Step 1: Clean all parts of the cup before use.
All parts are top rack dishwasher safe, or can be handwashed. Fully disassemble parts before washing (remove the valve, straw part and unplug the straw valve). For Spout cups, store the valve under the lid when washing in the dishwasher. Do not use abrasive cleaners. After washing, allow cup parts to dry thoroughly between uses.
Step 2: Assemble the cup.
Sport Spout: Push rectangular end of valve through matching hole in lid. Insert flip-open spout into slots in lid. Inset straw. Press round vent cylinder firmly into small hole in lid.
Step 3: Closing the lid.
Screw lid onto cup, clicking clockwise until tight.
