Because we do not use any toxic components for our Yummy Bag, certain foods could stain or sometimes leave an odor. This will not affect the use of the Yummy Bag: you can still use it to store liquids or foods safely and freshly!
To avoid staining as much as possible, we advise that you choose a bag color that matches the content. You can avoid staining and odors by washing the bag with water and soap directly after use.
If you do experience staining, you can remove these safely by making a paste of vinegar or water mixed with baking soda. Apply the paste to the Yummy Bag and let it sit for a while. Then rinse the bag as normal. This will typically significantly reduce any staining you have experienced.
