Hey Bob, HELP!! I am a Long Term Care Ombudsman and work with senior citizens. An elderly lady in a senior high rise has a problem with black soot rising above the electric basebord and going to the ceiling. This happens every year when she turns up the heat. An electrician said it is from burning a candle--is this possible?? This is a small apartment and she is a nonsmoker. She is very concerned. Do you have any ideas? Thank you so very much.
