As we all know stains that have been tackled by a custy can then be set, I find this a lot with red wine and Vanish. I can normally remove wine if this has not been used. I emailed them to find out why and got this reply. Basicaly they deny knowledge of there product 'setting' the stain?
Thank you for your recent email regarding Vanish.
I was sorry to learn of your experience with Vanish.
Vanish has been designed to remove normal household stains. However, stain removal performance is influenced by many factors including stain type, age, intensity, fabric type, and previous treatments (i.e. use of other stain removal treatments).
Vanish is effective on a very wide range of stains but occasionally, repeat treatments may be necessary. Vanish Oxi Action has proven to be very successful in removing oxidizable stains, e.g. fruit juices, red wine, tea, coffee, water based ink, coke, grass and mud. These are accepted as some of the toughest household stains to remove.
Some stains such as permanent inks, some paints, rust may be impossible to remove.
We have had no reported cases of Vanish 'setting' stains into carpets. It may simply be that a repeat application was necessary and not performed.
Thank you for contacting us on this occasion.
Kind Regards
Vanish
Any ideas on a response to this?
