HI. Anyone out there know how best to clean the inside of a drinking tube from a Platy 2ltr bottle?

Soak it in Milton and then flush the crap out

Or I found oxy clean better than milton. You can also buy a specail cleaning tool but its expensive for what it is.

Never tried the oxy clean, but i used milton on a well fuzzed up tube overnight and it seems to have cleared it.
I was about to buy a new one, so it saved me £15 at least.
I think i'll keep it in the freezer now on (once all the xmas food is gone and theres some space in there).
