Using your Stanley Master Vacuum Flask is super easy. First, open the steel - lined pour - through stopper and fill the flask with your favorite hot or cold beverage. You can use the vacuum - insulated stainless steel cup to pour and enjoy your drink. When you're done, close the stopper tightly to keep your drink at the right temperature.
Here are some things to keep in mind. Don't overfill the flask as it might cause spills when you open the stopper. Avoid using abrasive cleaners on the flask as it could damage the stainless steel finish. If you notice any debris inside the flask, it's best to clean it right away.
For maintenance, you can simply toss the flask in the dishwasher for a thorough clean. If you prefer hand - washing, use mild dish soap and warm water. Rinse it well and let it dry completely before storing it. This way, your flask will last you a long time and keep performing at its best.
