Was doing a job today via wfp when a member of the public asked if I was using “hungry water” because his mates a windy and that's what he uses I was speechless any 1 else heard of this

Never heard the term before but it is accurate. Di water, being altered from it natural state, at 0 TDS will, like all naturally occuring things, attempt to return to it's natural state. As rather than washing dirt away it consumes it (look what it does to algae without any scrubbing) hungry seems pretty apt.
-
I tell them its called "Magic Water", especially when a customer uses their hose pipe to wash the windows down and it leaves spots whereas mine doesn't.
-
I've had customers call it "Special Water" and "Super Water" ;)
-
I like to call it very clean water ::)

What a load of old dross. It works by washing/rinsing the crud on the glass away and subsequently not leaving mineral deposits on the glass because it is pure water itself (i.e. zero or low T.D.S).
Id love to see the evidence that half the guys come up with on here, its generally vicious rumours what you read on here or conspiracy theories ;D
Where did you hear that stuff E and M? Who told you that or where did you read it? ;D

my brother had this drivel (no offence E & M) on his info leaflet when he went wfp 8 yrs ago I thought it was over cooking the goose then. I preferr AND USE Matts much simpler explanation when explaining to customers.

go to a really crappy clean some of it with normal tap water,then the rest with pure and let us know the difference. apart from the spotting! ;D
i think in a overcomplicated way he was trying to say the more pure
the water is the more an aggressive cleaner it becomes.

It was the result of an experiment about 25 years ago using water with 0 tds.
We placed a pair of algae covered glass sheets into a pair of metal trays.
One tray contained 0 tds water and the other tap water.
The purpose of the experiment was to see what would happen to the algae over a 24 hour period without agitating the glass.
The result was that the 0 tds water had consumed the algae from the glass with around 90% effectiveness, probably 100% with more time.
The tap water tray water was green but had only dissolved about 20% of the algae over the same time scale.
Window cleaning wasn't the aim of the experiment it was actually to test the viability of pure water in cleaning external masonry paintwork prior to refinishing (in my past life I was a painter before becoming a window cleaner) and it was indeed found to be extremely effective.
Conventionally I used to use a bleach based algae killer prior to repainting but it was hard work to apply as it had to be done by brush.
Used to neutralize and rinse with tap water from a hose, which as long as the solution was left on for 24 hours, and it didn't rain, used to get the algae off ok.
Tried to shortcut this by just washing the algae off with a flexi brush, hose and tap water but it was incredibly slow.
Last house I painted, took my truck and cleaned the walls down with pure water. Took probably a quarter of the time of tap water as rather than just loosening and washing away, the algae was being consumed.
Seriously though: Has no one noticed that when you get run off on the cills it cuts a swathe through any greenery on the wall?!
That's what reminded me of the painting experiment 25 years ago, because too be honest I'd forgotten all about it!
Why do you think that rainwater doesn't have the same effect?
-
Eh?Rainwater is nearly pure ???
-
I tell them its called "Magic Water", especially when a customer uses their hose pipe to wash the windows down and it leaves spots whereas mine doesn't.
people used to say to me "are you the cleaner with the magic water"
its where my business name came from
-
pure water dries my hands out really bad.im sure its cos the water is soaking up the nutrients in my skin more than normal water.
pure water is definitely more "aggressive" and its mildly solvent.google "dionised water" and you ll see what the real experts say.
i agree with EandM.

i'd agree with that when i do some upvc cleaning soffits etc and some water splaces on me face it comes up all red two sides of my nose and all dry sore sometimes too. only happens on the pole.. look terrible

sorry ... many apologies ;)
.... was on an Ionics training course when I first started and Craig told me that H2o when purified is summit like H16o so has to get back to its natural state of H2o so along lines of what someone said about it eating the s hit up

Health effects of drinking purified waterDistillation removes all minerals from water, and the membrane methods of reverse osmosis and nanofiltration remove most, or virtually all, minerals. This results in demineralized water which is not ideal drinking water. The World Health Organization investigated the health effects of demineralized water in 1980, and its experiments in humans found that demineralized water increased diuresis and the elimination of electrolytes, with decreased serum potassium concentration. Magnesium, calcium and other nutrients in water can help to protect against nutritional deficiency. Demineralized water may also increase the risk from toxic metals because it more readily absorbs them, and because the presence of calcium and magnesium in water can prevent absorption of lead and cadmium. Recommendations for magnesium have been put at a minimum of 10 mg/L with 20–30 mg/L optimum; for calcium a 20 mg/L minimum and a 40–80 mg/L optimum, and a total water hardness (adding magnesium and calcium) of 2–4 mmol/L. At water hardness above 5 mmol/L, higher incidence of gallstones, kidney stones, urinary stones, arthrosis, and arthropathies have been observed. For fluoride the concentration recommended for dental health is 0.5–1.0 mg/L, with a maximum guideline value of 1.5 mg/L to avoid dental fluorosis.[19]
Water filtration devices are becoming increasingly common in households. Most of these devices do not distill water, though there continues to be an increase in consumer-oriented water distillers and reverse osmosis machines being sold and used. Municipal water supplies often add or have trace impurities at levels which are regulated to be safe for consumption. Much of these additional impurities, such as volatile organic compounds, fluoride, and an estimated 75,000+ other chemical compounds[20][21][22] are not removed through conventional filtration; however, distillation and reverse osmosis eliminate nearly all of these impurities.
The drinking of purified water has been both advocated and discouraged for health reasons. Purified water lacks minerals and ions such as calcium that play key roles in biological functions such as in nervous system homeostasis, and are normally found in potable water. The lack of naturally-occurring minerals in distilled water has raised some concerns. The Journal of General Internal Medicine[23] published a study on the mineral contents of different waters available in the US. The study found that "drinking water sources available to North Americans may contain high levels of calcium, magnesium, and sodium and may provide clinically important portions of the recommended dietary intake of these minerals". It encouraged people to "check the mineral content of their drinking water, whether tap or bottled, and choose water most appropriate for their needs". Since distilled water is devoid of minerals, supplemental mineral intake through diet is needed to maintain proper health.
The consumption of "hard" water (water with minerals) is associated with beneficial cardiovascular effects. As noted in the American Journal of Epidemiology, consumption of hard drinking water is negatively correlated with atherosclerotic heart disease.[24] Since distilled water is free of minerals, it will not have these potential benefits.
Where a public water supply contains significant fluoride, naturally or added by fluoridation, people who prefer to limit fluoride intake can install filters appropriate to reduce fluoride content, although this may harm dental health.[25]
DeionizationDeionized water, also known as demineralized water[2] (DI water, DIW or de-ionized water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.
Deionization does not remove the hydroxide or hydronium ions from water. These are the products of the self-ionization of water to equilibrium and therefore are impossible to remove

Need to have a lie down now ;)

you get some in your eye and you know there is a diffrence between normal water ;D ;D ;D ;D ;D

Happened to a mate now hes blind ;) ... ate all the way thru his eye and didnt stop till it came out of the back of his head ...
we now call him "Polo" as big hole in the middle of his head .... I kid you not

Never heard the term before but it is accurate. Di water, being altered from it natural state, at 0 TDS will, like all naturally occuring things, attempt to return to it's natural state. As rather than washing dirt away it consumes it (look what it does to algae without any scrubbing) hungry seems pretty apt.
What a load of old dross. It works by washing/rinsing the crud on the glass away and subsequently not leaving mineral deposits on the glass because it is pure water itself (i.e. zero or low T.D.S).
Id love to see the evidence that half the guys come up with on here, its generally vicious rumours what you read on here or conspiracy theories ;D
Where did you hear that stuff E and M? Who told you that or where did you read it? ;D
Why is demineralised water not suitable for consumption?
There are three evident reasons:
Demineralised water is highly aggressive.
Its distribution through pipes and storage tanks is not possible because the aggressive water would leach metals and other materials from the pipes and other plumbing materials.
Demineralised water has poor taste and thirst-quenching characteristics.
This is again due to its lack of minerals.
Demineralised water has been proven to have adverse health effects for humans, due to the deficency of certain constituents. This is further documented in the following paragraph.
What supports this theory?
There are a number of studies, conducted by health professionals in different parts of the world, which support the three statements above. Here is an example of some of these studies and the resulting conclusions:
Rahmmanin et al, 1989. Study conducted on rats. Conclusions: distilled water caused decreased secretion of tri-iodothyronine and aldosterone, increased secretion of cortisol, morphological changes in the kidneys (including a more pronounced atrophy of glomeruli), swollen vascular endothelium limiting the blood flow and reduced skeletal ossification in fetuses.
Studies conducted on human volunteers by the WHO, 1980. Conclusions: low mineral water consumption increased diuresis (almost by 20%, on average), body water volume and serum sodium concentrations, decreased serum potassium concentration, increased sodium elimination.
Robbins and Sly, 1981. Study conducted in patients who received balanced intravenous nutrition diluted with distilled water. Conclusion: The intake of low mineral water is presumed to be responsible for an increased elimination of minerals from the body.
Study conducted by Basnyat et al, 2000. Conclusion: Ingestion of several liters of low-mineral water following intense physical efforts may cause severe acute damage, such as hyponatremic shock or delirium.
Epidemiological studies by Sauvant and Pepin 2002; Donato et al. 2003; Monarca et al. 2003; Nardi et al. 2003. Conclusion: Soft water and water low in magnesium is associated with increased morbidity and mortality from cardiovascular disease.
Study conducted by Verd Vallespir et al.1992. Conclusion: Intake of water low in calcium is associated with higher risk of fracture in children.
Jacqmin et al.1994. Conclusion: Intake of water low in calcium is associated with certain neurodegenerative diseases.
Yang et al. 1997, 1998, 2002. Conclusion: Intake of water low in calcium is associated with pre-term birth, low weight at birth and some types of cancer.
…and a very long etcetera of properly conducted experiments, which demonstrate what the World Health Organization is also claiming:
The WHO published in its latest report available (2004), that it has been adequately demonstrated that consuming water of low mineral content has a negative effect on homeostasis mechanisms, compromising the mineral and water metabolism in the body.
