If you are expecting now, recommend to send your little ones items to us 2 weeks prior to your EDD. Otherwise, you will need to do a 6 monthly regular wash to ensure the baby gear has the minimum cleanliness standard for your baby.Also, it is good to send for PramWash before and after storage. Finally, if your baby just had a little vomit, poop, pee incident, pls send it to us right away. The earlier we clean, the closer the item can get back to its original condition.
