under any circumstances do not over soak the lining or it will sag.
be prepared to get wet for starters, if its really manky pre mist the lining with neat or strong mix of the shampoo your using on the fabric or g101 diluted, you only need to mist it not soak it, let it dwell for 5mins or so, then spray lightly with the machine with the extraction switched on, split your lining into 4/6 sections and work in those sections, also overlap your sections.
basically spray and suck out with the hoover at the same time, be carefull not to be too vigorous when doing this as the lining could rip/tear,
when your completely happy you've removed everything keep going over it with the hoover a few times to make sure you remove as much moisture as possible.
then close all your doors/windows etc and switch the engine on and turn your blowers up on full heat and leave it like that till its fully dry.
