David, This is an ever present help in time of trouble. Don't do it. (grin) Cleaning mating surfaces will help pass a test. But it is a bad idea. The purpose of a test is to catch what fails. If there's a nonconductive film preventing contact -- and this is common! -- then you need to change the process that put it there. Or find another way to make contact in that location. You want your PRODUCTS to pass, not just your test samples. It is a great troubleshooting, tool, however. I favor a paper towel with alcohol; the silicates in the paper are rough enough, usually, and the alcohol will dissolve some of the grease.
