Defogging front window

restive

Four months ago I bought a second hand golf. Car is great but I am having an issue defogging the inside of the front window. This only occurs on certain mornings when it is heavily fogged up. I had the garage take a look at it and they said the airflow was working properly. It can take roughly 20 minutes to defog. Any ideas? I have a cloth for back up!

Excessive moisture in the car.

Put a dehumidifier in it for a week. Small ones from Aldi. Should improve it.
Make sure your ac is also set to take air in from outside and not just circulating

Seals are gone In some part of the doors j would expect ,.make sure to leave the vents open all the time , especially overnight.

Try leaving a few of those large moisture bags in the car if you have some.as they will soak up.the humid air

Air conditioning should help if the car has it.

Crack open the front two windows (just an inch) when defogging the windscreen. The moisture needs to escape and it will take longer with the windows closed.

If the car has air conditioning make sure you turn that on and make sure you it's working properly (a/c needs to be run for at least 30 minutes every month to keep it in good working order).

Assuming you're using the a/c and the system is in good working order then unless there's been snow or the temperatures are below freezing, the windscreen should be clear in no more than 5 minutes and certainly the bottom quarter should start to clear within 30 seconds.

If this doesn't happen then you must have leaky seals (or a leak of some description) somewhere. A faulty pollen filter will also prevent the a/c from doing its job and as a result it will take the windscreen a lot longer to demist.

When was the pollen filter last changed? They can clog and block airflow which makes it hard to clear the screen.
Also clean the inside of the screen so it's spotless, it won't fog up as quick once it's kept clean.

After you've used your cloth, take it out of the car and replace with a dry one. Go for a drive with the windows down on a dry day. Give any removable floor mats an airing

I have not yet serviced the car as I have it four months. Garage did not see any issue though. I'll try some of the recommendations suggested. Thanks for the replies.

Was slagging a co worker with a Golf the other morning for driving to work with their car frozen, they only live a few minutes away so car doesn't warm up. He said that he had the keys in his pocket and the 4 windows opened on a night it pissed down, car has water freezing inside the windscreen. I told him to get a dehumidifier and stick it in the car with the heating on, obviously making sure that it can't be stolen. Maybe your car had a similar thing happen, can you feel damp on the carpets or under them.
