Esiste un modo per ridurre il congelamento del parabrezza interno dell’auto? Ogni mattina presto, la mia macchina si riempie di brina all’interno e devo raschiarla e accendere il riscaldamento del parabrezza per molto tempo. Grazie mille

What kind of settings you have on ventilation?
do you have the inside heater? if you have a parking space with an electric plug on a post, then you should really use one.
otherwise it is just scraping. there are also these “blankets” that you can put on your windshield while parking, those are handy and prevent the window from frosting.
It shouldn’t really frost inside unless the insulation barrier is bad, it’s hard to fix in older cars. What I would recommend is having a bag of cat litter sand in a sock to remove the moisture inside the car. Keep that in and you shouldn’t have this problem.
Get a dehumidifier and then use oven to dry it out when it’s full.

Car interior heater that uses power from the grid. They cost like 20€ in biltema, have one running 1-2h before you start the car, preferably with the engine heater on as well. You can also get air dryer packs that absorb moisture from the air same way as those silica gel packs in product packages and put them on the dashboard when you park, dryer air = less condensation = less frost.
Keep car under a roof.
Silica cat litter in a fabric bag of some sort absorbs moisture from the air. Some people use a sock, I have a stuffed toy that I’ve taken the filling out of and replaced with the cat litter.
You’ve got too much humidity stuck inside, dehumidifier or airing it put properly in a warm dry place should do it.
Clean car interior, dont take snow inside with your shoes. Replace microfilter. Use engine/interior preheaters. (Defa green cable for example).
Frost on the inside means you have moisture in the car.
That can either come from a bad seal or you brought it in (wet clothes, snow on shoes, your breath, etc.)
I use two of these https://kungs.fi/en/product/drying/kungs-desiccant-1-kg/ in my old car.
Bought them at BAUHAUS https://www.bauhaus.fi/kosteudenpoistaja-kungs-1-kg.html
Its like the small silica bags you get when buying electronics but in bigger.
Read the maintenance instructions to keep them working.
Do you clean your shoes before going in car? You have extra textiles in car?
Extra textiles tend to absorb moisture. And your shoes bring lots of snow inside the car if you dont knock them before stepping in. The latter is something finns do automatically 😄
Using air conditioning in the winter helps remove moisture from the car. The air conditioning will not turn on when the temperature is around -15 degrees Celsius. You can also heat up interior and open all windows for a few seconds during a ride. Warm air wirh moisure would be sucked out. But AC works better.
When you are arriving home drive the last couple of hundred meters with windows open and AC or heater off. This reduses the inside temperature of the car and water doesn’t condensate on the windshield. You can also leave the doors open for a minute or two on the parking spot for the same effect.
This works like a charm and your windshield doesn’t freeze from the inside.
In addition, make sure to clean your shoes of snow before getting in the car and check your AC settings that you are not recycling the cabin air.
The key is to prevent moisture to come inside in first place. Clean the shoes, and clothes from snow. Remove snow if that gets into car mats.
Also important is to remove snow from the space between windshield and bonnet. From there moisture gets inside the car.
Also before winter remove dead leaves and pine needles under the bonnet.
Drive longer distances, use defrost plus floor setting and A/C. When too hot, open windows a little. Hot air absorbs a lot of moisture and open window will release it outside while keeping your driving comfortable.
Do not vape inside as it form as frost binding film on windows.
Wipe the windows inside with washer fluid as it degreases it.
Gather all the thrash out from the car as it binds moisture and release it in the air when the car warms up.
Buy some crystal cat litter, put it in thin sock or something like that as it absorbs moisture yet do not release it back.
Last kilometer before parking overnight put heating to coldest possible and open windows wide open to make the indoor air cold as dew point is where warm air meets cold surface (windows).
Clean your shoes from snow when entering the car. If you bring snow on the floor it is the same as pouring water in the car. The humidity condenses on windows and freezes on the inside.
A dehumidifier helps also as others have suggested.
Buy Ford? They have full frontglass defrosting – it’s really awesome.
Thanks so much guys.
Clean it with window cleaning detergent and never touch it again. Also don’t smoke and definitely don’t vape in the car.
Others said to use cat litter box silica gel in a sock, but rather use stockings or something long and cover the whole area. Also pay attention to not cram it between the windshield and panels as temperature changes and it could crack the window.
When the interior is warm, open the windows a little so the humid air can escape. (I’m not sure about effectiveness of this, while still i’m doing it.)
Of course you can use an interior heater from grid or fuel heater like webasto or something. But that’s not what you asked.
That is 100% sure to happen if you only drive short trips. Most probably you have brought the moisture in your self within your clothes and shoes.
Silica gel, cabin heater if you have electricity available for it. Will help.
Taking a long road tip would also dry the car.
Yea, my kids completely disagree with cleaning shoes of snow before entering the car 😅
You have gotten many good answers, but my two cents nevertheless:
You probably have brought lots of snow into the car with your shoes and clothes, that melts onto the car mats and the seats and evaporates into the cabin air when the cabin is warm, so the frost is excess moisture from the cabin air that is condensating and freezing on the inside of the windows when the car is cold, as cold air is unable to contain as much moisture as warm air can.
To mitigate, you’ll have to A) prevent new moisture from entering the cabin, and B) get rid of existing moisture out from the cabin.
For A), you’ll have to better shake off your shoes and clothes from snow and slush before entering the car.
For B), you’ll have to shake off your car mats into the outside from excess snow, ice and meltwater, run and drive the car with high heat and high ventilation and with the ventilation directed towards the windows and the feet (to dry off the car mats), with the inside air circulation disabled (otherwise the moist air will just keep circulating inside and not exit), and with AC enabled (since it helps with removing moisture from the ventilated air).
If you can run the ac with the heat on, it will reduce the interiors humidity.
There can be many possible causes, but these are the advice which helped me:
Keep the doors of your car open for a couple of minutes before leaving your car for the night, so there will be no warm air inside.
Check your cabin air filter. In my case there were ice particles, the situation with the windshield got improved quite a lot after I removed them.
One trick is to open your windows for a while before parking so most of the humidity gets out. This is especially effective when it is very cold outside.
Acutely, some window scrapers have a perpendicular squeegee edge that works nice for removing condensation, whether it’s fog or frost. Ideally, have something underneath to catch the water/frost as it comes off the glass.
