Addendum

I feel compelled to add, once in every few loads some of my glasses aren't as sparkly. I read that you can just fill the rinse dispenser with white vinegar to fix this. I personally can't find the rinse dispenser on my dishwasher, so I decided one or two slightly foggy glasses were workable. But I may get out the manual in future...

(This is a follow up to my last post.)
