Front windscreen de-fog

[Kate1304]

Just a curiosity, does anyone else’s front windscreen take an absolute age to defrost but the back windscreen is fairly quick?

Thanks

The only heat available to defrost the front screen comes from the engine coolant, so doesn't work until the engine starts to warm up. You need to use "traditional" methods if you want to drive away straight away. The rear defrost is electric.

Jug full of lukewarm water on the windscreen warms it through and prevents it fogging up when you get in it to drive first thing.

2 jugs this morning because it was absolutely freezing!

I prefer to use a scraper on the front screen while the engine is warming up, however...DO NOT be tempted to use hot water you could crack the screen.

Cupra app has it's uses - turn on air con about 5-10 minutes before I need to leave home. Car is defrosted and nice and toasty inside

Yep lukewarm not hot water.

Been using it for years never had an issue, very quick to deice and it preventing windscreen fog from forming on the inside while the car is getting up to temp is an additional bonus.

Is that feature only for PHEVs/EVs though?
