I've not had the need to clean the sensor on any of my DSLRs before, but for some reason dust has got in and I need to clean them.

I took advice from my local pro store (The Flash Centre) and purchased a VisibleDust Arctic Butterfly SL700, I have to say this thing is the biggest waste of money and all it has done is smear the sensor rather than clean it.

I'm just wondering what other people use, any recommendations???

Cheers

Cris.
