Sheri I still wouldn't want a beginner to try wet cleaning the first time without at least someone who knows how to do it properly show her. Yes Eclipse is the way to go. If a pro tried cleaning your sensor with an Artic Butterfly then they weren't very professional. Most people don't even know how to properly use one. It is not meant to touch the sensor but to operate above it. And it won't work on stuff stuck to the sensor.
