Thanks Marc. I found this site a few years ago and bought some products for the wet cleaning method here:
http://www.copperhillimages.com/index.phpIt's cheap and effective to wet clean. I use pec pads, methanol and the swab that he designed. It seems to work well. I think the website you posted does similar thing.
Cheers
Alex
P.s. I do not wet clean that often.
