Discussion in 'Rug Cleaning Issues' started by Terry Miles, Oct 5, 2018.
Cellulostic browning only occurs in vegetable fibres and I doubt that there are any in that rug.
It appears that the discolouration is mainly at the base of the pile - that suggests up-wicking.
What John Says.
From the second pic the top part of the fibres are ok, so as John suggests up wicking from some crud at the base of the pile, could be anything. As it is Polyprop as you suggest and it looks that way, if you really need to go back as a matter of principle you could go a bit stronger on your spotter removal process. Try MPower spotter first if organic, but I would not own this problem if the rug as you say was a minger. You cannot be responsible for leaving a problem if it was there in the first place.
How did you rinse the rug, what tools & any intank solutions used?
Sometimes even after rinsing with a hand or stair tool these are better dried upside down with a blower underneath
