When I get a new pair of circular needles (metal) I get out the big baking pan, put the needles in, and pour very hot to boiling water in there, let them soak for 5-10 minutes. Uncoils them pretty quickly. Your knitting will not stick on metal circulars, either. I use metal if I want it to move quickly. If the yarn itself is very slippery, I'll use wood or bamboo. And I'm pretty converted to circular vs. straight now.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
