The girls have given you great info!!

Welcome to the world of MCN, I guarantee you this nappy won't be your last, LOL.

Being in brissy I don't think you'll have this worry with drying but I personally find my nappies come up cleaner with just a water wash.....no detergent at all, and even better if it's a warm wash. I also find that when I am using my dryer to dry the nappies they seem to start to smell after a few goes in the dryer so the sun is a great way to dry them and keep them smelling fresh!

GL!
