Enock, it all depends on where the coffee entered the camera. I strongly suggest that you do no longer try to turn it on, and remove all batteries as well. You may just have to start thinking about disassembling the camera and to clean all parts with 90%+ isopropyl alcohol. The longer you wait, the more corrosion you may encounter. Use a soft brush to clean all cable end and connectors. It is a big job for a big camera. Go to [http://www.ifixit.com/Device/Canon_EOS_60D|this page] and scroll all the way down to the heading Service Documents and click on the blue link. That will download the service manual for your camera. Not an easy job, but definitely worth doing. Hope this helps, good luck.
