Hi all,
I have some emission filters with dust that will not blow off, and one with 
an obvious fingerprint, all of which show up as blurry smutz in the image. 
I appreciate the need for caution when cleaning filters with soft coatings; 
e.g. no organic solvents, no touching, etc.  But what about a simple soak in 
dilute soap and water, followed by dH2O rinse?  Or, will a polymerizing 
cleaners, such as Photonic's First Contact work?  Obviously there is a 
solvent in this to keep the material liquid until applied.

Thanks,

c
