Drink Bottle I bought a new drink bottle today for my son. I found an instruction inside the bottle to tell me how to clean it. How complicated a drink bottle could be?! There are three parts of the lid: straw holder, valve assembly and spout. Firstly, remove the straw for best results. Turn underside of the lid up and pull up straw holder and valve assembly to separate from spout. Then rinse thoroughly. Insert valve assembly into spout, straw holder into valve assembly and straw into straw holder. (Can it be more complicated ?) Push straw up as far as possible to nest correctly into lid. The most unbelievable reminder is a sentence written in Black Bold Font and all in capital: RINSE LID IMMEDIATELY AFTER EACH USE. How could I rinse my drink bottle every time after I have a sip?
