Using this coffee press is a breeze. First, detach the stem and basket if you've stored them in the cup. Then, add your coffee grounds to the basket. Next, pour hot water into the cup up to the desired level. Place the press on top and let it steep for a few minutes. Press down slowly to separate the grounds from the coffee. When using it to steam fish or vegetables, put them in the basket and pour some water in the cup. Heat it up and you're good to go. As for maintenance, make sure to clean the press and basket after each use. You can use warm soapy water and a soft brush to get rid of any residue. When storing, keep it in a dry place and make sure the parts are dry to prevent mold. Also, be careful not to use abrasive materials that could damage the silicone ring.
