Just a thought,

Has anybody tried 'Pledge Clean & Dust Wipes'? We're not advertising for them but they do the job and you've no problem with overspray clogging up the electrics.

Any comments?

Made for the job are "Keywipes", available from BCK as either single wipes in pods or continuous wipes in a drum. They don't cost the earth and will not remove printed labels on your keyboard. Ask your dealer for them.
