Without wanting to start a whole pro/anti debate about using antiseize on spark plugs…
I put the new plugs into my engine today, and by chance I got a small blob of antiseize on the porcelain “tower” that the electrode is mounted on. I wiped it off, but the previously pure-white porcelain is now a slight grey colour. The actual electrode is clean.
Should I junk that plug, or am I overthinking it?

Overthinking, if you think you have a bit left, bit of brakecleaner and rag/towel, done; be fine. Should only be on the threads. Necessity IMO for some engines (like mine) with 2 piece design plugs that snap with carbon buildup.
I’d throw that plug away. To much of a chance for a short there causing a miss. Fix problems before they start.

Hit it with some brake clean and reinstall it.
Well antiseize usually contains either copper or aluminum, both good conductors. If the porcelain is porous you aren’t going to get it all off. So, you foul a plug and burn out a cat. This for the price of a plug.

True enough, I still don’t consider it a toss though unless it’s left on or really rubbed in, the amount that would make it into the porcelain would normally be negligible. But yeah, if it’s any real concern to the OP, chuck, spend another $4, and not worry about it again.
