How to clean filters?

Recommended Posts

I have some Baader L/HaRGB filters and they look a bit scruffy, even though they're in a box when not in use, in the filter wheel. I have some Baader Planetarium Optical Wonder liquid. Can I use that with a lens cloth?

Also, I've used it to clean my ASI cam's sensor very successfully. Could I use it on my Atik's sensor if that's where dust has got in?

EDIT: there's this thread: http://ukastroimaging.co.uk/forums/index.php?topic=61597.0

Hi Alex,

The filters are quite hardy and I have used the wonder fluid and the baader micro cloth thing on mine as I am clumsy and fingerprint them each time I mess about with my filter wheel.
