Anyone got any ideas as to what strange green (almost) liquid would be in my light fittings. I was changing the usual pendant light fittings in my lounge (2, one each end in my 60's built house) for some fancy up-to-date fitments. Wen I took off the old rose pieces they had what looked liked old congealed washing up liquid in them, shich was difficult to actually was off once It was on my hands. Any ideas apart from old congealed washing up liquid? And if it was likely to be that, why?
Cheers
Mike
