We use a eco egg for 2 main reasons 1 the cost and 2 allergys, they are great ive been using for 2-3 years with out problems we just add conditioner and with pet bits we just add some detol into the wash, has anyone tried them on baby bits? Is there any thing we need to know? I would hate to go back to washing powder both me and my other half have allergies to most washing powders which is why we tried the ecoegg
