Let me tell you a short story. I have an Uncle who is slightly crazy(been in and out of an institution several times) and he got the great idea of heating his house with candles. We both live in the north east US it tends to get cold here in winter, well the summer before the test he began buying candles by the gross. Half way through the winter he had to replace his computer, his audio reciever and his wireless doorbell among other little electornic devices. He discovered it is cheaper to buy heating oil. Bottom line soot=short elctronic life.
