I’ve got a few pairs of cedar shoe trees that are over a decade old. Do these things ever lose their effectiveness at absorbing moisture and/or de-stinkifying shoes?
They don’t smell of cedar as strongly as they did when brand new, but I’m not sure if that really has anything to do with it.
Yep, they can dry out and lose enough essential oils to reduce their effectiveness over time. But as **beowulff **says, they’re quickly rejuvenated with a light sanding.
