Any 'silicone' lubricant should work fine. As I live in New Zealand I doubt the brand I use will be available elsewhere in the world but silicone is silicone everywhere. Any light lubricant (i.e. not sticky and that will run into the surfaces running against each other will do. Some people have even used WD40 and said it worked well.... but I'm sure silicone will be better).
I hope this helps.
