Using this tea strainer is easy. First, open the stainless steel travel box and take out the strainer. Then, add your favorite loose - leaf tea or herbs into the strainer. Place it in the ViA Heat Tea Bottle and pour hot water over it. Let the tea steep for the desired time. After you're done with your tea, remove the strainer from the bottle. If there are any tea leaves or debris left in the strainer, you can easily clean it in the dishwasher. Just make sure to dry it thoroughly before putting it back in the travel box. Store the travel box in a cool, dry place to keep the strainer in good condition. Also, avoid using abrasive materials to clean the strainer as it may damage the fine mesh.
