Contact Points

[otis71]

What are some recommendations on type and grit of abrasives to use or avoid cleaning magneto points or ignition points? I’ve been told so many contradictory answers I want to see what the consensus is here. Thanks.

I use a point file.

I retired 20 years ago, so I can't say if Plastones are still available. As an industrial electician we often used them for dressing elecrical contacts. They came in various widths, thickness and coarses. The were specifically designed for the purpose of cleaning electrical contacts and therefore they had no coductive particulate in them. They will not remove as much material as a file. They can also be used to dress contact points in voltage regulators.
