My garage door is a Henderson Canopy door with nylon rollers running in a vertical tracck.
I have just given the track a good clean and I am wondering is it best to lubricate the track - which could cause the rollers to merely slide - or keep the track dry and clean to encourage the rollers to rotate as wheels. (however if they don't they will get flats on them.)
I have a similar situation with kitchen drawer units - the rollers now have flats on them and they act as sliders rather than rollers.
