[The Carpet Cleaning Pro]

As we all know heat is good but how hot do you go?

[Simon@arenaclean]

I rinse with 'tap hot' water, about 50C, have tried but never got on with cold water. I've toyed with buying an inline magma heater but the process I use gives excellent results so not sure I need it.

[Colin Day]

Some products can be used hot or cold, but if I'm using orthodox solutions, I like the heat at 60-70 degrees....

[garyj]

On Poly,  270 degrees and 500-600 psi, use loads of water but the results are great.

the level of depends on what method you are using.



each element will grow and reduce with each method but the total pie is the amount needed to clean.

for example in my method pie my chemical slice is much larger and i don't have any mechanical as i use dwell time and don't scrub most cleans. now if i was using a TM my temp would be high and i would then be able to reduce other slices.

what great about this is that each one of use our own pie but will end up with the same result.

Truckmounters will know that jobs requiring a really high temp. also require a solution that can cope.  Whether it is a powder or liquid to make up the stock solution, if it isn't designed to work very hot it will degrade, break down (manifested by blocked jets) and not work.  That's why I have a shelf of unopened bottles that I used to use in my portable.

Hi guys

With the greatest respect Ian the 'Cleaning Pie ' is a schematic and has very little scientific basis other than as an aid, is certainly isn't proportional.

As for optimum cleaning temp it will depend on too many factors to be meaningful.

Basically hot cleans better and the hotter the better on 90% of carpets

sorry mate it does have a science base. just out of interest have you read Eric Browns books?

In the foreword and i quote " in sort on one hand a practical guide for practical people while on the other hand containing enough scientific data from research carried out around the world to interest the scientist"

and from a man of science like yourself i find it hard that you dont give out any of those "As for optimum cleaning temp it will depend on too many factors to be meaningful" break it down and you will come back to the Sinner circle.

Sorry I am only the messenger.

In your defence all those "factors" are us. every cleaner uses a different machine, products, method. but they all fit into sinner circle just at different size slices. also optimum clean also comes from knowledge of the environment of the very type of bond between the dirt and carpet. what surfactant does it need and does it need mechanical action to release the bond?

just ask yourself s why do carpets get soaked by new cleaners? its because they keep going over and over the carpet without releasing that bond. that's why no one product is available to use.

its not magic, just science. as i have said before I have never seen Eric's knowledge tough on any other place apart from his book. armed with sinners circle and knowledge of surfactants any new cleaner would find cleaning so much easier.

Everyone should read all the books published by cresta  they are the foundation of cleaning.

I think 'heat' has been the victim of a smear campaign over the last few years,  some people & companies have been down-playing its roles in the cleaning process, this I think is due to the fact they don't have it at their disposal. its like the saying..... size doesn't matter but its always quoted by people with small appendage.

a manufacturer of machines that doesn't have heat will give every reason in the world why its not needed and the same with trainers who use portable with no heater, how can they stand in front of a class and tell the students  they need heat.... but then say they personally don't have it as an option, much easier for them to cover themselves by teaching the importance of the other part of the cleaning pie.

if we go back to the basics of cleaning. 85% of the dirt is dry soil which will be removed with a thorough vacuum this leaves 15% of soil which is the bonded dirt that is attached to the carpet fibre. It is mostly attached with an  'oily greasiness' I  can't think of a better name for it but lets call it 'glue'.

we can attack this 'glue' with chemicals or physically scrape it off with agitation but the simplest way to alter grease or oil it to increase its temperature, some try and dismiss the effect of heat by saying...... "hot water will cool within seconds of hitting the carpet, so does'nt have time to have a real effect on the dirt"

But try dripping hot water onto butter and you will see how how quickly hot water effects grease or drip very hot water onto your skin and you will see the effect of hot water before it has time to cool. now think of the effect of a high flow wand putting a significant amount of hot water onto the carpet.

you can clean without heat but why use more chemical ( not very eco) or harmful agitation if you have a more useful tool at your disposal.

[Doug Holloway]

Hi Guys

Ian the point I am making is that the cleaning pie is an aid to memory but it is not proportional and therefore has limited scientific use.

What I mean by proportional is that if say you increase heat by 10% does that mean you reduce agitation by 10% and get the same result!

As for the optimum temperature this will depend on the type of fibre, type of dirt, chemical being used, different ones will work better at different temps etc and there really isn't a simple answer.

In my view as I have previously said in most cases high heat, say 70C will give you a much better clean than 40C.

I am convinced one of the main reasons a lot of CC's struggle with upholstery is that they clean too cold.

Hot water is the ultimate eco clean. I have cleaned a number of carpets with v. hot water, huge flow rate and no chems. Heat is good.
