If (more likely when!) you get breast milk or spit up on your Momzelle item, we recommend the following: As quickly as possible, soak the item in water. This is often enough to prevent a stain. If there is still evidence of milk or spit up after soaking try adding an enzyme cleaner. The enzymes in the detergent will attach the stain, literally breaking down and digesting the proteins in the milk. If traces of the stain remain, apply an all-purpose stain remover and then launder as usual. If the stain is already set into the item, we suggest applying a stain remover. The best chance of getting the stain out is to pre-treat before washing. After letting the pretreated stain sit according to the directions (but no longer because you don't want to ruin the fabric), wash the top as directed.
