Since we've been home, we've had a rash of our ball-tip pens stopping working. Most of the blue biros that we've been working our way through, ALL my gel pens have died, and my favourite white Signa marker is the latest casualty. They all have plenty of ink, but it just won't come out of the tip.
Has anyone ever had any success with getting them working again?
Sometimes warming them up will help. I've had success with using a lighter to warm the tip, but you have to be very careful not to melt the rest of the pen. If you don't want to risk the lighter, you could try (I'm serious) sitting on them. There are some pens, though, that are gone for good if the ink has dried beyond revival. Good luck. I know how frustrating that is.
