DD's poos are covering her nappies with lovely budgie coloured stains which do not wash out. They are so bad that I'm embarrassed to put the clean but stained nappies out on our washing line to bleach them as all the houses overlook each other and everyone would see the stained nappies. Any ideas how I can get them a bit cleaner inside? I'm using one tablet of non bio per wash, rather than the recommended 2 tablets, I'm washing at a 90 minute 60 degree wash and am using mothecare sanitiser in addition to the non bio.
