This is how you can remove and prevent fogging

Fogging - the phenomenon

• Fogging - also known as black dust or magic haze - is the black coloring of rooms, walls and furniture in a building.
• The fogging effect mainly occurs in winter after the first heating season. The black coloration also occurs mostly in newly renovated apartments and newly renovated buildings. It is therefore assumed that fogging is caused by the evaporation of plastics, which becomes sticky dust on walls and furniture due to the influence of heat.
• As a result of renovation work, plastics such as paints or varnishes are carried into the interior of a house. If there is now increased heating, plastic particles in the air move from warm areas in the room to the cold areas of a room. However, the causes of the fogging effect are diverse and have not yet been finally clarified.

This is how you prevent the black dust

There are many ways to prevent the fogging effect. First of all, however, it must be pointed out that fogging can hardly be prevented one hundred percent, since heat differences and dust particles exist in every apartment. In addition, the causes of the black dust phenomenon have not yet been finally clarified. To ensure that the black dust develops as little as possible in your home, the following points must be observed:

1. Keep heat differences in your living spaces as low as possible. Avoid localized strong heat development on radiators and cold areas in places, such as on walls. This can be achieved, for example, by less heating all over the room with underfloor heating. Always renovate in spring or in the summer months.

Thorough cleaning of the apartment also includes cleaning the ribbed radiators. …

2. Always renovate in spring or in the summer months.
3. Make sure there is a low level of dust in the air. Avoid anything that increases the amount of dust in your rooms. This includes, for example, the smoke from cigarettes. Therefore, you should refrain from smoking in closed rooms. The development of soot from candles can also intensify the fogging phenomenon. The same applies to oil lamps.
4. Do not use plasticizers in floor coverings or wall coatings. These can be found, for example, in PVC or latex paints.
5. Ventilation Do not keep tilted window. Brief ventilation is better.
6. Insulate cracks in the masonry to avoid thermal bridges.
7. Avoid plastics in your furniture. The effect of magic haze can be considerably impaired by items containing plastic or containing plasticizers. So stay away from synthetic furnishing fabrics, for example.

Fogging - how to remove the black dust

Removing the black dust with commercially available detergents is difficult because the dust can be very sticky and oily. In many cases, therefore, there is only the option of renovating the affected room. Make sure that you do not use latex paints and that you do not carry out the work during the heating periods. In some cases, the sticky dust will go away on its own in the spring.
