Re: Cleaning O2 Sensors
Your diligence is admirable, but they're not made to be removed and cleaned. And because they are threaded into that hot exhaust pipe for all these years, they'll be very difficult to remove, you'll likely break one and have to buy a new one anyways. So just keep away and trust that they are good...or at least good enough.
If your car is 1996 or newer (earlier with some exceptions), your OBD-II diagnostic sytem will alert you when one has gone bad or when your engine is not running at optimum efficiency to minimize pollutants.
Other vehicles earlier than 1996 down to ~1987 have OBD-I to some degree which isn't as all-encompassing but still monitors the O2 sensor(s) for proper engine fuel economy. It will alert you to a fault as well by illuminating the "check engine" light. Check your owner's manual for it's operation.
