Quick Question - Cleaning O2 Sensor?

I pulled the O2 sensor right in front of the cat on my exhaust. I have been getting terrible mileage ever since I seafomed and have already pulled the plugs and cleaned them (extremely fouled). I am hoping that cleaning this sensor might help. Anyone know if this sensor is "cleanable"?? - Sorry for the bad phone pic....

You can try some sensor safe carb cleaner but most of the time you just have to replace it.
You might just go and replace the plugs too unless they were new or close to it.

Thanks. The plugs were pretty new - about 16000 miles. I am ordering the URD kit in a couple weeks anyways and will probably wait till then as it comes with new plugs. I have some electronics parts cleaner that I used on my MAF and will try that. THanks for the help!

Seafoam is supposed to be O2 sensor safe. I think I remember reading one of the other guys just dipping the sensor in the Seafoam and wiping off the excess...
