Why are Natural Laundry Detergents Are Ideal for Cloth Nappies?
Cloth nappies come into direct contact with your baby’s skin for long periods. Any residue from synthetic detergents can cause irritation and may even lead to nappy rash.

How to Choose the Right Natural Detergent for Cloth Nappies?
When selecting a natural laundry detergent for cloth nappies, consider these factors. First, check the ingredient list for enzymes. Enzymes help break down organic matter such as urine, faeces, and food stains. Both The Dirt Company and B Clean Co include organic enzymes in their formulas. Second, choose a detergent that does not contain traditional fabric softeners or optical brighteners. These substances coat fibres and reduce absorbency. Third, think about format: powder tends to be more concentrated and may be more economical, while liquid is easier to dose and dissolves quickly in cold water. Fourth, look for Australian-made or sustainable packaging. Many natural detergents now offer refill options. Finally, if your baby has very sensitive skin, opt for an unscented or lightly scented option using only essential oils. The B Clean Co range of organic laundry products includes plant-based detergents, natural fabric softeners, and baby laundry liquids from many of the brands mentioned above, making it a convenient source for all your nappy laundry needs.
