Re: Cleaning the stove
That's called a pilot light that is always on so when you turn the knob, it helps light the burner flame.
If you spray a cleaner directly on the burners, the pilot will go off so later, you can usea regular lighter to light the gas and turn the pilot back on.
And if you don't light it back up, you will smell gas.
So the best thing to do is to clean that area, spray the cleaner on a wet cloth rather than the surface.
