Firstly always check what your manufacturers’ guidelines state. They know best how to look after their nappies, and you’ll maintain warranty coverage.
But here goes:
- A loose powder detergent. Why? Being loose allows you to exactly control the dose. Powder is best as liquid detergents can coat fibres and affect the absorbency. Added bonus it’s plastic-free!
- Something accessible. There’s no use choosing a detergent that’s only available from a shop 20 miles from your house. That’s not realistic or sustainable.
- Something affordable. I’m aware that what is affordable to one is not necessarily affordable to another. You’re going to be washing nappies around 3 times a week for 2+ years, that’s a lot of detergent. The cost of washing page has some indicative costs for a range of detergents if you want to compare.
- Other considerations. Allergies? Vegan? Cruelty-free?
- For me cruelty-free is an absolute essential. Sadly most big-brand detergents test on animals still (or the parent company does). Most supermarket detergents are cruelty-free. Decide what aspects are important to you and research accordingly.
I’ve dabbled with quite a few detergents over my time I’m cloth. Trying things that others rated, things on special offer, things I liked the look of. But for the past two+ plus years I’ve stuck to my supermarket own-brand without any issues. It’s cheaper priced, cruelly-free, and I can get it with the weekly shop.
