Hi Richard

Definitely a factor in the promotion of cold cleaning.

Cheers

I have actually cold water cleaned for a period in my business and although i still got good results as i uped the agitation stage  . the biggest factor i found that caused me problems was my drying times am convinced that hot water cleaning means drying times are reduced

[Jim_77]

Probably your equipment that hot water cleans has more suck than the kit you used with cold

Even with a steaming hot TM rinse, the temperature of the carpet returns to ambient within a minute or so presuming a decent drying pass has been made... if it stays hot for any length of time, you have flooded it full of hot water and it'll take an age to dry anyway!

Hi Guys

Hot water will evaporate faster, laws of physics again.

Although it will cool rapidly it will still have more energy that cold water and therefore  a faster rate of evaporation.

Cheers

Yes I agree on the heat and evaporation - like others say, just basic common sense.

Ideally to have any sort of leverage in a debate such as this you should really be accustomed to (and own) all methods in order to have a balanced outlook.

I've just completed my 21st month so I'm not dated with old styles of cleaning. I was taught most of what I know by the cleantalk forum and the promotion of cold water systems, namely colloids and splitters rinsed with plain cold water and a triple vac. I still have this system, BUT I also have a truckmount. With that I use all types of solutions allbeit mainly detergents.

What I do know though is whatever I'm rinsing out, MS or detergent I notice a marked improvement in results from the beginning of rinsing while the water is warming up to the end when its piping hot.

Hot water does a better job on anything with anything full stop, even without solutions or rinse aides you can clean with scalding hot water and I think for anyone to have a relevant opinion they should have ready access to all types of cleaning, not just one.

to put another spin on it  cold water cleaning became very popular as porties got bigger eg triple vacs etc would it not be the case that many of the manufacturers embraced cold water cleaning so they could reduce the amount of power cables required.

just my opinion    PS i love heat and my truckmount

 I know what you mean , but i wouldn't agree with the above as no machine had the amount of cables reduced , a triplevac would be a twin cord anyway .   If you mean going without an inline heater , then perhaps , but i doubt it would concern any porty manufacturer .  But i'd say MS was promoted on cleantalk in the scorpion era , and as it had no heat , perhaps thats where the cold water MS thing started .

Just looking through some posts on this forum ( searching microsplitting )  from 2004 up , ( some of you guys were arguing all this way back then )  some nice posts from doug countering the various claims made by the MS promoters .  the whole cold water vs hot thing doesn't seem to feature much early on , seems it developed some time later ? and the original MS distributors were selling machines with heat in the beginning   it seems .
The whole MS thing seemed to center mostly around a claim that ' detergents ' ( which would need to be defined )  cause resoiling .    But offer no proof as to how significant , if at all , resoiling is .   :

Never mind all the science behind hot v cold, when you are working in an empty house with no heating and the outside temp is hovering around the zero mark you need a bit of warm water around you.

So yes heat is a massive factor to doing a good job, scientific laws. Lots of peple with experience. Common sense.  Welshmen with handbags at 20 paces. Who are the people to dispute the facts? ?

Was that an opology Peter?

ugh me like hot steam!

at 1500psi and 150c not a lot resists the absolutely awesome effects of vapour steam

or 80 sq meters of pub that look like this in 1 hour and dry in 2 ready for opening

show me the cold system that eats blacktop and dry in two hours? I buy it in a heartbeat as TM are not cheap.


P.s that a a Belgium wilton as well.
