As I mentioned before on another post, my finderscope is a bit cloudy. I can see images through it but surrounding these things (moon, stars, Jupiter and so on), everything looks blurry. I don't think it is fogging up as I can see the centre image ok and can make out the centre cross (the wires).

I have pulled it apart (only the parts that can be unscrewed) and left it over night to dry out as I thought it may have some condensation. Hoping this would fix it as I don't want any thing growing. The finderscope is on a 10" collapsible dob.

Is there a way I can soak it in something like dishwashing liquid or hot soapy water and clean it and leave it to dry naturally?

Physically, I can't see anything else to cause this.
