Cleaning the Bigma (Sigma 50-500mm)

I was quoted $225, sans shipping, by a Sigma service center to clean the lens elements in my Sigma 50-500mm lens. I decided not, and cleaned it myself. It involved the removal of six screws and... wait, that's it. Six screws out of the way, and the front element is removed, allowing you to clean out all the dust and debris that you decided you would just have to live with... Total time invested: 15 minutes. Difficulty scale 1-10: 1. Money saved: $220. (I had to buy a precision screw driver set... money well spent in my opinion!
