For the last several months, the little holes on my gas cooktop get plugged up with gray ash. Sometimes the flame burns yellow at the tips instead of blue. I poke the plugged little holes with a toothpick. That helps for about a week. Now my pots and pans are getting this black carbon deposit on the bottom, and the holes keep getting plugged.
What is happening? The burners are sealed (I have a Maytag stove), so I don't know what I'm supposed to do to clean the darn thing.
Advice is appreciated!
