I have used Mpower sucessfully unlike others, I use RO water, maybe this makes a differance.
I too have just trialed Bioclean and could not tell the differance, it appears same as Mpower, same smell, colour and dilution rates.
I did a musty old axminster the other day, no wet wool smell afterwards and customer was very pleased.
Have to say that Bioclean is very good, just need to trial it on some puke !!
