Hey all, just curious as to how/if you guys have ever cleaned an oxy sensor. I was just reading another post where BoostnBass said stick it in a lemon overnight, so that idea got me started thinking. I know theyr'e quite delicate, but there must be ways to clean them up, new ones are $150+!!! cheers

I read that exact post about 2 hrs ago when i was searching for stuff on dual stage boost controllers... and it also got me thinking!!!!!

You mean Literarily Stick it in a lemon??? What'll they think of next! Some original photos have not been recovered yet.

That's the idea i got, i thought maybe i misread it the first time, and it meant lemon juice, but it had no mention of juice, just a lemon!

There are lots of ways of cleaning them, but they never return to new and have good response. you need to apply 12volts to the heater element whilst its in the lemon, lol

yeah i'd say the acid in the lemon is enough to slowly clean them out but not strong enough to damage them, hehe. Anyone have any definite methods to freshen them up a bit? so far ive heard of 1) the lemon method 2) blowing the junk off with an oxy torch

thats what i said !! how the f##k would a leomon clean it!! and old mate said stick it in the lemon leave it for a day wash it in water and stick it back in !!worked for me !! car runs like a dream

bosstn, have you checked your mixture LED's now that the sensor has been 'lemoned'?? Are they showing good mixture?? (sorry if you don't know what i'm talking about!) Some original photos have not been recovered yet.

I use the CRC carby cleaner the type thats safe for oxy's and cat's. Just spray some into a container to cover the oxy sensor and leave it overnight.

have heard wd40 is good...

how about gasket stripper? that stuff takes carbon off very effectively.... then spary that off with some wd40.

You guys are nuts!

strap it on to a lemon and apply 12 volts suspect this definately wont clean it

ok i cover the thing with carby cleaner and leave overnight, do i wipe it down the next day or just put it in???

i just soaked an old one in WD40 over night then washed it in water then dried it out. havnt tested it yet tho

WD40 cleans off with water, thats news to me!

I know it sounds funny, but 2 dyno operators I know have used this teqnique. WD40 etc will coat it in greasy sh1te, wouldnt do that. most people are guessing here (as usual) VLT O2 sensors are cheap enough, I have only heard of cleaning being done on $550 + sensors. Some original photos have not been recovered yet.

so let me get this straight. stick the o2 sensor in a lemon and apply 12 volts to the heater element and then leave it over night? Is this correct or just bull****?

this thread deserves a gold star Some original photos have not been recovered yet.

wanting to clean mine is this for real or what? stick in in lemon juice
