Query: Nice machine, difficult to clean

I don't drink coffee, but my husband does. He says it makes nice fresh coffee. We use whole beans and grind them in the mill. I read the other reviews before purchasing, so I was aware of the delicate nature of the lid and the screen. We've also tried the programmable feature, and that was nice that I didn't have to get up to make coffee at 4 in the morning!My issue is with cleaning the screen. I don't want to scrub too hard for fear of tearing the screen, but I can't get it clean. Maybe there will always be residue, but even after doing vinegar cleanings, the residue remains.
