Just wondering how people clean the bottom side of inserts? Q-tip? I know that mine are pretty filthy. Lots of built up dirt. I figure if I'm going to do a cleaning then I might as well go full throttle.

air compressor, did a real good job for my andromeda...

I use Q-tips and Rubbing Alcohol

I dont like rubbing Alcohol, from the tests i did, it turns white when it dries...

I use QTips and Windex.. works perfectly and doesnt create any white layer when drying.

You can't use RUBBING Alcohol, it contains contaminents; you need to use a good quality 99% Isopropanyl Alcohol and a q-tip, it evaporates almost entirely clear.  But I find windex works suitably well for me too.  

Isopropanyl Alcohol, Distilled Water and a touch of Ivory liquid soap (the unscented clear kind) is what most lens and screen cleaners are made from.

Pure isopropyl will evaporate 100% within a few seconds. There is NO residue. And it is shocking how black the QTips can be.

Good to know.  The stuff I have been using is 70%.
