New Bosch oxygen sensor tip got dirty-- how to clean?

[DaveInLA]

My uncle just bought a Bosch O2 sensor for his E30 eta engine, but when it came in the mail, the plastic cap got loose and some of the anti-seize compound smeared on the tip. I know how important it is to keep that tip clean, and he's unsure of how to get the stuff off. Should he just wipe it off with a paper towel, or maybe use alcohol or WD40? Thanks.

I'd use brake cleaner, as it doesn't leave a residue.
Hose it down good and hard, and it should be just fine.
BTW, don't forget to put a little anti-seize on the threads!

I had this happen before.

I wiped it with a paper towel--that got all of it off.

If it hadn't, my next step would then be to use a paper towel with brake part cleaner on it to wipe it again.

Just clean it with whatever cleaner you have. Antiseize will burn off anyway.

lintfree cloth.

Do not spray any cleaners on it. Just wipe it off and it will be fine.

If it's only on the metal protective shield, then yes, simply wiping it off is good.
