My favorite pots come with the most-hated lids. They're supposed to be dishwasher safe, but any time I try, they come out of there looking much like this the image below. The problem seems to be the three areas I've circled in red: these let in dirty water + gunk, which then doesn't get rinsed out all the way. So far, I've tried a few times to see if changing the position of these 'channels' relative to the direction of gravity makes any difference, but it doesn't seem so. So each time, I end up unscrewing the knob, cleaning the class, and screwing the knob on (as tightly as possible) again.
My question is: Is there any way (besides hand-washing/washing them separately from anything else in the dishwasher) to prevent this kind of mess from happening? Is there a product I can 'plug' the holes with? Or is this 'normal' and I'm only noticing it on this lid because it's entirely of glass?
