I read through the points type testing, great write up but the typical capacitance values are too low, it should read about 0.2 microF on small engines.
For cleaning & polishing, just use an oiled strip of 400 grit "wet or dry" sandpaper glued to a wooden popsicle stick, followed by a shot of contact or brake cleaner. Works good for industrial motor starters contacts too, if they're not silver plated.
