Would using a Q-tip with Windex really be that bad to use on the sensor for tough spots?
Well, it would save you a fortune on cleaning supplies, but might cost you in low pass filters. Many manufacturers only offer the low pass filter for replacement with a complete new sensor. I don't know how sensitive the coatings on the low pass filter are, but Eclipse recently released a new cleaning fluid that is supposed to be gentler on the new coatings manufacturers are using. So, given that the cost of a Q-tip is less than a penny, do you want to trust the quality control that went into making it? Here's an article on the sensor coatings:
While I use the Copperhill method, I do cut a corner. I don't use the swabs unless I'm traveling. At home, I take a PEC pad and cut it into eight strips, then wrap a strip around an old swab stick. You can get a pack of 50 PEC pads for about $12 or $15, so I squeeze about 400 cleanings out of that package. Even then, there are occasional issues with lint remaining on the sensor, but the blower deals with that.
