Okay then Matt, here goes. Let's see if it works (I bet not) but here are the before and after.
This first picture is what we inherited on the kitchen floor, and how it had remained for six months (because i'm a lazy **** sometimes, and I couldn't be bothered to clean it until it was absolutely necessary). The letting agents swore to me that this carpet had been professionally cleaned, and that there was no way it would come up any better, as their cleaner had tried everything possible.

Now here's the result after using Solutions no. 3 spotter and before I gave it an all over general clean with no. 2 when it really came up brilliant, except, er, for that whacking great indentation by the cooker. But I'm using that finished job pic as a publicity shot, so I'm keeping it a secret.


Right, I've modified the links. This board obviously doesn't like pics being linked to thumbnails. The guy who first showed us around when we moved in couldn't believe it when he saw the carpet on our departure inspection.
Oh, and as for chewing gum, I believe it's called no. 6 although I've not had a need to use it yet.
