Not sure about the bait and switch issue - but at least goron got a serious response and a result. Anyway I may be opening a can of worms here but much more interesting I think is the issue of the Woolsafe 'approved' spotters, shampoos, cleaners etc like the list found in the booklet in the last link on this post - dont know if this is an upto date list but it seems to include some of the usual suspects for mis-use and of course we come across non-approved products (like Vanish apparently - which I thought at one time did have the woolsafe logo must have imagined that) and many of these that we come across on a daily basis - I am sure everyone has a story to tell about how they have seen diy products mis-applied or mis-used or however you want to describe the problem - sometimes the only reason people call you in is because they have a residual/re-soiling problem - so to some extent I suppose maybe we should be grateful that these products exist - I dont doubt that the Woolsafe procedure as outlined on their website is rigorous and it appears to cover all eventualities - it also has a telling line about "The re-soiling characteristics: cleaned carpets should not re-soil more quickly than the carpet did before cleaning." - this is under the section on Testing and Product Acceptability.
I would be interested if other people's experiences are the same as mine. More often than not (approved or not) the results are equally poor because the products are bought with the weekly shop and then just sprayed on the 'spot' 'stain' or 'dirty mark' and rubbed around a bit with no real thought as to what is going to happen next - now what happens next is not a lot as very seldom if at all does the customer think of how they are going to get the soils or staining material etc out of the carpet along with the product
(usually far too much of the product has been used) so we have maybe the released contaminant, excess product and the possibility of some damaged fibres where the carpet has been abraded or rubbed or whatever you want to call it - and although I am not saying the Woolsafe products would do this everyone will have seen the intense white spots that even when you have rinsed thoroughly look suspiciously like a bleach mark (caused by some form of sod percarbonate?) - plus also even if you 'only' have the over-applied 'shampoo' you may have a really fun time rinsing a serious quantity of foam out of the carpet and often having to add defoamer to your vacuum system - not the end of the world but to do a proper job and rinse this stuff out you are adding time to the job - and sometimes you can be pulling your hair out as you come across patch after patch of the dreaded white foamy junk...
and no doubt many of us have seen the worse case scenario where the stain/mark has not been removed, the carpet is damaged by rubbing and there is a bleach mark around the still visible stain - the unholy triumvirate of bad news - happy days
What interests me is whether Woolsafe decide to approve the products that they have approved or whether the egg comes before the chicken - do the manufacturers approach them for approval or t'other way round - also what does it cost (yeah like they are going to tell us that) to get that little woolsafe trademark on the label - I am sure consumers do recognise that logo and the dot org website is a subtle way of saying 'hey we are the good guys' above all the commercial hoi poloi.
have to say we are all I think susceptible to being lets say re-assured by the woolsafe mark - the two products I use most of at present are PureClean and Fibre and Fabric Rinse (latter leaves a nice 'hand' on wool carpets) and both have the woolsafe mark...
This is the booklet - interesting and useful(!) for consumers:
