Soak'n'coke! Of course *slaps forehead* I always have plenty of that stuff in. Will try later!
I bet bringing said cola to the boil with atomiser within is even more effective! I saw the boiling-cola trick on How Clean Is Your House, cleaned the filthiest pan ever right up like new
I'm not trying surgical spirit again, left a horrid taste! At least this method goes well with Cash Cola!
