Cleaning o2 (wideband in this case) sensors?

I've been troubleshooting problems with my aunt's 2000 Volvo S70 (2.4L turbo). I just replaced the MAF sensor last week. The latest code is a P0133 which is slow O2 sensor feedback. So, I look up what the price is of a new O2 sensor. I guess Volvo went and used a Bosch wideband o2 sensor on this car. So, the replacement is almost $200 from the parts store. I'd like to avoid this.

My question is, is there any way to clean the sensor?

Maybe you could try one of those air-sparkplug cleaners with sand in it, effectively sandblasting it. My father's got one of those - pretty handy. If you don't have access to one you could ship the sensor to me and I'd put it in there for you. There's a nice junkyard here, but not many volvos :-/ Maybe Christ can hook you up - I think he's got 2 yards near him.

As a side not we passed a sizable volvo-only yard on the green grand prix economy run, but it seemed to be only older models.

I doubt it's the same but it's worth a shot. I believe for the last few years Audi has been using Bosch widebands (5 wire) for their O2's as well. From what I remember they were ~65 bucks. I'm pretty sure the Innovate Motorsports WBO2 units use a Bosch as well. Maybe that's a cheaper option for you if it's the same?
