So i got an eco ball, a big one with rattle-y ceramic balls in it. I hope they are the same that are sold in the UK so you can all help me. 1. Can I add stain remover etc to the wash as well or will it affect the micro enzyme whatsits on the ceramic balls which do the cleaning, and 2. my clothes now smell of tap water. What can I put in the wash to make them smell 'clean'. I know they technically ARE clean, (except for stains on my baby whites which are tough)but they don't SMELL clean... so what do i use now?
