I came across this a while back and thought y'all might like it.
How many of us use a graphite pencil when laying out a project? How many of us have gone .... OOPS! wrong spot for that line. How did you remove it? Sanding it off? Use up one of those huge pink erasers? There is a much simpler way. Today's pencils are made of graphite and the graphite is made into a paste that is extruded into the lead. This lead is most of the time easily dissolved with Denatured Alcohol. So wetting a rag with Denatured Alcohol and rubbing it on that errant pencil line will get rid of it without sanding or wasting an eraser. Most of us have Denatured Alcohol in the shop.
