<p>Half gallon jars are probably best reserved for drinking water, and they are also not very portable. Set one on your desk in the morning and you probably won’t need to refill it all day! Stay safe from chemical leach, and stay hydrated!</p> <p>Mason jar straw hole lids can have different sized holes, so be sure to double check that your straws and lids are compatible.</p> <p>The most reliable way to clean reusable straws is our straw cleaner with soap and hot water. They are also dishwasher safe, or a quick rinse might be sufficient. You can also boil these to disinfect them if you want to. My personal cleaning routine is to rinse them after use, put them in the dishwasher, then run a straw cleaner through them and rinse again before putting them away. My dishwasher usually gets them clean but sometimes leaves a little residue so this ensures they are clean.</p> <p>Before first use, clean them thoroughly with the straw cleaner and an abrasive dish sponge to remove any stainless steel taste.</p><p>Treat stainless steel straws like other metal utensils - Always supervise children. Don’t let a child move around with one, and please be careful.</p>
