carbon cleaner...........
I use a carbon cleaner Slip2000 carbon killer. You can buy from any gun or sporting good store. I use it to clean my weapons. Just remove the O2 sensors and soap them. Works for me.

I tried carb cleaner and also ultrasonic cleaning with water and either didn't recover the sensor.
I haven't tried the gun carbon cleaner but I bet that's the best way to do it. I have been looking for the gun cleaner to use in my ultrasonic, which would be the best of both worlds...only if that cleaner is not flammable.
I have a pair of brand new 02's that are working fine, if/when they fail I'll try the carbon cleaner trick. Good suggestion dieseldave!

I doubt much would save one, especially if they are contaminated with gasket sealer or antifreeze.
Here's an idea of what they are made of:

The only way you would know is on a scope or scanner to see the signal itself. "Generally" the O2 sensor get's LAZY over time, not responding quickly to O2 changes in the exhaust stream. I would guess the coating on it breaks down over time in the harsh environment it lives in.

What?
Who has gasket sealer and anti-sieze. I never use anti -sieze for that very reason of possible contamintion.
I've used carbon cleaner for years with great success. What is soot? carbon! Soak the element in Slip2000 over night. No damage.

BUT, does it actually help anything?

Yes, I think the question is not if the outside of the sensor becomes clean, but actually if the "lazy" or "non responsive" sensor actually starts working (oscillating) again. So far, if a sensor has been non responsive, I have been unable to get it responding again.

Of course.......
Of course the sensor has top be in working order. I was under the impression that this was maintenance. I periodically remove the carbon build up on my 02 sensors as I would carbon in my throttle body or clean the MAF. This soultion will not bring the 'dead' back to life.
