Fingerprints/debris on Diodes?

[ScubaSnyder]

Maybe I am just crazy but I have noticed with many of my lights... That the led dome/acrylic or whatever you want to call it has debris or finger prints on them, this could have been simply prevented by wiping it off with and anti-static towel...Just some thoughts.

Now that I have mentioned this you will look, and probably find things but, if you wanted to clean the emitter you would probably void your warranty:devil:
