Are the contacts in our LBCs plated? I thought they were solid metal (not
sure WHICH metal, o' course...)
How does microscrub work? Is it an abrasive or a chemical? (or both?)

I guess I'll have to add an addendum::
-Use only v. fine sandpaper (600+) unless the contact is very corroded
-Afterwards apply a dielectric grease (maybe just Vaseline...?) to stop
repeat offences
My turn signal switch was badly gummed up with corrosion. I used a
rougher sandpaper to get them to work. I am going to polish them up
properly now that the column is out of the car.
