Of course, to boost sales, candle-makers find that they have to offer products with an intense scent. This is accomplished by adding scented oils into their wax mixture. This often causes the candle to burn improperly and increase the production of soot. It looks like soot, which is a carbon residue produced by burning, can create a large, expensive problem. Since soot is particulate matter that can be carried through the air, it can seriously stain walls, carpets, and personal property.
Studies show that electronic and plastic components are also vulnerable to soot damage.
Unfortunately, soot produced by improperly burning candles bonds very strongly, making it difficult to impossible to clean. Further, soot may contaminate a home's heating system, including ductwork. The soot can then be spread throughout a home, creating widespread damage that is difficult to repair. Property stained by soot may have to be cleaned by professionals and, often, the property has to be replaced. You may have assumed that the only materials found in candles were the wick and some type of wax.
