Default Cleaning a wbo2 sensor

Hey guys, just putting my car back together and unfortunately i got the tip of my wbo2 sensor a little dirty. It looks like when it was dangling under the car it got a little bit of oil on it and some dirt stuck to that. Now i've blown it off pretty good with my air compressor, but it looks like just a little dirt is suck up in the tiny holes on the end.

Now my question is, should i attempt to clean this thing with carb cleaner, vinegar, or any of the other random solutions ive read online? I dont want to ---- up my expensive wbo2. It's an AEM if that matters. Anyways, what do you guys think?

Currently im leaning towards just screwing it in and using it, and cleaning it IF it gives strange readings and not worrying about it otherwise. Anyone ever clean a wb02 and get good results?

Thanks again gays,

No idea if it would harm it but possibly CRC Electronic Parts Cleaner? I've seen people use it to clean sensors before (never a WB02 specifically though).

Hose it with brake parts cleaner, then let it dry thoroughly. Then blast with blow torch for a second or two. This will remove any residual combustables that may interfer with the reading and blast off most of the loose carbon. I've done this probably a dozen times when my sensor starts to act up, and I've been using the same sensor for going on 4 years now.

Thanks, baron! Thats the kind of answer I was looking for.

Bikersam, I actually read about people using the Electric motor cleaner on it before, but that was in specific to NBo2 in the thread I read at least. I'm still thinking I might do nothing at all, and then try Baron's method if its acting up when i reinstall it. Thinking about it I'm sure most the dirt/oil smudge will get blown out/burnt off pretty quickly in boost.
