Since you are new round here then I'll point out that Paul Tilley is one of the most respected independent tube makers in the UK, and quite possibly the world so his advice is pretty sound!
As you probably know acetone has the potential to be unpleasant so before anyone else posts it - ensure its used in a well ventilated space, wear gloves and keep away from naked flames/sparks/heat.
The "thinners" that mollers refers to may be easier to get cheaply in large quantities if required (its car paint thinners, or even cheaper "gun wash" used for cleaning spray guns). These are also used by people on here when traditional cleaners fail. They will be at least as nasty as acetone.
