Rapid plug failure in Chummy

[Ruairidh Dunford]

I have successfully on many occasions cleaned plugs in such a condition with brake cleaner and then blasting the insulator with a very fine media. Not always 100% successful but this method works for me most of the time.

I will give this a go, Ian, I had only tried cleaner and wire wheeling them previously and without success.

Also, I’d read that they could not be recovered, so did not attempt further methods.

Thank you.
