Cleaning Oxygen Sensor and MAF Sensor

[silverGPX]

Just wondering I was looking at cleaning the Oxygen Sensor and MAF Sensor in kate's GR.
Ive looked through a few things in google.

With the Oxygen Sensor, some sites say leave it in a bottle of fuel overnight, some say clean it with electronic cleaner.On a commodore forum they reckon plug the heater wire in and push it into a lemon overnight <---- LOL(TYPICAL OF COMMODORE OWNER)

And with the MAF sensor most recommended a electronic cleaner that doesn't leave a residue.

What do you guys think of this? Has anyone cleaned theirs before?

dont be a tight arse and replace o2 sensor as for MAD never cleaned mine or would just use contact cleaner etc

To clean the MAF, just run a rag damped with metho down the front of the central pickup sensor. For the 02 sensor, second the above ^

I've still got my old oxy if ya want it. Changing my sensor did stuff all.
