Our bibs are stain-resistant as opposed to stain-proof and some staining may occur as they act as a barrier between the child and the food, keeping your little one spotlessly clean underneath.  This can be the case with rich colour foods such as tomato sauce or curry.   We do have some top tips to remove stubborn stains: 1) Rub the affected area with neat dish soap 2) Pop into the machine at a one off 60 degree wash with stain remover and detergent 3) Then if possible hang out in the sunshine to dry. We do find that this will do the trick 9/10 times.
