Found this little ----bit....
What is Green Slime or Goo? And do I need to re-wire circuits with Green Slime coming out of the wires?
Also known as "Green Slime", this phenomenon is characterised by the appearance of a sticky green exudate leaking out of PVC-insulated wiring at locations such as switches, hot points and light fittings. The green goo problem is predominantly associated with older (25+ years) TPS-type cables operating in a warm environment. The exudate comprises a plasticiser that has migrated out of the PVC insulation, coloured due to reaction with the copper conductor.
Due to its stickiness and unsightly colour, the goo has a high nuisance value, however it poses no significant health hazard. It may be cleaned from surfaces by wiping with a rag soaked in a petroleum- or alcohol-based solvent (such as meths).
The long-term consequence of the exudate is that it represents a de-plasticising of the insulation, meaning that as the process continues the PVC will eventually become brittle, and crack.
