Ollie,if you do have a try with the Intemos stuff,be prepared to do clean the sensor twice.I do it once then take a few shots,check the photos,and then quite often have to clean a second time.It does work.So if you do order some swabs etc,make sure you order sufficient swabs,they must only be used ONCE.The first time I tried,I did re -use the cleaning swabs,a total disaster.
My hand joints are quite stiff,and I do find it difficult,but I can manage,so if I can do it then so can anyone else.I used to send off to Lehmanns,a very good company,highly recommended,but it is cheaper to do it yourself,esp after the warranty has expired.

Christine, the first (and only, so far) time I've used the Intemos kit I used an overly large drop (perhaps more) of fluid on the tool and found it impossible to mop it all up with the reverse side once I'd scrubbed the stubborn blob off. A repeat swabbing cleared up the mess and left me with a clean sensor.

I've not used this method as a primary cleaning method and I'm rather sceptical of my chances of successfully removing all of the liquid with a single tool (and at a couple of quid a shot and with me being as tight as a gnat's chuff....). However, as a backup for shifting stubborn marks it's excellent.

You're a bit hard on yourself there, I've seen you get out one of those big white fivers in the past. Unfortunately Victoria complained too much about the bright lights and you returned it to whence it came. :)
