I got the new clean sweeper skin, and I found a clean sweeper in my world via a living tree. While the clean sweeper was in my hand slot, I tried to sweep the item in my hand slot to apply the new skin. Instead, it swept my character's beard (Wilson). I thought only clicking on your character could sweep their beard, not the hand slot?
Regardless, the only way to get the new skin as of right now is to craft it at a magic station, which seems counterproductive as I already got lucky enough to find one in my world. I'd just have two brooms for no reason.
1. Get a clean sweeper.
2. Equip it in your hand slot.
3. Sweep it.
