Being on summer break (I'm a high school teacher), I took advantage of some decent weather and cleaned out my 2 Star. I removed the hood and scraped all of the built up char from inside the hood. I find that if I don't remove it, I sometimes get black flakes of crud on my food. I also vacuumed out the interior and cleaned the outside surfaces as well as scrubbed down the Flame Zone parts. The grates also go a scrubbing. Although it doesn't look brand new, it looks pretty good for a 2 year old, heavily used MAK.
