Something that you can do which speeds up the defrosting process (safely) is to place a hot water bottle on the dashboard (not touching the windscreen), also, when running the engine from cold, don't be tempted to turn the heater to max heat until the gauge shows the engine's temp increasing (otherwise, you are drawing any heat from the engine, blowing cold air onto the windscreen, and delaying the engine from reaching a warm temp).

An ice scraper will also assist with the side windows & upper regions of the windscreen.

Thanks for that Paul, i'll try to remember the hot water bottle

  1. Before getting into the car (if its been frosty) give the wipers a gentle pull off the windscreen just to ensure that they aren't frozen on. Saves risking the wiper blades and/or electrical failure on the wiper motor side.
  2. NEVER be tempted to pour warm water over a frozen windscreen - I've seen someone do that, and they looked a right prat trying to claim it was a stonechip...
  3. Always ensure that your windows are clear before heading off - the police won't appreciate your Time Management skills when they pull you over.
  4. Lastly, your battery is your best friend, get your engine running before using your heated seats/rear window, etc.
The way I see it, following the above checklist, may make you a little later for work, but it saves a lot of time/money in the end.

I've never had a problem with de-icer damaging the paintwork. I think some people have been daft enough to use anti-freeze instead, with disasterous results. That stuff belongs in your radiator and nowhere else

I cleared the windscreen with de-icer this morning while I left the engine ticking over. The temperature gauge hadn't started to climb the scale, but then it doesn't until I get on the motorway on mornings like this (damn the thermal efficiency of the diesel engine!) I sat in the car and revved it a bit (I know it uses more fuel, but I feel it's kinder to warm it up quickly than to let it idle up to temperature) and as the screen wasn't showing any signs of fogging up again, I started to drive.

Within 30 seconds of hitting the main road, I couldn't see a damned thing. The whole windscreen had frosted over again. I'm guessing that the sub-zero temperatures, combined with the wind chill factor of the car moving through the air makes even the de-icer freeze on the windscreen.

So if I have to do it again in the morning, I'll be removing all moisture (including de-icer) with a squeegee to see if that helps. Though using the wipers didn't, so I'm not sure what the answer is.

It's Renault's fault really. If quick clear windscreens had been optional on the diesels when I'd ordered mine, then I'd have had one. But for some reason, they only did them on the petrol engined models at the time.

Same problem for me, except I don't live by a river, I have one running arround in my rear footwell, well the remnants of one, it just hasn't dried out yet.

I always find it easiest to do the old thing and chuck an old sheet over the front and rear screens. I do this mainly due to the fact that I get up about 04:30 and need to be at work by 05:00 so never have enough time to muck arround with scrapers etc. Also it normally keeps the inside of the screen pretty clear due to the warth eminating through from the sheet outside which means I don't have to run the car outside my neighbours house for ten minutes, see it's a clackity ol' deisel and I wouldn't think they'd appreciate it at that time of the morning.

Just a note on those eediots that use hot water on their screens. I'm a postie and I must have seen 15+ people doing exactly that this morning, do they not have any common sense?
