Seems strange to me.
All this talk about M/S verses traditional chemicals and weather they damage your carpet, yet nobodys mentioned the damage risks to our health, most if not all M/S are labelled as non toxic, surely thats the main point, unless your going in wearing full head to toe protection with an air fed mask your breathing in and taking in through your skin whatever you choose to put down on the carpet, that's the selling point for ME.
