Short answer: Dishwashers are savage.
Anodized aluminum is incredibly durable — heat-resistant, corrosion-resistant, and built to last — but dishwashers aren’t gentle. The high heat, aggressive water jets, and harsh alkaline detergents can dull or discolor the finish over time. That sleek, matte surface? It’ll come out cloudy, scratched, or spotty if you toss it in with your plates.
But here’s the kicker: while a dishwasher can ruin the finish, a lighter can’t.
That’s right — anodized aluminum holds up to flame just fine. It’s one of the reasons it’s such a solid choice for smoking gear. The anodized layer isn’t a coating — it’s a transformation of the surface itself. It won’t burn off, it doesn’t leach, and it doesn’t flake. So while you should definitely hand wash it to keep it looking pristine, you can use with full confidence.
Dishwashers destroy beauty. Flames don’t.
