i know a cleaner who cleans with cold and says he wouldnt dare use hot i dont agree just wondered what you little lot think
-
As hot as you can get.
-
me 2 he wont have it tho
-
Thats ok, just pick up his customers :D
Does he use m power by any chance?
-
no he goes in with a prochem small thing presprays with champion then goes over with cold water , i said to him do u wash your hands in cold water he then went on to explain what he charges for a lounge 5o quid and hes never had a complaint except when he shrunk a wilton i said thats to do with not drying it prop he said no heat well i just let him crack on each to there own hey

HERE ARE MY RANDOM THOUGHTS ON THE HOT/COLD DEBATE :D
I could clean a carpet with cold water and get it as clean as if I had used hot water but it would take a lot longer which is Ok if I've got lots of time and don't have another job to go to, but if you are busy and want to be doing 3-4 jobs a day then hot water will speed things up.
also if I only cleaned carpets that are not really dirty then cold water would be fine and to be truthful I rarely clean disgusting carpets but when I do I'm glad I have the option of hot water
and having the option to use hot water is the most important thing, lots of the cold water brigade say they don't need hot water which is a bloody good thing because (coincidental) they don't have it just like the manufacturers who sell machines without heat, they also (coincidently) say you don't need heat
I think the problem is people who say cold is as good as hot have never used HOT water only warm or at best very warm, if you can put touch the QC then its warm not hot ;) and it's when the water is really hot you see it at its most effective

I was told by Derek Bolton on a Cleansmart training course not to waste my money by having a heater on a machine,he said you can clean perfectly well with cold water.

What a bloody awful day ......... more snow so next weeks work looks like going tits up again, I'm skint so I can't go down the pub even if I could get there without slipping and breaking something.
I've already had to read that a 100psi porty will clean just as well as a truckmount...... and now no doubt the cold water rinse brigade will come on and tell me that I don't need heat to clean a carpet effectively.
I'm going bloody stir crazy in this weather !!! >:( ;D

Any body who has done any sort of serious training with hygiene or bacteria will fully understand the reason why heat is used and needed in cleaning.
-
Have a full breakfast tomorrow then rinse under cold tap and then rinse under hot tap.
Which breaks down the grease the most.
That's why I use hot.

Hot water extraction aka steam cleaning involves the use of hot water or it would have to be called cold water extraction.
If you told your customers you were going to clean their carpets with cold water you wouldn't be in business for very long.
No disrespect but your friend doesn't know what he is doing.

Steve,
Calm down dear. It's all just a dream.
Cold clean's as well as hot? what a load of tosh.
-
Derek uses a cfr machine (not the heated version) image Alex Ferguson saying that he wanted to buy Steven Gerrard? he may like the player but he would never ever say that he liked his closest rivals best player!
Now Derek knows how to get the best cleaning out of his machine but he won't advocate heat as he doesn't use it.

The first ever truckmount that i used was a Prochem 150. The water on those machine is heated via a parafin heater system. 90% of the work we did was night clubs. The machine used to SUPER heat the water which was ideal for cleaning the carpets in the night clubs however, on occasions we would run out of parafin & it was a nightmare trying to get the carpets clean to the same standard as the areas that we had cleaned with the hot water. Even domestics you could tell the difference. Hot water cleans better than cold regardless of what chemicals you use.

I think most cold water cleaners do a lot of pre spraying with hot water the cold water part only comes in at final rinse, the idea is to use the preparation to the max, vac the carpet until it looks as thought its had a smacked rs and then plenty of pre scrubbing the work is almost done before the rinse comes along.

Remember the carpet cleaners piechart. heat is a big part, well 1/4 of it ;D
-
spot on Shaun! i did a cold cfr year with some jaw dropping results but since i got hot my earning potential has tripled!!! serious no bull so there must be something that the heat is doing...... DOH!

Taken from ask a scientist
Question - Why do white cotton socks seem to
get cleaner in hot water than in cold water?
-----------------
Hi Camille!
White socks, eh? Usually white socks used with
tennis shoes get quite dirty.
When you wash them using common soap or detergent
cleaning at machine or by hand means to take off
the dirt from the fabric. Mostly detergents have
ingredients that are more soluble in hot water than in
cold one and that make them to work better.
Also the fabric itself in hot water gets more soft
the thread opens letting the dirt to get loose,
and the fabric gets cleaner.
All that happens with any kind of cloth not only
socks.

=====================================================
It is not an illusion, Camile. They really do get cleaner.
Heat almost always makes cleaning more aggressive, in any setting.
I can think of three common behaviors that contribute to this:
1) increased reaction rates - (kinetics)
heat speeds up all reactions, even those as humble as
water wetting it's way along the interface between some slime
and the fiber of your clothing.
2) increased dissolving abilities - (due to entropy)
even without soap, small amounts of some greases will dissolve
in water.
In hot water, the amount that will dissolve can be ten times higher.
3) melting -
some greases are low-melting waxes, and being melted makes it easier
for the soapy water to penetrate, detach, and surround them.
Even things that are not quite melted at least get softer.

Hi Guys
Hot cleans better for lots of reasons, reduced surface tension, molecules of detergent move faster, therefore greater penetration, dirt is softened by higher temps, particularly fats, fibres are opened up allowing easier removal of dirt etc etc
I did quite a lot of work on rates of reaction when I was a chemist and the three most significant factors are heat, catalysts and pH.
Don't get too bogged down with pie charts , these un are scientific and just a pictorial way of displaying information, they are certainly not based on any accurate experimentation.

That's a great idea, I'm starving. But why wait until tomorrow. :)

cleaning with heat cant be beat,thats what i was told some years ago on a training course

Here is some 'science' which Hydramaster quote on their site - I would have liked to see some US university quoted as the source but I dont believe they do actually offer a source but you've got to admit it reads well and is fairly easy to remember:
"It is a scientific fact that the hotter the water the better; for every 18 degrees fahrenheit rise in temperature over 118 degrees fahrenheit, chemical activity doubles. This continues until you reach a temperature of approximately 250 degrees fahrenheit. This happens with virtually any cleaning chemical."

There are folks that insist 200 degrees+ is the only way to clean, others who use M-Power or Nemisis or micro-splitters/detergent free who rinse with cold water and insist it is the way to go. I had a bit of time recently so tried M/S & Nemisis and powerburst on a really dirty greasy pub carpet, My machine has drop in pipes so it was easy to switch between cold and hot water, by the way hot as in 50 degrees or tap hot if you will. Neither M/S or Nemisis touched it rinsing with either hot or cold. Powerburst rinsed with acidic rinse at 50 degrees :D Powerburst did out perform others even with a cold rinse but it was no where near as good. Agitation used in each test 250 psi. Am I right to consider my test as definative. NO. I can't get the results others claim but I don't discount their experiences, different strokes for different folks. Try it both ways and make your own judgement. I still use M/S and Chemspecs DFC on certain domestics that don't require higher Ph cleaners, normally wool or blends with moderate soiling and with good results, DFC i've found has the edge. Pre Spray Gold still does the business too. After years in this business i'm still trying new techniques and solutions but I find it's best to try it yourself, that's what makes it interesting 8)
