has anyone heard about pure water carpet cleaning ,aparently its like the window cleaners out there with their osmosis water purification machines and the water is fed to the t/m water tank .
I am told that purified water is very aggresive on dirt and this is all the rage in america.
As I say not seen this before ady ::)

Asked the same question some time ago, but got no response. If it does what it appears to do, It should give a good result

I use Evian mineral water for all my HWE but it works out quite expensive, I did try volvic for a while but didn't get the same results.

here's the next generation of 'green' pure water cleaning

roll on acid rain then i don't have to buy fibre and fabric rinse.

Tennant are probably ahead of the market here..............anyone who reads the window cleaning site will be aware of the exceptional results from " pure " water cleaning, maybe some of the crossover guys can enlighten us

WHAT :o
Pure water should have a TDS reading in the region of zero ppm. Tap water varies across the country but varies between 60 and 400 ppm. Mineral water is nearly a solid compared to pure water as most have a reading well in excess of 500 ppm.
You can't clean with mineral water.
I used to think that pure water was aggressive but over the years I've stopped believing that. What you will be doing by using it is NOT leaving any deposits behind and carpets should feel softer for that very reason.

Is softened water as good as pure for cleaning?

Cleaning capabilities....no
Softer finish to material...yes

Ady again ,why I am asking is because I am looking around all the t/m companies to get my first t/m and I said ,whats the future, and woodbridge say in america this is the in thing and say its very good , and will be over here soon ???

Neil I wasn't serious !!! ;D

Has to be RO as DI is corrosive to pumps.
RO=Reverse Osmosis
DI=De-ionization

Shaun, Im a pure waterfed pole window cleaner as well as a carpet cleaner.
I use RO+DI to clean windows pumped through a 100psi shurflo pump, i have used the same pump for the last 3 years and its still going strong. Pure water is corrosive if it comes in contact with untreated metal and is extremely damaging to wooden window frames.
Im not sure how pure water will be better than normal water for cleaning carpets, but I carry 650 litres on the van so i think i will try this theory on a old bit of dirty carpet i have for testing, and i will post the results here when done.
Just to let you all know its not the pure water that attacks the dirt on windows its the brush on the end of the pole that aggitates the dirt free then the pure water rinses it away leaving no water or streak marks; its called the typhoon effect.

Yes you are correct thinking on it's the heat exchanger on TM's that gets rogered and also thinking about it the brass quick connects.
There was a guy on truckmounters called Lance Golden that used RO for cleaning carpets that said that DI wasn't anygood for TM parts.

Yip well that would explain alot, but i still dont get the DI bit because RO removes about 98% TDS and the DI removes the remainder, there is absoultley no impurities including trace DI elements in the water after the DI.
So only one conclusion can come from this theory: RO & DI will rot the heat exchanger unless its made from stainless steel or has a protective coating to stop decay.

We use pure water for our window cleaning side - 5 years. Can't say I've noticed any problems with brass connectors, stainless steel or much else other than powder coated aluminium.

there is no way pure water can clean aswell as chemicals that is why most window cleaners with wfp who clean consevatories or soffits etc usually spray them first with tfr to remove the dirt, as a rinsing agent then it may flush chemicas out better than tap water but thats about all it would be better for.
and yes i do window cleaning aswell as carpet cleaning.
-
Glass isn't exactly the same as a sticky pile carpet is it.
On the otherhand if you have TM pressures and volume that might work.
-
Thanks Trevor, that's all I wanted to know
-
funnily enough i tried this today! Reason being pure water treats dirt like a magnet as it is in a unnatural state, anyway thought i would try. did my usual new build type stair carpet pre spray agitate prochem traffic lane cleaner and then rinsed with just water, i could not say any great difference but did seem to need less effort and carpets def softer. will do trials on dif bits and bobs

As a porty user, I am being educated a little by this thread, so thanks.
Question.
Whilst I am beginning to understand the different consequences between Reverse Osmosis (RO) and De-Ionisation (DI), is there much of a difference between RO and the water filtration that many TMers have on their equipment?
Safe and happy cleaning :)

Ken have a water softner fitted in van for TM. TDS reading in my area is 400+. After going through water softner TDS reading is about the same.

Hi All,
I've been using pure water rinsing since last march and works great it even gives an increase in the water temperature coming from the machine, and saves a fortune on chemical costs, in my experience in that time I find the chemspec dfc chemicals work the best when used as a pre spray.
All the best

What do you do John? apply DFC by hydraforce or pump up? rake in or scrubbing machine?
Shaun

Hi shaun,
I use a hydraforce and an envirodri machine that seems to do the trick.
All the best

Ken, I believe that truckmounters who live in a hard water area would use softened water to increase longtivity to pumps etc (no scale) also softened water is "creamier" so you would use less dertergents hense saving a few bob.
David, Your softened water will be the same tds reading as your normal water if not higher as it is only softening the water and not removing the minerals etc
In my opinion pure water is in fact not aggresive or whatever people think it is, in fact it is just plain water without the minerals in it which would cause spotting on windows.
So to use pure water for carpet cleaning as a rinse after a microsplit prespray is fine and it can be used with your favourite detergent but dont expect any better results!

Well i did my tests and stu is right, absolutley no difference in cleaning power, this looks likes its another one of those old wives tails. Im quuite dissaointed really i thought we had stumbled across something exciting. Never Mind. :'(

It's always worth experimenting, as long as it's done safely. Having read the posts from window cleaners about " pure water "I've been curious about the possibilities, thinking the p/w was responsible for the magical results on plastics and conservatoties, etc.

When i do conserv cleans a certain amount of TFR has to be used to dissolve the green stuff and dirty water marks, all pure water does is rinse away the TFR and leave a spot free finish. If pure water wasnt used, to obtain perfect results you would have to dry off the whole conserv leaving no water traces.
Pure Water is only magical for leaving a spot free finish not for eating grime.

If you mixed a chemical cleaning solution or MS with a water TDS reading of say 90, would that increase the cleaning capability against using a TDS reading of 400?
No proper studies have been made public which could explain the reason some people swear by MS and others hate them

On some dirty carpets I've pre sprayed and agitated but it's still left some stain in the carpet.
After HWE with some Double Clean in the water the stubborn stains disappear.
You trying to tell me that just hot water will do it?
Could save a fortune on chemicals if it were so.

Absolutley Not. I did this test as stated in a previous post. I tried pure water on its own = No Difference in cleaning power and i tried pure water with double clean = no difference in cleaning power. There you go i have released my findings to this closed forum. If you dont beleive me, next time you see a wfp window cleaner ask him nicely for some pure water and try it yourself. Hope this clears the pure water carpet cleaning myth up.

I'm not going to name the companies responsible but some years back when window cleaning by water fed pole and pure water was being pushed, these manufacturers/companies sold it as aggressive water because pure water can't exist naturally.
It sounded feasonable and we dutifully sold it to our customers as such, magic water and all that.
Some window cleaners were ill for a few days after drinking the stuff which backed up the 'aggressive name.' What it actually was, was that the resin that the water travels over was poisionus, but there are now 'food grade' resins that do the same thing but can be drunk.
The reality and all that is actually different. Pure water is just tap water without all the 'add ons' that it picks up on it's travels or which the water companies stick in it.
So as a 'cleaning agent' not much good, but should give a softer finish to materials cleaned as a rinse agent.
