 and clean them out, rinse them out, and then put them back together. And I will warn you, it's a bit of a Rubik's Cube puzzle to take those things apart and get them back in the right shape. So when I take them apart, I carefully set them on the countertop, and I remove the layers one at a time until I get to the screen and put them back in the same order, so it'll just be a little bit easier. It's been a few times where I've had to futz with it for a bit to figure out how to get it back together.
