Just been to see this, and found out its a fabric called Novalife from Harveys. Looked on tinternet and only found one reference to cleaning this going back to 2007. Has anyone done these recently (suite is 4 years old) All the cushions are sewn in so couldn't do much of a test apart from on the back underside out of sight. this cleaned ok, soil transfered to towel by just using water but this was a clean bit so guessing its just dust.
