A Note about the Lifespan of Mason Jars Glass mason jars themselves can be used almost indefinitely. As your baby outgrows bottles, you'll be able to use these jars for baby food storage, toddler cups, or a million other things around the house. However, mason jars come with metal lids and collars which are not meant to last a lifetime. These metal two-piece lids are designed to be used for canning, and as such, are not meant to withstand repeated trips through the dishwasher. Please note that mason jar lids do tend to rust over time. Dry them carefully to extend their life. If you ever need new lids, you can easily replace them at a local hardware store, or anywhere mason jars are sold. You Might Also Like The Mason Bottle DIY Kit, if you already own mason jars at home.
