To deal with winter window condensation, reduce indoor humidity (use exhaust fans, don't dry clothes indoors), increase ventilation (open windows briefly, use ceiling fans), and improve window insulation (weatherstripping, window film) to keep glass surfaces warmer, wiping moisture away to prevent mold and damage. Using a dehumidifier is also very effective at removing excess moisture from the air.
Try and avoid it getting too humid inside a room so open windows and increase ventilation when cooking or showering. Avoid drying clothes inside too as this increases moisture build up. You could also try and not use curtains or blinds that might block moisture close to the window.
Should You Wipe Condensation Off Windows? Yes, wipe off any condensation on your windows with a soft microfibre cloth. It's one of the first things you should do. Not only does it protect your windows and sills, but it also helps maintain healthier indoor air quality by stopping mould from growing.

Short answer: Yes--plastic film over windows reduces condensation by improving insulation and lowering the window's inner surface temperature, but effectiveness depends on installation, window condition, and indoor humidity control.
Salt is hygroscopic, meaning it naturally attracts and absorbs moisture from the air. When placed next to a cold window pane, it can help reduce the amount of water that collects overnight — particularly in small rooms or on single-glazed windows.
Condensation happens because rooms get too cold, they fluctuate between cold and hot, and there is excessive moisture from cooking, washing and expiration. The biggest causes are showering, drying clothes on radiators and boiling pans. Underlying issues of damp can also be a persistent problem.
Yes, you should wipe condensation off your windows. In fact, if this happens regularly, it's a good idea to get into the habit of removing it every single day, recommends Stephen Hankinson, Heating Expert at Electric Radiators Direct.
Myth 6: Washing windows with dish soap will permanently stop condensation. Applying dish soap to windows can provide a temporary solution by creating a film that prevents water droplets from forming; however, it's not a permanent fix. Over time, the soap film will wear away, and the condensation may return.
Does condensation on windows mean poor insulation? Not necessarily. Interior condensation often indicates high indoor humidity levels rather than poor insulation.
THE TEMPERATURE OF YOUR HOME
Cold air is more likely to deposit droplets of condensation around your home. Air is like a sponge, the warmer it is, and the more moisture it will hold. Heating one room to a high level and leaving other rooms cold makes condensation worse in unheated rooms.
The Snake Plant is perfect for a bedroom as it absorbs water vapour at night, helping to tackle nighttime condensation on windows. Also, the plant will remove carbon dioxide from the air during the night and produce oxygen which is needed for a good night of sleep.
Signs of excessive HVAC condensation
Over time, condensation can lead to mould growth. It appears as pinpoint black spots, usually on the side surface of external walls, in corners and in poorly ventilated spaces, such as behind cupboards and wardrobes.
Don't keep it running all of the time
One of the questions that I get asked the most is how long a dehumidifier should be left running for. Marc Duckworth, the Product Manager at Philips, says, "humidity levels can be on the rise in the winter.
Try to keep your home suitably heated. It usually helps to have a low background temperature of at least 15 degrees in all rooms. By doing this you are less likely to have condensation dampness as the warm air holds more moisture than cold.

Excessive window condensation and frost can lead to problems
Accumulated moisture on windows creates an ideal environment for mold and mildew growth. Breathing in mold and mildew spores poses health risks, especially for those with allergies or respiratory issues.
Condensation on the inside of your windows
It's quite common to see levels of condensation on your windows, ESPECIALLY IN THE MORNING! This happens when the temperature outside drops overnight. It clears as the temperature warms up as the day goes on.
Pour cleaning solution (water mixed with liquid dishwashing detergent) into a plastic spray bottle, then spray the interior surfaces of the window. 13. Immediately after spraying, clean the glass with a terrycloth rag, followed by a quick wipe down with the micro-fiber towel.
In most cases, internal condensation issues occur because of too much humidity in the room or little to no air circulation. Low internal room temperatures can also create cold surfaces (particularly on windows and exterior walls) which allows warm air to condense onto them easily.
You may only notice this a few times a year. When you do, rest assured, it's the result of conditions outside — not a sign your windows are failing. In fact, condensation on the outside of the window is a sign of energy efficiency. It means the outside pane of glass is thoroughly insulated from the heat indoors.
Where a dehumidifier can remove excess humidity it can't lower the room's temperature, an air conditioner will reduce the humidity AND lower the temperature significantly to reduce condensation and prevent damp from forming. Damp homes are not only cold and uncomfortable, but they can also be bad for your health.
