a pencil eraser is a conductor .
Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.
Conductor
You can almost certainly get crayon out off upholstery with a Magic Eraser or some other solvent.
A magic one is an insulator.
Chalkboard erasers are made of felt. Felt is hair. Hair does not conduct electricity. Felt has lots of air entrained between the hair fibers so, it conducts heat poorly, too.
An eraser smells like the mixture of rubber and plastic.
In short, yes. The real question should be, isn't there a material that you can use that is superior to the conductivity of an eraser. <><><> Most chaklboard erasers are felt, which is NOT a conductor. When dry, a fairly good insulator.
Use Mr. Clean Magic Eraser.
The cast of Eraser - 2011 includes: Sarah Milici as Her Jerry Nash as Train Conductor
Mr. Clean Magic Eraser, it might take off some wall paint... you can find them at Walmart or Target.
It would be an insulator- chalk board erasers normally consist of two parts, a wooden handle and a soft pad that wipes off the chalk from the board. Neither of these parts are conductors of electricity.
