I need to remove emulsion paint from an intercom device and phone socket
in a sheltered housing complex - someone decided to paint them and of
course they look AWFUL!!!

How long ago were they painted?

If less than a week, warm water with a spot of detergent added and a
*non* scratch scourer used gently after wetting and leaving for a few
minutes stands a good chance of getting emulsion off.

Is the appartment empty or occupied?

If empty remove the units, dismantle to get just the painted plastic
bits. Place the painted plastic bits in bowl/sink with a bit of
detergent and add hot water. Leave to soak for an hour or two. If the
paint is less than about a year old it may well just float off, 10
year old will need a little encouragement with something soft like a
finger nail or firm plastic scraper.
