapers to wash and probably wonder if can you wash cloth diapers with other clothes.

So, can cloth diapers be washed with other laundry? Yes, you can wash cloth diapers with your regular laundry. With that said, cloth diapers are different from other types of laundry in some important ways and so you may want to carefully consider what laundry you wash them with, and when you will add them.

How is Cloth Diaper Laundry Different from other Laundry?

Cloth Diaper laundry is different from regular laundry in two key ways:

1. They’re a different level of dirty.

Dirty clothes are usually just dirty on the outside. They have food or dirt on their surface only. Occasionally clothing with have sweat penetrate their inner layers, but clothes are often thin, single-layer pieces of material, and the sweat isn’t in great quantities.

Cloth diapers on the other hand are thick, multi-layered products and the dirt (urine) is sucked into it by design. It needs to be cleansed inside and out. This is why cloth diapers need to an extra rinse at the start of their washing process, to begin the process of removing the urine from inside the diaper layers.

2. They can’t be stored for as long.

Dirty clothes can be stored in open laundry hampers, and because they are thin and lightly soiled, they dry out and can then sit waiting to be washed for days or even weeks at a time.

Cloth diapers on the other hand are often soaking wet when put aside until laundry day. Because urine does naturally have a smell, many parents opt to store them in a zipped wet bag or diaper pail where air-flow is minimal.

Depending on what storage method you choose, cloth diapers should be washed either every 1-2 days or every 3-4 days to keep bacteria and mildew/mold from growing.

If They’re so Different, Why Wash them Together?

Good question! Though there are big differences between cloth diaper laundry and regular laundry, which I just described, the benefits of washing them together are even bigger when you’re not using many diapers at a time.

To get diapers truly clean you:

A) need to wash them with other diapers or items to agitate against them, in essence scrubbing them a bit, and

B) need to wash enough of them to meet your washer’s minimum load requirement (and also not exceeding your washer’s maximum capacity, but we’re worried about small loads right now).

I have a full article about how to wash cloth diapers here, in it, I tell you exactly how to figure out your washing machine’s exact load capacity so that you’re not under-loading or over-stuffing it. I strongly recommend checking that article out. But in essence, if you can find out your washer’s cubic foot measurement, you just want to make sure you’re putting in one pound of laundry for every cubic foot as a minimum, and three pounds of laundry for every cubic foot as a maximum. This is especially important for HE washers that weigh your loads for you and use as little water as they can to save energy.

If you have a non-HE, old-school washer, you can get away with a bit more. All you have to do is aim to have your washing machine look like a big pot of stew once it’s full with laundry and water. You can read more about cloth diaper stew here.

When you don’t have many cloth diapers to wash this is of course a problem. As mentioned earlier, cloth diapers need to be washed every 2-3 days at maximum to prevent mildew (mold) and bacteria build-up, so just waiting until you have enough to wash together is not a good solution.

Adding other laundry, like towels, other dirty clothes, etc., is a great way to still give your diapers the agitation they need to get clean, within that 2-3 day window before mold and bacteria is a concern.

What Items Shouldn’t I Wash With My Cloth Diapers?

Here’s a quick video that outlines what laundry to avoid washing diapers with, and how to wash them. If you’re next to a sleeping baby, you can continue reading all of that information below the video:

When I started washing my cloth diapers with other laundry, I was very choosy about what laundry I put with them. My husband is in construction and regularly comes home muddy and covered in glues, wood chips and other nasty things that I didn’t want traces of against my child’s nether regions.

To get you thinking about what kinds of laundry you don’t want to add to your cloth diaper loads, here’s a short list of items that aren’t ideal:

How to Wash Cloth Diapers with Other Laundry

As I touched on above, cloth diaper laundry washing routines include an extra rinse at the start to help clean urine out of the inner layers of diaper fabric.

This extra rinse is often overkill for regular laundry as dirt is usually on the surface.

I recommend beginning loads of mixed laundry (diapers and regular laundry) by doing your initial rinse or small wash cycle on only the diapers and then adding in the clothing just before your main hot wash cycle. This is because while cloth diaper agitation is key to deep cleaning, during that first cycle of diaper laundry, more water than laundry is not a bad thing, and it may actually help rinse more urine away as it won’t be able to attach itself on the clothing before it’s all washed, which is the point of that first rinse/light wash.

Now, while that’s what I recommend, it isn’t what I follow. I currently own a HE top loader that gives me the option of adding an initial rinse, and an additional final rinse with the push of a button. This allows me to dump in everything, push a few extra buttons and forget about everything — I’m lazy enough that that option is what I choose every time I can. All my clothes and diapers come out nice and clean together regardless. Do what works for you if you have a simple option like this.

If you decide to add laundry to your diaper wash after the initial rinse, make sure to follow your cloth diaper wash routine for the remaining wash and rinse(s) including detergent and heat settings. When it’s time to dry, you can once again separate the laundry or continue to follow your cloth diaper drying routine if drying them together in a dryer. (Yes, you can dry cloth diapers in the dryer as you can read about here).

Conclusion

If you don’t have enough dirty cloth diapers to make up a load of laundry, washing them with other laundry has a ton of benefits and doesn’t affect the cleanliness of your laundry at all. As long as your diapers are following their same wash routine, all the clothes you wash with them will come out nice and clean, and the diapers themselves will come out much cleaner than they would if you had waited too long to wash them, or washed just a few at a time.  

Next Step

Now that you have a green light to wash your diapers with other laundry, and know some basic rules to follow to make sure that you don’t have any hiccups doing so, it’s time to think about how to wash that laundry.

An important first step is choosing a laundry detergent that’s safe for cloth diapers. It’s important to use cloth diaper safe detergent even if you’re mixing those diapers with other laundry.
