Diapers can hang onto odors and residue long after a regular wash cycle calls it quits. This simple homemade disinfectant cleaner gives you an easy pre-soak for nappies before they head to the laundry room proper. It takes a minute to mix, and your washer gets to do the heavy lifting after that (as it should).
A homemade batch can cost less per use than many store-bought diaper soaks or specialty laundry additives, especially when you’re working from pantry basics and a bottle of household ammonia. Just as important, you control the exact mix and skip extra fragrance, dyes, or add-ins you may not want in a diaper soak.
You only need 3 materials for this batch: baking soda, warm water, and ammonia. The formula is mixed right in a bucket, then used as a soak before laundering as usual, so the only equipment you genuinely need is that soaking bucket and your regular laundry setup.

How to Make Homemade Disinfectant Diaper Soak
- Pour the warm water into a bucket.
- Add the baking soda and ammonia.
- Combine the mixture in the bucket until blended.
- Soak diapers or nappies in the solution.
- Launder as usual after soaking.
How to Use It
Use this mixture as a pre-soak for diapers or nappies before washing. It is not presented here as a leave-on product or a general all-purpose household spray, so keep it in its lane and use it for the soaking step before laundering.
If you want a broader homemade cleaning option for everyday messes, take a look at Triple Action Multipurpose Cleaner. For another diaper-related laundry helper, Diaper Pre-Soak is worth bookmarking too.
Safety Information
Mix and use this soak in a well-ventilated area, and keep it away from children and pets. Do not combine ammonia with bleach or chlorine-based cleaners. The CDC specifically warns that mixing bleach with ammonia can release dangerous fumes, which is one household shortcut nobody needs to try when handling ammonia around the house.
Use the soak only as mixed here, and rinse your bucket well before using it with any other cleaning product later.
Cost Breakdown
This is a budget-friendly batch, but prices vary by store, brand, and bottle size. A reasonable estimate for the consumable materials only comes in at about $0.48 per batch, based on typical current pricing for baking soda and household ammonia, with water treated as a negligible household utility cost.
- Baking soda, 1/2 cup: about $0.16
- Ammonia, 1/4 cup: about $0.32
- Warm water, 1 gallon: not materially calculated
