I used this again today and couldn't believe the response
Unbelievable
I used no4 wool safe on a 80-20 twist 60 oz, very spotty with sliver from dogs mouth but as it was a cream coloured carpet I was conscious of discolouration (i know who would have a dog and a cream carpet) but sprayed with no4 brushed in and then extracted with plain water and 1 very delighted client
All it needed was may be 2 passes and the carpet looked like brand new, also had very good response with coffee and red wine stains.
It is a very good product to carry on your van and it is a multi purpose chemical so you don't have to laden yourself up with tons of products I would highly recommend buying some it is not expensive!
