Hey! So, cleaning the Bentgo Fresh lunch box is pretty straightforward. The manufacturer's description mentions that it's safe to put in the top rack of the dishwasher, which is super handy if you're busy.
But here's a tip from our research: while you can throw the whole thing in the dishwasher, some folks prefer to hand wash the outer shell. They only put the tray insert in the dishwasher. This way, it seems to help keep the box's sealing parts in better shape, as they might wear out if exposed to too much dishwasher action.
And good news, the materials are BPA-Free and food-grade safe, so no worries there. Still, a few people mentioned that if you regularly put the lid and hinges through high-heat dishwasher cycles, they might not last as long. So maybe try handwashing those parts to be on the safe side.
The tray's usually fine to go in the dishwasher, just make sure to dry it well afterwards. Its ridges can trap water, which could lead to issues like mold if not dried properly.
In a nutshell, while you can use the dishwasher, mixing in some handwashing might be a great way to keep your Bentgo lunch box looking and functioning well for longer!
