Love these bags! They're super durable and I love that they can go in the dishwasher. I've been recommending these to friends and family – they're worth the investment :) I haven't had them hold smell or stain yet, but that's because I've only had them for about a week! And I mostly use them to store lettuce for freshness. So hopefully when that happens, they'll be easy to clean! Love that Stasher gives a lot of cleaning/stain removal tips included with the bags. Thanks, Stasher!
