Just by following the threads I can see that there are supporters and detractors on both sides. Everybody has an opinion. (A bit like football!!!)

Has any independent organisation done a scientific comparison?

It shouldn't be too difficult to do, should it? And it could be something to do at Carpex in March.

Why doesn't somebody:

(i) get a length of carpet from a walkway where it's pretty uniformly dirty along its length,

(ii) cut it in three equal pieces and then

(iii) clean each one by a different method.

(iv) Then do a HWE on each section and see what, if anything, comes out.

Or maybe it's a job for TACCA.

[gwrightson]

well i certaimly know which the superior clean, how ever i do use lm on ocaasions  ,does that give you some indication 

As for independent  !!!! why are you suggesting tacca are independent ? as as far as i can gather if you do not have hwe  you are not considered for membership, hardlu independent imho .

a range rover, an F1 car and a seven seater galaxy, which ones best?

answer is none of them and all of them,

now if you own all 3 and have the knowledge to know when each car comes into its own, then you'll always be a winner. simples.

Yes, I take your point, but it's not really a very useful comparison. I'm not suggesting that we compare racehorses and donkeys, they are similar animals for different purposes. I'm suggesting comparing different methods of cleaning carpets, which are different animals for similar purposes.

So I still think it's a fairly valid question: Which method would get the best results on three similarly soiled samples of carpet?

[Craigp]

Do you mean dry foam, absorbent pad, dry compound?

But any way all low moisture cleaning is only categorized by the IICRC as 'interim cleaning' it has it's place as maintenance cleaning program BUT is only to per long 'restorative cleaning' which is HWE

Clearly the industry is more advanced than you give it credit for, Perhaps you should buy the IICRC S100 standard reference guide for carpet cleaning it costs £85 ouch! But it's the most comprehensive guide to carpet cleaning ever put together!

It's worth having to refer too.

i was pointing out that all jobs are different, if your saying just a piece of carpet with easy access then its a no brainer, HWE everytime will do the best job. everybody knows that.

I've got all three and use all three. Don't know about the knowledge though

what? including the F1 car? 

[garry22]

Yep, I'm going to use the engine to drive the world's first 800 brake horsepower truckmount.

That would power some blower!

I'm not trying to be funny or offensive or anything untoward, but there are lots of things that everybody knows and turn out to be old wives' tales with no basis in truth at all. There are other things that everybody knows are old wives' tales that turn out to be perfectly true. The difference is only found by a proper scientific investigation.

If IICRC has done a scientific study and come to a clear conclusion, then that's the answer I was looking for.

[Colin Day]

I have all 3 to hand, but use HWE on 98% of my work.. (At a guess!!!)

I do have success with all 3 methods, but I believe HWE offers a deeper clean....

[Craigp]

Yes IICRC have done tests in the states and yes HWE is more effective.

LM has it's place for maintenance clean but it's recommend that it's broken up with restorative cleaning to remove the residues and soil left behind by LM cleaning.

[garry22]

So what happens when I get called in to deal with the left over residues from a HWE "clean" on a low profile office carpet that looks worse than before they started?

[Mike Halliday]

tell them next time get someone it who knows what they are doing!!

 it wasn't the method that caused the problem but the operator

[Seymour Sunshine]

So ... Let me get this straight:

gary22 has all three systems.

his website says that he can clean carpets without leaving a wet-sheep smell behind. (presumably, a wet-sheep smell is not a good smell to have in your office.)

so does gary22 agree that HWE is always best? He has, after all, got all three, but chooses to use a LM system on office carpets.

Mike Halliday seems to be suggesting that it's the operator at fault if there's a wet-sheep smell left behind after an HWE job.

Sorry, but I'm getting mega confused here.

[Colin Day]

"Wet sheep smell" is associated with wool rich carpet.... Surely!

And, where did Mike mention the wet sheep smell

[derek west]

sorry i thought you were asking about cleaning a small piece of carpet,
the best method for cleaning a sheep is strap it to the roof of your car and go through the car wash, surely. 

[Seymour Sunshine]

And, where did Mike mention the wet sheep smell

 it wasn't the method that caused the problem (= wet sheep smell) but the operator

[Craigp]

Low profile carpet found in offices responds better to bonnet cleaning.

Mike was referring to residues. (read the post above his)

Wet sheep smell is wool as Colin says.

God your getting me confused
