My roller door squeaks when going up (but not down). A bit of googling said clean the guides with Mr Sheen which I did and it still sqeaks. I am a bit hesitant to go spray lubricant every where as I don't want the guides to get greasy and look shitty.
Here is some pics (sorry my ms paint is shit)

EDIT - I was running it up and down to try and work out where the squeaking was coming from and it stopped, so I guess the Mr Sheen worked.
Well lubed interfaces usually do look "shitty" - decide if you want squeaks or squeaky clean.
