Step 4: Cleaning

Picture of Cleaning
To clean the contacts, the best tool I found was a pencil eraser. (Unfortunately, I used up three erasers in the course of this project) Just rub the spring and runners until they look roughly shiny again, and be sure to blow away the eraser crumbs.

the best kind of erasers are grey and stiff, and sometimes have a lil grit to them, they may be ink erasers. my father used one for cleaning his H.O. train rails when i was younger, and i used the same exact eraser to clean my Tyco slot cars & tracks they last quite a bit longer than the pinkies.
