Cleaning my corrector plate

When my secondary mirror holder came loose (when I attached the hyperstar lens), I ended up with a few finger prints on my corrector plate :-(

Of course, blowing some air or using a soft brush won't work here, so I worked on the solution from the Arkansas Sky Observatory:
I ended up being lazy and bought everything from Amazon (plus, some of the items were "Add-On" items, i.e. they only get shipped with orders of $25+).

After I received all the ingredients, I mixed the two solutions together. And then followed the instructions carefully - they were super helpful!


Looks pretty good. And breathing on it doesn't show any streaks!
