I've seen a few posts lately about people washing and drying oil filter and and checking from metal. How exactly do you wash and dry an oil filter?

I suspect that you are referring to the process used to cut open and inspect an oil filter's internal filtering media as part of an oil change. Remove the used oil filter, cut it open using an appropriate tool, remove and inspect the internal filtering media and then rinse the media's contents into a clean white container using gasoline or a suitable solvent. A magnet can be used to separate and detect any steel particles. Crushable black carbon deposits (aka "coffee grounds") are occasionally found. Engine manufacturers typically specify the amount and type of metal that is acceptable and how to proceed if metal is detected. The internet contains considerable information regarding this process and the metals that may be encountered.
Just noticed all three posts above are from Sonoma County CA, where flying is only good 12 months out of the year......
?.I put a zip lock bag over an inspection magnet, tight, so the particles do not stay on the magnet. This way I could get an accurate measurement of the particle ?pile?.....
Dang, what a good idea. I hate it when those little bits of carbon/metal get stuck down in the cracks of the magnet! Thank you!
