Don't panic. Try to soak up the mess as soon as possible. Use a disinfectant wipe to clean the area and inside of the pocket. To prevent or treat any odor, generously dust baking soda in the pocket and over any area the milk touched. Let sit overnight before shaking baking soda out. Please note any milk, juice, or other food spill needs to be treated immediately or you may risk permanently damaging your ToteSavvy.
