So, I live in Louisiana, and it can get quite humid even indoors, especially in the winter when its still quite wet but too cold to run the A/C. Anything steel rusts rather quickly, and so I go pretty liberal with the CLP when I clean my AR-15.
A few hours ago, I was handling this AR-15. The gun isn't drenched in the stuff, but theres apparently enough lingering around that when I touched a CD (by the edge, of course), it damaged it. You know how when you touch a CD sometimes the water vapor from your skin will leave foggy marks near where your fingers were? Well, thats how it was, except the one mark wouldn't go away.
And of course it was a data CD, and part of one of the files could no longer be read by my drive.
After extensive cleaning with a three-stage CD cleaner kit from Phillips, I was able to get the computer to read the CD again (but very slowly).
Moral: If you put more than a very light amount (desert style) of CLP on your rifle, do not touch any sort of plastic at the same time you are handling your rifle.
