Do such things exist?

Off to get tyres fitted but will have a search when I get back. Just wondered if anyone knew or was using them.

I guess I'll have a trawl through Canada section of the site. If anyone knows, they must...



(Only heated enough to stop 'em freezing btw. Don't intend spraying boiling water at the screen.)

This would be a great addition to anyone's S. No matter how much antifreeze is in my washer bottle, it still takes 30 minutes to de-ice

Yes most mid-range cars have them (sometimes options on merc's etc), and you can buy a thing called 'heatshot' but expensive at £200. Or use heavily concentrated windscreen washer fluid.

Plenty exist. You could probably retro fit them from another marque (or even another Honda) and wire them to a switched 12v feed.

Only thing I'd say - no point in having heated washer jets if the water in the bottle has frozen, and the jets certainly aren't hot enough to heat the water as it passes through so no good for de-icing. In fact, I'm not entirely sure what the point in them is as a stand alone.

Some cars do have heated washer bottles as well.

There must be a small element you can buy to drop in...

Time for Mr Google to help.

It's not to defrost the windscreen but mine were frozen for my whole journey home from work. I'm using pre-mix washer fluid that's supposed to be good down to -5c but it's no use.

I guess using a higher concentration rather than pre-mix may help.

Or as said above, heated jets and buy longer tubes from bottle to jets and re-route past something warm and hope convection does the rest.

Some do heat the nozzles, lines and bottle.

Rig up a heat exchanger, though you'd need a 12v source to fully effective. Again look at heatshot.

No point at all, it's just a bad screen wash mix.

As you can see here :

Neat Isopropanol won't freeze until the temperature is -73°C which has never happened in the UK ever.
A bottle of neat isopropanol will boil out of your screen wash bottle at 12°C though so it's no good for the summer.

A 10% mix is good up to 41°C though so if you stay on top of the mixture concentration you will never have a problem in the UK.


This is all down to the "dumbing down" of motorists, when I learned to drive you had to mix up your own screen wash. Now you buy it ready mixed and if it freezes then tough crap.

Buy it here:

Never have this problem again...

Mistral also sell isoprporinol on eBay (but they have shut down for Christmas/new year). It won't harm your paintwork, not sure about waxes, but I'm not worried till spring.
And you can use it for loads of other things.

Cool, ta.

I've only used water in the past in summer and this pre-mix stuff served me well for the last few winters. I'll give that a go.


I just wanted to fiddle with something to be honest lol.

I add a little meths to the washer bottle and use a strong mix of screenwash in the tank this helps, it's not the ambient temp that causes the jets to freeze but a combination of that and the windchill caused by the moving car through the cold air.
