Clicky PB hinge

I've had my Rev C 12" PB since just after they appeared. Over the past couple of weeks I've noticed that the when I'm opening and closing (though opening is far worse) that it's almost sticking... and so when I move it it kinda clicks. Basically it seems to me that it just needs some lubricant (WD40?), but I don't want to do anything to upset the careful balance within the sacred PB.

It definitely doesn't seem that anything is actually clicking, as it doesn't happen in any particular position, just whenever I'm opening it up.

Is it safe for me to apply something to keep it opening smoothly?

Thanks guys

 

Cool... I'll maybe just do that.

Thing is, it didn't do it at first... kinda developed. However, I find that often little problems with technological things develop and then un-develop all of their own accord... little creaks and noises which you notice for a while but then which just disappear without you noticing anything.

Hopefully this'll just be the same!
