After unloading developed film I put the reels and other tank components in a basin with a strong but dilute detergent (not the "kind to your hands" sort of thing) then rinse and dry thoroughly. I don't have a problem usually. If I'm having trouble and get flustered and hot and bothered and start to sweat a bit (depends on the weather obviously) it gets worse.
I find it helps a lot to straighten the start part of the film and I clip the corners a bit to help ease the film into and around the reel.
Using a detergent, rather than a wetting agent such as PhotoFlo, is a bad idea. Detergents even though it has been diluted has perfumes and additive that are not good for film. There are many threads on APUG about this subject. Do not use any detergents, stick with wetting agents.
Also, I don't usually used heated dry when I do dishes, but my wife does. I was afraid I would forget to check the setting and figured heated dry was not good for the reels, etc. So now, I periodically soak them in a solution of clothes detergent and then rinse thoroughly. Once dry, I just tap the reels to insure the steel balls are moving freely.
