Hi,<br><br>It looks like I have the real Jungle canteen "only" teh instructions like you talked about are printed on the OD colored canteen cover (at the back).<br>The mesh screen (debris filter) is in the spout and is chrome colored but not magnetic so I expect it to be brass with nickel coating.<br>I'll try rinsing the bag with some false teeth cleaning tablets in the luke warm water.<br>I normally clean thermos bottles and so on using this technique and it works perfectly.<br><br>I will let you know if this solves the problem.<br><br>Best Scouting wishes from Holland,<br><br>Bagheera<br><br>
