Please tell me how to clean a car's oxygen censor without removing it.

Typically you won't clean an oxygen sensor on a car. Replacing these sensors is meant to be cheap and easy. So, typically they are conveniently placed and stocked at Napa.

you can try a fuel additive that you put in the tank of the car. This unlikely to do you much good if the sensor is bad. The other thing that works is to take the car out and drive it hard with a lot of open throttle. Otherwise the only other option is to replace the sensor.

Short of taking the cars manifold or pipe off then there isn't much you can really do to clean it. Using a higher grade gas will help to lessen deposits but it won't clean it.
