In writing my previous thread (a question) I realised I needed to give a big positive recommendation for monkeyfoot wet bags! Due to space being an issue, I got two of their XL bags instead of a nappy bin. I put the used nappies and wipes in there and store them for 2-3 days before unzipping the bag and putting the whole thing in the machine, nappies and all - I never have to touch the dirty nappies as they all tumble out in the wash. The bag NEVER smells, even after 2-3 days. The bags hold loads of nappies and wipes!
