Default Can I CLEAN my O2 Sensor?

OK.. IM just about to sefoam my car in a few miutes, and I hear alot about how it fouls out O2 sensors. I wan wondering if maybe soaking the sensor in either alcohol/acetone would maybe clean it out... Or is it something a bit more serious than that. I dont feel like spending the $$$ on a new one because theyre quite expensive for my tastes.

I'm not sure if SOAKING an O2 Sensor in anything except AIR is a good thing...


but lets see what others say. Click the image to open in full size.

if this is the case then don't use seafoam on your car. i have heard good and bad things about this, and if your worried about a O2 sensor (which is probably the least thing you should worry about), then i don't recommend it! Click the image to open in full size.

Fouling out plugs/O2 sensor, as well as blowing headgaskets... most of which happen to HIGH mileage engines... mines only got 68000. I plan on using it ONLY through the BB vac line, and the rest into the gas tank. Im not gonna put any through the oil cap or crank case.

this is why i won't use it. there was a post a while back about this kid who claimed to have gained 10 extra horsepower by doing this. but the same day he posted (on another thread) why he was having problems with is engine after seafoaming.
IDK, call me old school, but if you change your oil every 3K or alittle earlier then there would be no problems.

What about misting water into the intake to clean things up instead of seafoaming?

actually wheter or not you change you oil on time, there will be build up/sludge in your motor. you just have to be smart about doing seafoam. you run it through your motor right before an oil change.

i seafoamed my car a couple weeks ago, then immediatly after changed my oil and oil filter and ive had no problems with my motor or 02 sensor and i have DEFFINETLY felt the difference seafoam makes. the car starts up way better, feels healthier and runs stronger so yes it does restore some lost horsepower and it makes a huge difference on your motor depending on how much actual sludge build up there is. and all this was on my 143,xxx d16 Click the image to open in full size.

Did you ever think of unscrewing the oxygen sensor from the header/exhaust while you seafoam it? It won't run great, but it'll run enough to get the job done.

Also, you can sandblast oxygen sensor tips to bring them back from the edge of shitty. I do it all the time. Good luck.

I'm not sure how many CFMs you can push with your mouth, but if it's enough to double as a sand-blaster you may want to look into pornography as a career choice Click the image to open in full size. Click the image to open in full size.

Honestly though, some 800grit sandpaper and compressed air is good enough to get most of the large debris and gunk out of the sensor. You won't be as thorough as a sandblaster, but you'll be maybe 75%.
