Why? I hear u ask? .....erm just because! My word am I glad I did though! The right hand side was fine, came out looked clean, nothing sinister inside so I put it all back. Then repeated on the left. Yuk what can only be described as a wet, brown, diarrhoea like substance started to run out from inside the tube :bad:
Somehow water must have got inside and gradually turned into rust soup as it couldn't then dry. No idea how it got there coz I can't find any obvious way in there.
So after 45mins of cleaning out the inside (another of the kids toothbrushes ruined) I gave a protective spray of wd-40 and put it back together.
ummmm yummmy :bad:, never seen that happen before, knw the weights can rust on but thats crazy ,
