45 bottles worth of cleaning - I got this delivered at the weekend. Should be priced up at £14.99 (the twin pack of it is £40!!) it's a bathroom cleaner, fabric cleaner, kitchen de-greaser, general purpose cleaner and a glass cleaner. When the bottle is empty, you press the button to release a dose of concentrate then fill with water. You get 9 doses per bottle. Just in time for the spring clean!!!! There is also a video demonstration of it on their website. Hope that helps someone wanting a sparking clean apartment.
