HOW to Clean O2 Sensors [For FREE]

[@atxjax1]

A+ for effort and clear video. Placebo effect though.............cold water isn't going to clean carbon deposits.

[@ryansolomon5083]

A 50-50 mix of concentrated Simple Green and water. If you soak carboned up pistons in it they come out looking new in about 30 minutes. I just did this for 8 pistons for my 350 Chevy rebuild. Still had to clean the ring lands, but it even made that easier.

[@harinkarim3915]

Best way I found out is leave it in 1/4 of hot boiling water for few minutes also don't forget to spray some kitchen cleaning products to the sensor that will help to loosen the junk inside then stirring the sensor in the hot water every 10 to 20 seconds then u will see how much craps comes out with out damaging the sensor ,then keep changing the water till there is no more junks comes out after that dry it with heat gun or just hair dryer should work then see the results

[@paulsmith.3706]

Wow seems very intresting i never tried cleaning sensors before i just replaced them whenever they goes bad.

If you're cleaning the sensor as part of your maintenance great but if you're doing it because your having a problem with your sensor? Before attempting to clean it, test it with a multimeter to make sure it's not faulty. No point in cleaning a failing sensor.

@@JustAHevel he’s right. Gasoline has carbon cleaning detergents in it. Techron and other brands are formulated to remove carbon build up. Soaking them in gasoline will work, however there are less stinking alternatives, such as throttle body cleaner which, just like gasoline will vaporize quickly but without leaving residue behind. B12 (the fuel additive, not the vitamin) in the pour bottle, not the aerosol bottle, offers the least mess. You’re able to soak it in there and it’ll dissipate all of the carbon.

[@dandiy4958]

You can test this method by soaking an exhaust valve with carbon buildup in water and see what happens to the carbon, Nothing! carbon is a deposit from unburned hydrocarbons, it is not water soluble. Heat is the only way to clean and the cat converter is not running hot enough to burn off the carbon. In the lab we tested the functionality at 1100ºC for durability. Water is not the way to go.

Ultrasonic cleaners are used in many industries. I've used them to clean up jet engine igniters in the aviation world as long as the engine manufacturer specifications has a call-out stating that it is permitted to use them as an acceptable method of cleaning. As long as no moisture is allowed to get into the electric internals, ultrasonic cleaners are an effective, inexpensive method for extending the service life of certain components.

Spraying any sort of chemical on O2 sensors to "clean them" is a total waste of time and effort. NO chemical will remove the deposits that are inside the little holes. The problem is the other hard deposits inside the little holes, NOT the soft carbon on the outside! BEST way to clean O2 sensors is to heat the hell out of the tip that is inside the exhaust pipe to a bright/cherry red color. That is about 900F to 1000F. This will burn off most all of the deposits and the sensor will work again about 80% of the time. I have been doing this for many years. Works great and really is almost free to do. Just be very careful not to burn the wires or yourself!
