Tools & Techniques:
Keep your barbeque clean by cleaning every time you use it. Start it up and use a grill scraper scrape the grill before you start cooking. If you have a porcelain grill, soak and clean it when you do your dishes in your sink. Scraping the porcelain will damage it.
You will from time to time have to clean the burner to keep the burner holes clean. The flame coming from the burner should be blue, if the flame is orange or red you may need to replace or clean the burner. At this time you should also check the gas supply tubes to be sure that there are no obstructions. If you use your barbeque heavily you may want to spray a food safe organic cleaner or degreaser and let it sit for a while and hose the entire barbeque off. And for safety sake on your BBQ, you should only open the propane tank valve half a turn. It will work just as well and if there is ever an emergency, you can shut off the gas in an instant!
