Well, I have been using my Char-griller duo for two years - going on three. This year I decided I would clean out both the smoker and the grill sides. When I took off the cover I noticed some small critter has tried to make a home in the grease trap at the bottom (acorns, droppings found). This furthered my desire to clean everything out - no signs of anything coming in contact with the actual grill grates, but better safe than sorry. I used warm water with dish soap in a 5 gallon bucket. On the smoker side I had to use the back of the grill brush (scraper) to remove large chunks of old drippings. I didn't get everything out, so some of that old 'seasoning' was still on everything.
Once clean, I let it dry out until Saturday morning. Using veggie oil, I wiped everything down. I then fired up the grill side and the smoker - time to get cookin'!
One the menu - a 4-5lb Brisket and 5 chicken breast. I covered the brisket in my current favorite rub - 3 beer http://weingeorgia.com/ - the night before and it was ready to go. The chicken breast I cleaned up, and split down the middle. I stuff some with mozzarella and some with sharp cheddar. All of the chicken breast were then wrapped in bacon (some more than others).
Take about good!!!! I cooked to temp using my digital thermo and the results were amazing. The chicken stayed on the smoker for about 4-5 hours and the brisket was on for ~6 hrs. The wind and cool air made keeping this smoker consistent an issue, but with a little attention everything turn out perfect.
Here are some pics!
