Terra-cotta space heater for a small room. Several ways to provide heat for an entire room. Going to keep a supply of pots and candles on hand to warm each room just in case the power goes out this winter!
Take a microwave safe bowl and fill it with water. Add a dash of vinegar. Set it in inside and turn the microwave on for 5 minutes. The water will turn to steam and the steam will soften up all the gunk. The vinegar helps to absorb the smells.
