I'm having trouble with one of my metal curtain poles.
I'm using metal rings which are plastic on the inside (the bit that touches the pole).
The curtains are very stiff to draw as the rings aren't running smoothly on the pole.
I've tried cleaning the pole with a damp cloth and also with white spirit. I've tried lubricating the pole with olive oil, but it only works for a week or so.
Can anyone suggest anything I could use as a lubricant?
Thanks.
