How do you fix thermal tracking ghosting?
If thermal tracking occurs in your home, you can try scrubbing the walls and ceiling with a mild cleaner to remove the stain. If that doesn’t work, you may need to sand and repaint the surfaces. But that’s only half the job. You also want to make sure this “ghost” doesn’t reappear in the future.
Can you paint over thermal tracking?
As long as the insulation has not been wet (and at risk of mold contamination) surface staining from dust deposition by air movement across the insulation won’t impact its effectiveness. Watch out: if you try simply painting over dark thermal tracking stains the black stains may bleed through your new paint job.
What is the cause of ghosting?
Monitor ghosting occurs when an image artifact appears as a trail of pixels behind a moving object, almost like a motion blur.

What is thermal bridging in a house?
A thermal bridge, also called a cold bridge, is an area of a building construction which has a significantly higher heat transfer than the surrounding materials.
What causes ghosting on a ceiling?
Ghosting is the result of a slow build-up of soot, dust, dirt, and other particles that have attached to objects such as studs, joists, walls, ceilings, rafters, and even sheetrock screws.

In fact, black dust may be due to deteriorating duct liner materials in your heater or air conditioner and in some cases cold air returns. It may alternatively be due to soot produced from candles.
How does thermal bridging work?
Thermal bridging is the movement of heat across an object that is more conductive than the materials around it. The conductive material creates a path of least resistance for heat. Thermal bridging can be a major source of energy loss in homes and buildings, leading to higher utility bills.
How do I get dark spots off my ceiling?
