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.

Got to hand it to you Mike, that's a pretty impressive demonstration of your equipments capabilities
-
correct me if wrong but is water not a chemical sorry to b the smart arse
-
I seem to recall somebody once refering to water in a training course as "the universal solvent"

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. ;)

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

Hi Mike
http://www.surface-tension.de/
http://www.engineeringtoolbox.com/water-surface-tension-d_597.html
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.

Dont you guys know anything, heat make no difference ;)
-
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).
-

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

to say that......if had used a prespray and rinse I would have moved the cleaning up another notch is to suggest that my cleaning was not already on the top notch :D
this job is not a typical job we clean it every 3 months as ths carpet leads from the kitchen and get a heavy deposit of grease. we did actually pre-spray and scrub the rest of the job, but this area was left because I wanted to test ( & film) a demonstration of how effective heat can be.
there was no visible difference in the carpet between this area and the scrubbed section, we scrub with a rotory and then post bonnet. We could see from the bonnet if any dirt had remained after the freshwater clean.
with the other section I turned down the temp as I get sick of burning my arm on the QC when using very hot temps.
the conclusion of this demo was that on this particular carpet i could achieve the same level of clean with the power of heat. some chemical are sold on not containing any harmful ingredients (eg; Microsplitters) so if you are serious about cleaning without harmful chemicals how can you not use heat
-
You can hardly call it ECO cleaning, hot water costs fuel.
-
Mike, perhaps the hot water alone has removed just as much soil as best practice procedures. For us on the job tecs. we just wont know for certain.
The post clean bonnet is not a definitive indicator of remaining soil as the blackness is soil ATTACHED to the oils/grease/fats. The oils thenselves are typically clear or very close, so you won't tell visually if there's much remaining. And being in a high traffic/soiling area, you probably wont see much difference on a day to day basis because the installation is being managed/maintained so well.
Still a great demo and topic though :)
Safe and happy cleaning :)

very impressive mike but i will say that i have found that chinese restaurant grease and indian restaurant grease seem to be 2 different things. the next time you are cleaning an indian restaurant, try the same test, i'm not so sure you will get the same result,

I think you have to look at the way the carpet is cleaned, the carpet wasn't just steam cleaned but looked very well flushed with a high flow, I wonder if when more procedures are added but the flush is lesser if the soil is suspended but not flushed away therefore leaving particulate soil to reform?
And that's not to take drying into the equation.

Yes looks impressive, but what I would like to see is the carpet a few days later, coupled with this I would like to see the same results when you clean the carpet again! ???
Over the many years in business I have followed up on the cleaners that use sheer Power and blistering temperature to achieve a clean, whereby I always hear the customer say the same thing: “when he fist cleaned the carpet it was great but when he did it the second time it was not so good”
The reason it that the cleaner who uses so much heat strips the goodness of the carpet leaving it week and limp, in other word’s his has kicked the crap out of the carpet. To prove my point do another film a couple of month later and do the same clean and compare like for like. :'(
-
just out of curiosity brian, why the long wait? :)
-
Could be Brian's a slow reader Derek ;D
-
;D
i'll probably get the blame, i usually do. ;D

strips the goodness???? what a load of crap, leaving it weak & limp..........are we talking about a bloody lettuce??
obviously you are taking the mickey ::) ::)
-
Could i just ask about using heat.I have a Scorpian supplied with a 2 jet wand. I have a Ashbys steamate in line heater. If i crank the heat up 2 60 deg i find my wand start to drip from the trigger.
Do you need a special wand or one fitted with upgraded seals to handle high heat.
Thanks
David

David
My wife complain's about 'trigger drip' all the time ;D
-
Prob heating the seals up and they expand mate with the extra heat..
-
Clinton was that an answer to Adrian?
There you go Adi you need to replace your seals ;D
Image if just if...
You were to pre vac, pre spray and dwell, aggitate and hwe in the way Mike did? now that would be a clean!
Shaun

Shaun, off to the Doc's for replacement seal's 8)
I assume your second comment WAS about carpet cleaning ;)
By the way, did a job for a Sheff Wed player yesterday, a certain Darren Potter, friend of yours?
-
Mike weak & limp next clean try viagra that will sort it ;D
-
Shaun thats your dirty mind ;D ;D
