Discofilm is a gooey liquid with the viscosity of honey, used to clean the sensor of a digital SLR camera. Would you dare?
It is completely safe and effective, says its inventor Rainer HÃ¶nle. Many people have used it and he has presumably made a little pile of money selling it.
Discofilm is brushed onto the sensor (rather carefully), wait a couple of hours or so, and when itâ€™s completely dry you just peel it off and you have a very clean sensor.
Youâ€™re not actually brushing it onto the sensor according to Rainier. What you are really cleaning is the coated glass filter and not the real semiconductor, which lies beneath that glass filter.
He has posted complete instructions on how to apply Discofilm on his website, but if youâ€™d rather do a little practice, try it on a piece of photo filter first; its surface is pretty much the same as that piece of glass covering the image sensor.
