- moylan 15y agoi use the graphite of pencils on door hinges. also the soft eraser on the end is quite good at cleaning contacts on motherboards from grease and the like. that and a non conducting pencil is handy for raising the guard on uk and irish power outlets to plug in 2 pin cables. just that i find it easier to carry a pencil in my toolkit than risk a possibly leaking container of wd40 near the rest of my electronics.
