We recommend warm soapy water or if you want something more aggressive your normal bathroom cleaners are fine too. In South Africa we have a product called Handy Andy that is nice to use but rinse properly. Remember you do not want harsh detergents against your baby’s skin. It is always a good idea to clean new products especially for using with baby because they could be covered in residual chemicals from the factories. Most people even like to wash new clothes before using them on baby.
