If you do high end work I think the idea of showing you are woolsafe is a definate plus point, you will learn stuff like steve says BUT.. I wouldn't bother.
What are they telling you? Wool is a sheeps hair and you need to treat it softly, use only our products and you can sleep sound at night.
The reality is, in the real world, half the sheep carpets you will clean are shagged and you will be there all day and still have a poo result if you stay 'woolsafe'
Also when they endorsed certain Vanish products they lost all credibility in my eyes.
Woolsafe is a nice idea though whoever came up with it.

Best thing to do is get carpet samples a DO YOUR OWN tests long term. And use common sense, ie theres no need to use caustic on a nearly new wool berber. :
