has anyone out there heard of the camraso report?


Independent test, carried out by 'CAMRASO', a British carpet research organisation have proven that 'In plant washing' removes 90% of soil particles, while 'Steam cleaning' removes 40%.
Similar evidence has been provided in work carried out by the 'International Wool Secretariat'. A number of 100% Wool Wilton carpets were laid on London Transport Silver Jubilee Buses, and soil levels as high as 2.5kg/m2 were recorded. After 'in plant' washing the level was reduced to 100g/m2, which represents a soil removal of 95%.

I have not heard of either report, but it sounds correct to me- and that is the larger amount of water used will remove a higher percent of the soils present.

If this was not the case, the many rug washing plants would steam clean them, or some other process, but a lot of water is hard to beat.

That said, cleaning wall to wall carpets which cannot be plant washed are best served by other means.

Thanks Gary, have you ever seen any sort of published study on in home cleaning vs in-plant washing?

Steve- not that I can recall.

I have been plant washing rugs since 1956, both for my own business, and I worked in several plants for other companies, so I have had a lot of experience doing this kind of work.

This said, I give you my opinion on this subject. Plants that have automatic washers, and wash say 50 to 100 rugs a day, every day, do not get the rugs any cleaner than doing them on location, or say bonneting, shampooing or steaming them.

But the plants that wash one at a time, by any manner with individual focus on the one rug, and deal with it until it is as clean as it can possibly come is far superior in the cleaning results than the other ways.

Why do I say this? Because, after an automatic rug washing machine, or steam cleaning, bonneting or shampooing, if that rug is gone over again with a clean bonnet, there is always more dirt removed.

(Or is this off topic?)

Gary

Thanks Gary.
What percentage of soil do you think is left behind after steam carpet cleaning or encapsulation cleaning?

steve

No single system can remove 100% of all the soils present in any carpet or rug, but most systems remove MOST of the soils present.

At a guess, I would put the following percentages with the following procedures, this is not scientific, but just my observations doing the various kinds of cleaning over the years.

This is assuming a qualified technician, who knows what they are doing, with a lot of experience, good chemicals and equipment. Not a beginner with their first trial.

This is MY opinion, if you disagree, that's fine, that's YOUR opinion.

Plant washing- 99%
TM steam- 98%
Bonneting- 97%
Shampooing- 97%
Encapping- 97%
Dry powders (which are NOT dry, SOME water is used)90%

Because ANY process leaves SOME soils, anybody can remove MORE soils by a second process of any kind.

This means the second process uses different mechanical agitation, and chemicals, and this is the basis that Kirby, Electrolux, Oreck and other vacuum cleaner manufacturers who use this pitch to claim THEIR vacuum will remove dirt yours won't because you vacuum your carpet with yours first, then go over the carpet again with THEIRS, and whaddya know- they DO get more dirt, and this proves that your vacuum cleaner is worthless, and you gotta buy a new vacuum cleaner from them at an exorbitant price, but it is worth it because yours is crap.

(It's a VERY old trick, old when I sold Kirby vacuums some 40 years back, and yep, I was impressed at the time too, just like anybody else was- and still is.)

Oh yeah- when I was selling Kirby vacs, many years ago, one of the first things I would do, if I was allowed to do, was vacuum the mattress. The amount of gunk removed from ANY mattress IS impressive to see.

Sometimes as much stuff is removed from a mattress is about the same as an equal area of carpet!!
