<p>The bite valve on my Osprey water bladder is covered in a black mould. </p> <p><a href="https://i.stack.imgur.com/f4YKK.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/f4YKK.jpg" alt="enter image description here"></a></p> <p>It's not very old and this is the second valve I've had on this. It seems to be impossible to remove and seems to grow no matter what I do. Couple of questions:</p> <ol> <li><p>Is this likely to be a health issue? </p> <ul> <li>I have used valves like this for long periods of time before so I guess not but would be interested to hear other options</li> </ul></li> <li><p>Does anybody have a good way to remove this?</p> <ul> <li>Good old fashioned elbow grease doesn't seem to shift it (doesn't help that it's very inaccessible), nor does soaking in boiling water or disinfectant</li> </ul></li> <li><p>Can anyone advise how to prevent this from happening? </p> <ul> <li>it seems to grow no matter what I do, though I admit I'm not very good at drying it out after every use... </li> </ul></li> </ol>
