Perhaps so, but you're degrading the integrity of the contact. When using steel wool, you are putting microscratches on the surface of the conductor. This will reduce the number of points where the two metal surfaces meet thereby reducing the conductance. Likewise, when you use an eraser head, you are inadvertently leaving a thin trail of insulating rubber on the surface of the contact which will also reduce the overall conductance.

Come on guys... a bottle of Brasso is only \$3... that's not exactly going to break your bank. And how often do you normally use Brasso? I remember my parents had the same 8 oz bottle from the time I was four until they finally threw it away when I was in highschool. I also remember watching the Price is Right as a kid and seeing the runners-up winners win lifetime supplies of the stuff... a whopping five bottles.

not everyone has a supply of the stuff laying around the house tho

and for a quick fix eraser heads do the job, hopefully everyone has a pencil
