Ionic air purifiers. They charge or magnetize the particles and then they cling to everything. Remove a picture from the wall - is the ghosting around the outside? Remove a metal decorative piece - if the particles are magnetized the ghosting will be the opposite - it will be in the same design as the item.
Are you sure it is not mold? That could be a health risk. If you heating with an oil fired furnace it might be cracked and allowing exhaust in your home. You might need to have this checked out proffessionally since the by product of this exhaust is carbon monoxide.
Soot is produced in incomplete combustion of hydrocarbons. Soot is black and leaves marks. It also causes health problems if in contact or inhaled!
because the soot from the candle rises and sticks to the ceiling which is how they get dirty
A black ceiling fan is likely to show the same amount of dust, unless the dust is dark in color. For instance, it could be mold spores or soot particles from candles. In this case a black fan will be less likely to show the particles.
To stop the black residue from a baseboard heater, the wall around and near the heater should be cleaned as there are dust particles attached to the wall. This is called ghosting which fine particles of soot attach to the wall that is cooler than the temperature.
The formation of black soot indicates that the combustion is not receiving enough oxygen and is incomplete. Black soot is made from mainly carbon.
Soot is a noun. It is the black residue left behind by burning some substances.
You still have some soot on the very tip of your nose.
Soot will accumulate over time and may form more quickly if the gas contains impurities.
Soot is the black carbon based substance leftover from incomplete combustion. It creates fine particles that tend to stick to nearby surfaces.
aerosols and soot from air polution
use a Mr. Clean magic eraser. that will get anything off.
If you think to black soot this is formed from tiny carbon particles.
a mixture of pollutants such as carbon particulates (CO) and carbon monoxide. But mainly the carbon particulates other wise known as soot.
black soot and ashes
The glow of the luminous flame is due to incandescent carbon particles. When these particles leave the flame, they cool and become black soot.
Examples could be:As black as nightAs black as darknessAs black as a catAs black as sootAs black as coal
