we all here a lot of people talk about Eco cleaning and how cleaning with cold water will some how save the planet. Or how hot water is not needed and they can clean just as well with cold.

We did a Chinese restaurant today the carpet was grafted. we did some filming to show the what can be achieved with just hot water, no prespray or agitation just the power of very hot water.

this is the most eco clean you can get.... NO CHEMICALS ARE USED

its a rough first edit so the filmings not to good

Hi Mike

Thats a great demo of the importance of hot water but aaaagggghhhh I had a very similar idea on this ver subject for something. I'll talk to you about it in Stoke.

Pete

[Mark_Jubb]

Got to hand it to you Mike, that's a pretty impressive demonstration of your equipments capabilities

[richy27]

correct me if wrong but is water not a chemical sorry to b the smart arse

[Mark_Jubb]

I seem to recall somebody once refering to water in a training course as "the universal solvent"

[Colin Day]

A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory.

[Steve. Taylor]

Took the words right out of my keyboard colin.  :-\But i still  like the video clips Mikes doing think this is the way to go the videos that is fair play. Cant fault the quality of the kit being used. bit like the clip on Ashbys. site but a tm instead.  

[Mike Halliday]

Colin how could that job have gone any quicker? we could have pre-sprayed and scrubbed it but look how quick we cleaned with just going straight in with hot water

and yes water can be classed as a chemical, but I think we all know what point I'm making

and we achieve steam like this from start to finish,  we had to turn it down, the first film we made you couldnt see the wand for steam

[Neil Williams]

How hot was that water because it looks close to steam cleaning?
There's no doubting that steam works because afterall that's what they use to cleaning oily and greasy engines

[Dennis]

Be interesting to see a section done with hot and a section with cold.

[derek west]

be interesting to see if theres any wick back after a few days.

nice to see you doing your own vid's mike. not hard and for our game you don't really need a professional one all though i'm not knocking them.

ps... like the driveway / pathway one. impressive.

Hi Guys

Water is known as the universal solvent because more things are soluble in it than any other liquid.

The trouble with water is that because of it's high surface tension it does not wet out very well and this is one reason why we use detergents.

It would be interesting to note whether the carpet contained shampoo from a previous clean?

Cheers

Doug

[Mike Halliday]

Doug I was the last clean, I do this carpet every 3months. I usually rinse with chemspec high heat so that would have been in the carpet from the last clean but not much of it to make a difference

is'nt the surface tension of water altered by the temperature? this was at 400psi 4 x 02 jets. the temp was hovering around 90degrees

[John Kelly]

Cleaning some fabrics and materials with just water can leave a "harsh hand" don't know why this is, maybe the disolved minerals in the water cause some stiffness when the moisture evaporates off, don't know.

Probaly wouldn't make much difference on that carpet though.

[Doug Holloway]

Hi Mike

Couple of interesting links, units are different but it's the comparison we are after.

So yes surface tension decreases with increasing temp but not by that much, approx 20% range.

Also Water has the highest surface tension of all the liquids listed with the exception of Mercury!

Interesting experiment though.

Cheers

Mike ,
This is exactly were the burners come in to their own , correct ?  as you know imyself have to keep my heat turned down as it can get to hot imo, but the beauty of it is it is instant  and constant unlike other heating systems in the vast majority of machines.
I would be interested to know exactly what the comparisons would be from other t/m users with other methods of heating ?   i dont mean quoting figures from a manufactures hand book, but the realistic facts from users.

[james roffey]

Dont you guys know anything, heat make no difference

[Joe H]

Anythings possible, James, after all its now been proven that chemicals make no difference - and thats a big slice of the pie chart gone. (made up by a bigger slice of something else ie high heat).

[Colin Day]

Dont you guys know anything, heat make no difference

  I bet it was the heat that melted the grease on that carpet, that wouldn't have happened with cold water.... Surely

[Ken Wainwright]

An amazing and effective demonstration. But logic would suggest to me that an emulsifier would have performed a more "lasting clean" ie removed even more contaminant. And a pre spray with agitation would have moved it on another notch. And, perhaps, this combination could have speeded up the rinsing process.

If you are thinking along the lines of more Eco Friendly, you need to also look at the carbon footprint too. Apart from energy consumption on site, you have to weigh up, presuming that the use of chemical performs even better than the demo, that more frequent visits may be required.

Safe and happy cleaning
