Find out what colour your carpet really is...
... get in there with a proper carpet cleaner. And it also works on upholstery.
What you get:
The carpet cleaner and attachments
Two cleaning tablets free - you pay 50p for each extra so we'll have to calculate with you the approximate area and degree of dirt.
The instruction manual and a helpful note from a previous user.
What you'll need:
Access to an electric supply and a water supply. The cleaner heats the water and slows and sucks. Then you need somewhere to responsibly pour away the scummy waste water.
Other things you might want:
We have a couple of vacuum cleaners but also two pressure washers if you're in the mood for cleaning.
