We've been using washable nappies for over 8 months now. Lately I find that they don't smell fresh even after washing. Recently I've been washing them at 50 degrees with non-bio powder. Any advice on making them nice to use again? Is the trick to up the temperature or to change washing powder? We never used to have this problem.
I wash ours at 60 with EcoBalls and a Mag Ball (we're in a hard water area) and put some white vinegar in the conditioner section and DH says they are smelling much better (I have very little sense of smell!).
we use brown vinegar, as it was the only stuff to hand when it got rainy the other day, and it freshened the nappies wonderfully. it is esp when the cloth dries slowly that the smell of a ammonia starts to appear. good luck!
