Try a non-scented oxy cleaner and a good long soak with hot water.
Get a kilo of sodium percarbonate powder from one of the home-brew shops, stick a couple of teaspoonfuls in there with some hot warm water and leave it 20mins...
Top tip: TMM have a sale offer of a kilo of percarbonate and 100ml of Chemsan

Not too hot water, though. Demijohns don't like thermal shock!
Edited!
And bleach.

Once you have spent a fortune and tried everything. Get some caustic TFR.
A small ss scrubby works well too. Try a string round it. Drive it with a short length of bamboo.

In the past I have have used my usual brew cleanser VWP full strength per gallon cold water and left it overnight. 99% all muck was cleaned up.
When I used to use several DJ's at a time I bought one of these, a cup of hot water and a cordless drill had them sparking

I have had some freebies that are properly grotty, you quickly discover the difference between "recovering" these and a maintenence wash 
If you have any ceramic beads for baking, I have had decent success dropping a load of those in with an Oxi solution and swirling them 'round the glass
I recovered a very dirty DJ with warm water and Milton tablets left for 3 days when I rinsed it was spotless I did stick a bung on to shake it and forgot to remove dunno if that helped or hindered
Thanks folks. All good suggestions.
I went for the Tesco Oxy cleaner overnight.
This morning all sparkly.
Powerful stuff that Oxy.
Cheers
Matt
