I use hot pure water for everything and chemicals very occasionally....windows,f/s/g jobs/conny roofs and solar panels....

Each to their own but I know what I prefer.....

Enjoy the match lads!👍😄

I would be a little peeved if I had splashed out 5k for an all singing all dancing hot  system, only to find I then have to splash out even more money on some poxy chemicals  to shift some stubborn muck!
Isn’t that what the scalding hot water is meant to do?

Hot will remove some items quicker - it depends on the stain - some marks may require chemicals as well - for example tiger stripes on upvc

It comes down to whether you feel 5 grand plus running costs are worth the small gain made

It’s like hypo - I have a guy that thinks this will remove everything - then I get a call saying he can’t clean the effervescence off a wall - what did you use - hypo! - no you need an acid cleaner
It’s simple really we need an assortment of techniques to cover the variety of problems and furthermore different people find different ways to solve a problem

When you clean with hot water you will only have very few spots of water left on the glass to dry off,when you clean with cold in a lot of cases the windows are covered in spots of water that is yet to dry especially on hydrophobic glass and this is annoying to a lot of customers I have that have had a cold cleaner prior to me,
It’s horses for courses it’s no different to an electric hose reel why would you want to manually reel in all day,why would you want to use a heavier pole the same can be said for hot water why would you want to scrub and scrub birds 🦅 mess or have to spray a detergent on your brush head.
Hot water deep cleans PVC windows or similar  the same for lead on a window each time you go back even if it’s a quarterly clean it’s way easier.

hmmm - I like this "buzz" word deep cleaning

so Nigel what does it mean ?

I’m not sure if you’d know what going deep means Darren but a real deep clean you know when you clear everything out of every crevice lol.

 IMO its not just that hot pure water removes the insect spots,baked on bird muck on frames and glass,sticky pollen,grass cuttings,leaves,snail trails easier.....also hot water gives a better flow to your brush,windows rinse easier and dry much quicker and much more manageable hoses all year round.....

you boys carry on with cold water if your happy with that....i really dont give a toss anymore.....

There's no real need to use purified water on fascia's and so on, if possible use the customers tap water , that extra pressure makes all the difference.

Not if the customers tap water is chalky...where I work the tap water is mixed with bore hole water and makes a right mess of the glass so pure only on plastics too....

Daz why on Earth would normal tap water make any difference to gutters or facias? I live in the second hardest water area in the whole country, and can tell you categorically it makes absolutely no difference. Why would it? It’s not a see through object. It’s plastic facias and gutters.

Of course you use pure for windows, isn’t that completely obvious? We’re windowscleaners, if we aren’t using pure for windows then there’s a problem between ones ears.

the chalky deposits in the tap water make a mess of the glass when cleaning f/s/g jobs plus i like to use hot water on plastics too....it saves time fannying around plugging into customers outside taps with a separate length of hose....this means i can clean the windows at the same time without swapping water sources.....

i keep it simple these days...hot pure water for any cleaning i do whether its windows,plastics,conny roofs or solar panels....

Interesting Chris. Most who've gone over to hot have a dogged refusal to accept it was not worth the investment.
I've always thought this was down to it either being because it does a considerably better job or having to convince themselves it does because of the money they've invested. What hot system have you been using ? and what is your chosen chemical ?
I'm a cold user but may have had an interest in going hot at some point.

Mines an insulated immersion system from toolcraft. Before NHW says its an immersion so its not hot enough, I have it set to 70c and the water is so hot coming from the brush that I can't even hold my hand there for a second. Temp from brush 2 days ago was 59c.
It was around £1500 to purchase the system and my electric bill is about £60 more a month to use it. So around £12.50 a week. Not much but when you consider that brushes only last a few weeks now before there mangled as well as I cracked a window a while back costing about £150,  it works out quite expensive.
If the benefits were truly great then I would say its worth the cost but as I said in my original post, cold and chemicals easily out perform it.
For chemicals I get them from a local supplier, the stuff is called Merlin extra heavy duty cleaner/degrease. Its the biz.

the best brushes for hot water cleaning are the stiff supreme brushes,they dont go out of shape and last 3 or 4 months easily,same with the stiff xtreme brushes although these will go out of shape within a few days its an easy fix(pour boiling water over them and theyll be like new again)i do this twice a week with the xtremes....

IMO its not just that hot pure water removes the insect spots,baked on bird muck on frames and glass,sticky pollen,grass cuttings,leaves,snail trails easier.....also hot water gives a better flow to your brush,windows rinse easier and dry much quicker and much more manageable hoses all year round.....

you boys carry on with cold water if your happy with that....i really dont give a toss anymore.....

 Dazmond, i agree with everything you have mentioned about the benefits of using Hot pure water, I've been using Hot for
 over three years now,  i live in Galway on the west coast Ireland, so being right by the sea, we get a lot of storms here, plus salt
 on the glass, the hot water just eats through it, plus all the seagull crap we get too.

According to alot of stuff I have read online, hot water gives a better flow but cold water sheets better on surfaces.
Also using hot water on hot surfaces creates a higher chance of spotting as the water will evaporate much quicker and before all contaminants can run off.
I can honestly say daz that i did not notice hot removing snail trails any quicker then cold, windows do not rinse quicker especially in warm direct sunlight for the above reasons. In fact in very warm sunny days I dare you to inspect the bottom edge of the glass, look very closely and you can see the water dries too quick and leaves spotting along the bottom. I noticed this a few times, even when rinsing with a high flow and 0ppm water. It almost looked like dry steam marks.

I have been using cold again for 2 days now, yesterday on a big medical centre and today on a load of houses and have noticed no difference in speed, ease of cleaning, hoses were perfectly manageable and the finish was perfect. I know this because I cleaned the inside of the medical centre after doing the outside.

Im thinking more and more that the best water temp is actually just slightly warm, particularly as we agitate the surface with a brush, then hot is just not needed.
The temp currently in my tank is 20c, I'm thinking of just heating the water to around 35c in the tank as I think that is more then sufficient for what we need without the added faff of killing brushes, risk of cracking windows, spotting on hot days and very very cheap to do.

Ps I have the stiff supreme brush, it just feels awful on the glass plus its just too small for my liking. There just isn't enough choices in terms of brushes for hot water.

[dazmond]

we will just have to disagree then mate...

IMO in terms of cleaning power,hot water is more beneficial in the warmer months because the water is very hot with no heat lost from the hose on the ground.... ironically enough the windows are dirtier in the summer months in regards to snail trails,bird muck,grass cuttings,insect spots,etc which very hot water helps remove far easier than cold water...

how can you say hot water doesnt help with snail trails?

as for spotting on the bottom part of the  glass with hot water,i dont get this either....maybe i just rinse more on hot days

Yes you do, the thought that somebody can clean as quick and as good using cold makes you feel foolish, hence the need to invent non existing problems for the rest of us.

Because snail trails are so easily removed without it as is most bird muck and insect marks, as for the rest, luckily my customers aren't untidy enough to leave grass and muck on their windows until I show up, there's not a single video out there of a hot user putting the so called extra speed of  hot to the test, I wonder why.

Sorry NK did do a hot speed video but I think did more harm to the reputation of hot than good.

somebody's on form this morning 


go on bu@@er off and clean some windows - and let the hottie's continue their luv in

I think the only time most of us even think of hot water is in winter when the water is much colder. I tested my water temp regularly last winter and the coldest it got to was 6.7c. At that temp water does slightly loose its cleaning ability as its closer to freezing point so its thicker and a weaker solvent, meaning its more difficult to break down and carry dirt with it.
All that's needed though is to bring the water back up to a suitable temperature where it is as effective as it is in the summer, somewhere between 17c and 25c. You don't need to spend 4 or 5k to achieve those temps.

[Den68]

I had immersion heater installed last year, used it every day in winter months purely to keep my hands and hose nice and warm  personally I did think the snail trails disappeared slightly  easier, I continue to use cold only until the weather gets very cold again then the immersion will be switched on again just for the comfort of warm hands and nice manageable hose.

Immersion heater is good value for money to keep van defrosted and for warm hands, but I wouldn’t pay  the many thousands of pounds for water on demand but each to their own.

any cold water wfp window cleaner who thinks removing insect spots,snail trails,bird muck on frames,etc is just as easy as using very hot water obviously has never used hot water for cleaning....it makes the job easier...just like xtreme poles and electric reels do....every little helps......
