Right, I saw that in your email post, which is why I thought you had already done all this.

A dry finger won't do, you need to have a moist finger and even that sometimes doesn't work, depends on the value of the pull up resistors.
Bottom line, metal contact is working, go with what works. I suggested aluminum tape because it's thin, has a very good self adhesive and is metal. Another option would be to use a dark pencil, like B2 or B4, test it first by darkening a dot on a paper and see if this paper can serve as the contactor. Grind a bunch of the lead, find a glue that sticks to the old contactor, dip it into this pencil lead powder.
These are just idea's, but they should work.
