It isn't a discipline problem. It's a logistics problem, and it's built into how aligners work:
The napkin is where retainers go to die.
Ask any orthodontist what the number-one way to lose a tray is, and you'll get the same answer: wrapped in a napkin, cleared with the plates, gone. A replacement typically runs a few hundred dollars — plus the days your teeth spend drifting while you wait for the new one.
The film builds faster than you think.
Trays that sit unrinsed develop a cloudy film within hours — saliva and soft plaque setting onto warm, damp plastic. That's the haze, the smell, and the trays you're quietly embarrassed to take out at dinner.
Your routine is scattered across three rooms.
The soaking glass is in the kitchen. The brush is at the bathroom sink. The hook is in a drawer somewhere, and the only mirror is bolted to a wall. Every missing piece is one more reason tonight's soak doesn't happen.
Fishing trays out of solution defeats the point.
You soak them to get them clean — then plunge your fingers into the used solution to get them back. Or you tip the glass over the sink and watch a tray you paid hundreds for slide toward the drain.
It isn't that you're careless with your trays.
It's that nobody ever gave you a place for them.
