The good thing about those plugs in champion X and A25 are resistant to heat and big enough you can clean the tips with a propane or MAPP gas torch if you're careful.

Don't rub them with a wire brush though. I've done that & the metal particles stay embedded a long time.

What about using a rag or paper towel? I have never cleaned a plug with a torch. Do you just stick the flame down in the plug end?

Thank you,
