Condensation on windows is a phenomenon that must and can be fought. Industry has not yet provided ways to eliminate moisture on glass, except by installing an additional heater.
But there are folk tips that help overcome this problem.
Firstly, you can install an additional heater for the winter, but not everyone can afford it.
Secondly, you need to check the operation of the ventilation.
Thirdly, you need to ventilate the room as often as possible. General recommendations: 5 times a day for 5 minutes or at least once a day for 10 minutes.
Fourthly, you can stick a special film on the glass for the winter, which also acts as insulation.
Fifthly, you need to remove indoor plants from the windows. If these are flowers with large leaves and there are many of them, then a special microclimate with high humidity can form on the windowsill.
In this case, no life hacks will help.
And finally, housewives say that if you keep ordinary table salt on the windowsills, it will absorb excess moisture and prevent drops from appearing on the glass in the apartment.
