I just used Dryton for the first time and on recommendation of a neighbour.
My carpets are a light colour ,15 years old, had not been cleaned for 5 years and in the living room had many stains, some years old which had not been removed by other contractors.
The living room carpet I was thinking of replacing, but now it really does look like new.
I also had my drapes cleaned.
Not cheap, but a brilliant job. It was certainly value for money by a professional operator.

Approximate cost: $900.
