This was eye opening, more than a little disgusting, and not as huge a success as I had hoped. I still would recommend everyone do this, because thinking about what is in your dishwasher will disgust you anyway!
Step one is to take out the bottom shelf of your dishwasher. This is easy, just role it out and lift it up. However, don’t let your kids realize it rolls, that just leads to a whole other issue! They never want to give it back. Then, there is the matter of taking out the twirl-y thing on the bottom. There should be a lever type thing at the bottom and you pop it, and it’ll come out.
