when corrosion and electrochemical reactions are an issue, eliminate them by using plastic or glass.
Forget the towel, anything solid to cover up the flame will do the trick. If all you have is a towel, use it wet. Backing soda, salt, towels (wet or dry) lids- they all do the same thing which is to smoother out the fire. Fires require at least 21% oxygen to burn so reduce that down and the fire dies out. The reason behind not using water, Im sure you've mixed water and oil in a pot or measuring cup well notice how the water is heavier and sinks while the oil floats on top, thus water will not put out an oil fire. Therefore you need a dry extinguisher which has lighter chemicals than water to put out the fire. Foam does the same thing. Wet extinguishers use primarily water.
