We LOVE Rockin Green, it is great for nappy washes (and clothes). They are designed to rinse out easily helping to avoid detergent build up on your nappies It comes in a range of formulations specially designed for your water hardness. We are in a soft water area so have great success with Classic Rock (we just put a bit less in) and for those with hard water you can choose Hard Rock. If you don't know your water type then Classic Rock is usually the place to start. They come in a range of fabulous fragrances and are kind for sensitive skin, however you can also choose an unscented version for those with very sensitive skin.
If you are worried by smells from your nappy bucket, a quick shake of the Rockin Green pail powder helps to neutralise smells too! Fabulous products, try them you will LOVE them!
