NW Iowa | Get one of those little one quart sand blasters, put baking soda in it and blast into the socket. The soda shines things up but doesn't do damage. If I am right the real soda blaster people use a different kind of soda but plain old baking soda is readily available for the small job you are doing. Wear a breathing mask, that soda that will get on your lips will taste funny. Blow it out with air and spray whatever contact stuff you like into the socket. | |
