After we had had it shipped over from the Isle of Wight, my uncle found the original brass candle sconces wrapped in newspaper in his loft. They were filthy, but because they are a bit fiddly, I decided that polishing with Brasso was not going to work.
Instead I filled a large plastic tub with 2 litres of the cheapest coke I could buy. I submerged the sconces for a few hours. They came out sparkling and shiny and just needed rinsing and a quick buff with a soft cloth. I then poured the coke down the toilet to give it a good clean too!
They stayed clean for quite some time, but in honour of the move, I have repeated the process to get them smartened up for their new spot in the 'music room'!
