Thanks, I will try those - I knew about lecithin and was thinking about trying that next, but I might do the vinegar first (as long as it doesn't sting - I tried opening it again tonight to get the white stuff out!! Might have to wait for it to heal a wee bit before sticking mild acid on it!). Luckily no milk is getting backed up because the duct itself is open, but there is still a white head on the top of it. Argh!
