How to unblock a pencil-thin tip?
I like to use Fine Point pens, ultra metal, like the tip of the mark ONYX, but the metal tips clog easily, especially when writing on-a dried white Correction Fluid or other dirty surfaces. I had to shelve them after a doen only minimal use in the past year. I saved all of them, hoping to be able to uncover some day. They are something very big feathers. Does anyone know a good way to uncover? Thanks!
You might try using a penetrating oil like WD-40 and the air pressure for cleaning. You should clean good afterward.
