Thanks,

i use pecpads, eclipse solution and a cut down rubber spatula. honest.
never had any issues when doing this and leaves the 'sensor' squeaky clean afterwards.

having typed that lot, guess i'm gonna have to check it out when i get home
Yeah, I would check it out before applying simple physics to the equation..........then you can let us know your findings

i stand corrected. simple physics divvna work here.

that'll be me with the dunces hat stood in't corner then

could only get marks to show up at F22 - F32. anything less than that and they got blurred nicely to the point where they're not visible (even at F1....which is probs why i thought my sensor was clean - rarely shoot about F8, and usually it's 2.8 or 4
