I've used non bio for ever, my mum used it when I developed Excema when I was 12 and when I set up home myself it's all I've ever used.
Recently my washing machine has been STINKING. I've done a bit of googling research and it seems that non bio washing products and low temps might be to blame. I have tried putting my washing machine on a hot emty load with vinegar (usually keeps smells at bay) but it wasn't cutting it.
I bought some bio powder today and my machine is currently on a hot wash. It smells lovely!
My skin has settled down, my excema is hormone related so powder isn't going to affect it. I do have a new baby though. Do you have to use non-bio?
I just think non-bio doesn't smell as good and you don't get all the choice you get with bio.
Hopefully a couple of washes will solve my smelly machine problem!
