Can you clean an o2 sensor? Got a code and I know it's in front of a blocked CAT so I'm wondering if I change the CAT do I need a new o2 sensor or can I clean it? If so how?

Have a 96 EB Explorer 5.0 Got a code for bank 1 o2 sensor but I'm not sure which is bank 1 and which is bank 2? I would assume that being in front of the grill and looking into the engine bay Bank 1 would be on the right and bank 2 on the left? Correct?
