De-icer (concentrated spray) - Kbk
I have just bought a De-icer from Halfords (It is a spray, and says concentrated on the label), but does'nt tell me how to dilute it. I am just wondering if I should dilute it or I can directly spray it on the glass with out diluting it.

Any adivce is greatly appreciated.

You don't dilute it. I think the 'concentrated' reference just means that it keeps working down to lower temperatures.

Is it one of these? tinyurl.com/6zhwoe

Yes, spot on. It is on the page you specified. It reads "Halfords Trigger Deicer" in the list. Thanks.

There's no mention on the Halfords' website of having to dilute it. If you click on the image of the bottle it will lead you to a page which gives you the opportunity to ask a question about it. If you did, you'd be the first!

In the past,you could buy diluted or concentrated de-icer.With the diluted the alcohol in it evaporated and left the water in it to re-freeze on the screen-the concentratyed without the water didn't have this problem but the concentrated alcohol was not good for the rubber or paint on the car.

Perhaps that's what wrong with the Holts de-icer I've got. I bought a case of large cans of the stuff from Costco and it's utterly ridiculously worse than useless! It's literally like pouring water on the screen - the frost goes from white to clear but then immediately refreezes leaving an icy mess.

De-icing concentrate ?

I put the engine on and concentrate on my mug of tea and cigarette while the car concentrates on de-icing itself. Symbiosis maybe ?..........

wife bought some teco stuff, made a smeared mess of the windscreen and we ended up changing the wiper blades so back to the halford's variety. jag.

Not really an option with a diesel - mine anyway. It needs a load on it before it produces any appreciable heat through the vents.

I'll endorse Halfords Concentrated, but I also use one of those ceramic serving trays, which I plug in for 8 minutes to pre-heat, then put on top of the dashboard while I have my breakfast. I find that warms the glass enough that when I then spray on the de-icer, the mixture is less likely to re-freeze. If you haven't got one of those, a hot water bottle will do.

I'm amused by the "Night before" de-icer. Ordinary ones are presumably "Morning after", from a qualified dispenser.

So what category does the windscreen cover fit into? ;-)

On a totally unrelated note I was ID'd in Halfords yesterday when buying a spray can of deicer. Clearly, I look dodgy. There was no response to my somewhat sarcastic question of whether it's fine to snort the stuff if over 21...

On reflection should have bought some superglue as well and then opened it outside the shop looking desperate.

Humph,

I had the mother of tellings off on here for doing that (apart from the ciggie bit) from a former Mod. I was singlehandedly murdering Polar Bears and leaving my car wide open to theft by lurking smack users.....(still do it though)

It's OK I do the lurking.......

Bill, I've a case pf the Costco/Holts as well. Usually I squirt and wipe which means the outside stays clear but the chilling effect means it mists up much more inside!

This morning I gave it a liberal squirt and left it instead, thinking the temp might equalise again. It visibly melted the ice but when I went out 5 minutes later it had refrozen as you say.

I keep it in the house so it's warmer, but other than not freezing my hands it doesn't seem to make much difference. I'm going to put it on the Rayburn tonight and get it a bit warmer! (Not on the hotplate I will add). I feel the experiment is doomed to failure though.

For 35 years I have poured warm water (blood heat and no hotter) onto all the external glass, mirrors etc. Got into the car and driven off. All around me neighbours are still scraping away. A 6 pint milk container is ideal, but I spend a little more time on the windscreen to allow the warmth to percolate through. Then my breath does not freeze on the inside of the glass. Get the heaters and demisters on and no problems.
Neighbours who scrape are frightened the glass will crack (never ever happened to me on many different cars) but note I say BLOOD HEAT

I agree with you, clearing frost like this is a Good Thing. Other options are putting a fan heater in the car (bit of a faff, though), and using a cleap car cover, the sort that just covers the windows (this is excellent, but you need somewhere to leave the cover, though, to avoid having a large flappy wet/dirty plastic sheet in the boot or wherever).

I sometimes do this and it is,in the back of an estate,but the car defrosts quickly and is toasty warm when you get in.

That's often fine but the weather we've had recently has been freezing all day. My idiot (for various things, not just this) neighbour left our shared drive and the footpath like an ice-rink after pouring warm water over his car the other day.

I wondered that - the can gets so cold it's painful to hold.

Don't forget it's important to de-ice all the other windows as well as the windscreen.
De-icer (concentrated spray) - Cliff Pope
Don't forget that the point about de-icer is it doesn't really have magic de-icing properties. It works by producing a mixture which has a lower freezing point than that of pure water. Hence if the screen and air temperature is below zero but higher than this new lower freezing point, it will thaw. But in doing so it takes in energy which cools the windscreen (hence the misting or even icing on the inside), and if the surrounding temperature is already below or close to the new freezing point, it will stay frozen or produce a cold slush.

The same with salt on the roads. It can get too cold for salt to work. A well known mixture of sodium and I think calcium chlorides will produce about zero on the Fahrenheit scale.

I have nearly tried all options - Night Before de-icer, Morning After de-icer, covering windscreen with plastic bags/with rags etc.

Now I've reverted back to plain old warm water. Clean, easy, effective, fast and free (almost).

I once heard that de-icer rots the rubber seals around the windows. This still true for modern day cars/de-icer?

What's wrong with just scraping a letterbox with a credit card?
De-icer (concentrated spray) - boxsterboy
I use a scraper myself:

No unecessary chemicals
Bit of exercise to warm me up
No trips to and forth with warm water from the kettle or tap (which needed gas or electricty to warm it up)
Never runs out (unlike a spray can)
Cheap (same one has lasted over 10 years now)
Can take it with me in the car (unlike a kettle of warm water)

Ticks all the boxes for me!

Why bother with that even? Just drive along sounding your horn so that people know to get out of your way. If you start to veer of the road then the kerbs will guide you back onto the road, after all, that's what they are there for.

I've recently started using a windscreen only frost cover. The rubber suckers that stick it to the inside of the screen don't help with positioning the thing so I've bought some thin shock cord, tied it through the hole at one side of the cover and made a hook for the other. With both doors open it's easy to get it placed just right and takes seconds to put on or take off. Seems to work well too.

Coating the rest of the windows in rain repellent helps too.

Steve.
