Stinky nappies

Spencer's nappies are real stinky. I have tried use dettol inwash and hanging them outside all day in the sun and overnight when there was a frost but they still stink.
They don't stink when I first put them on him but as soon as he does wees they stink and I have to check and see if he's done poos. Not sure if he is doing stinky wees or if it the nappies.

Any ideas?

He drinks lots and the wee doesn't seem to be concentrated.

Oh good idea, will try that.

I have been using Greens Gentle washing powder (http://www.mothersinstinct.co.nz/products/Washing-Greens-Gentle-Nappy-Wash-.html) from mothers instinct for the nappies. IT is basically, baking soda, knights casteel and some oils). NO smelly nappies...the stuff rocks!!!!

I am having the same problem with smelly nappies.

Anna, how do you sanitize with tea tree oil?

I did the tea tree oil and the extra rinsing and that seems to have worked.

I wash mine at 40 degrees all the time, I'm not into this cold washing melarky that you kiwis do, and I've put mine in on 60 degrees if there has been a bit of a poosplosion that needs a bit more washing, you know the ones you rinse off but are still there It doesn't seem to have done them any harm.

I always put a couple of drops of tea tree oil into the wash anyway (I grew up 15 minutes away from Thursday Plantation and had a tea tree lake 5 mins walk from my house)

I wash at 40 too cuppatea.. to me that is a "cold" wash LOL

Right next wash they are going in a hot wash with quite a few extra rinses. FX the sun is out that day too!
