New reels get opened and a couple drops with the oil here and there seem to loosen up everything nicely for myself. Too lazy nowadays to clean everything out, use to, but this works for me now.
I have seen many reels billed as ice reels become so stiff in the cold weather, that you could hardly turn the handle.
I once asked a rep at the CSI show to put them in the freezer overnight, before I bought any quantity, next morning stiff as hell.Most anglers wont clean and regrease with a quality lubricant like hotsauce, but thats all thats needed.
Gears/sliding parts get grease,bearings get oil.
Anti-reverse roller clutch gets very little oil,if any.Reels that get that sticking feeling when cold/damp usually have some grease that migrated into them.
