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
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]

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 !!!

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.

[Shaun_Ashmore]

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.

[trevor perry]

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.

[Mike Osbourne]

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.

[carlton care]

Thanks Trevor, that's all I wanted to know
