They endorse vanish but deny that this product causes bleaching of carpets, strange that because even in my limited amount of time carpet cleaning, about four years now i have seen dozens of those little white marks appear usually on natural berbers when you ask the customer what they used, out comes the bottle of vanish every time, we all know it does this we see it all the time, but the people that make it have deep pockets and woolsafe approved helps sales and helps woolsafe, everyone's happy except the customer with white patches all over that nicely cleaned carpet.
And for that reason "i'm out" they have no credibilty, and that's not even taking into consideration they endorse "Rugdoctor" again they have money and that's what counts.
To be honest i am disappointed by the NCCA too when the BBC did rogue traders on carpet cleaners the NCCA were no where to be seen as an authoritative source.
