How to fix overfilling of A/C Freon

Thanks to a Idiot moment I had a while ago, my A/C freon was overfilled by at least one can. To fix this, I got some advice from several respected sources, including one mechanic who was nice enough to post a video on youtube. After the fear of messing with A/Cs was gone, i realized how easy it can be when you have the right tools and good knowledge.

Dont forget to clean up your mess. I used a water hose to rinse down the valve area.
