anyone used chem dip to clean the deposits on oem O2 sensor or wideband?

its been working pretty good so far on everything i put inside comes out cleaner...

Those sensors are so absolutely sensitive to chemicals it's best not even to try. You can get them fairly cheap at rockauto with a coupon code.

Cleaning them is futile, just replace them.

If you are really in a pinch, I have be able to reclock them with a margin of success.

what you mean reclock?

im kinda in a pinch i was tryin to take it to emissions again thinking problem was fixed and i know boschshchs sensor is worthless i already tried one before

so i tried 2 denso used sensors and both throw heater element code.
so i was thinking maybe to just clean it up since chem dip worked wonders on the block and head and everything else i put in it.
including spark plugs. cleaned them up really well

If it's throwing a code for the heater element after two then there has to be a wiring or connector issue. Cleaning them up isn't going to fix the heater element code and I'm not sure about WA but normally any code popup is going to fail your emissions test. Obviously simply cleaning them isn't going to fix the heater element code.

Test all 4 pins for continuity back to the ecu connectors from the oxygen sensor connector at their respective locations and see which one is the faulty one.

The O2 Sensor gets blasted by exhaust from one side primarily. I have on a few occaisions, removed the sensor, replaced the crush ring, and indexed the front of the sensor. I then install the sensor until the front mark is on the back side. Had fairly good results with it.

I should restate, cleaning or applying any chemical to the sensor head will most likely damage the element.

I suppose you could use distilled water which has nothing but water in it. But you're kinda defeating the purpose of an oxygen sensor by applying anything that has a chemical in it.

sounds like you have a wiring issue if 2 sensors throw the same code.
