All Groswaddles can be machine washed at 40°C. They can be hung out to dry or tumble dried on a low setting. As with all cotton goods, we have designed our Groswaddle to allow for up to 5% shrinkage. If your child has any allergies and you wish to wash your Groswaddle at 60°C, you should allow for a little more shrinkage. You can iron your Groswaddle on a low heat if desired. We recommend that you wash dark colours separately for the first few washes. We also recommend that you wash your Groswaddle with a detergent that is free from bleaching agents in order to retain the original colours.
