  1. soot seems to be my problem. I have only electric heat, baseboard and storage units, but my wife burns many candles. The problem seems to me is magnified by my use of room humidifiers, is that posible? Would air pruifiers help? What works good to clean with? The soot realy shows up at nails on outside walls, and at the corners of outside walls where the trusses are.

    • Hello Chuck,
      If soot deposits only appear in the spots you’ve described, it sounds like you have a house insulation problem. Even without burning candles, those areas would most likely become darker just from dust particles sticking to colder surfaces. Of course, soot from the burning candle flame accelerates “darkening” / appearance of ghost marks process. By using the humidifier, colder spots on walls will have slightly higher moisture level and soot / dust will more likely stick to that spot. Air purifying equipment should help to reduce amount of soot particles in the air, but not all of the purifiers are alike, so do some research before you invest several hundreds of $$$ in it. As for the clean-up process, depending on contamination, complete stain removal might not be possible. This 3 step method sounds promising – Soot sponge .
