Whiteboard marker swingin' around refreshing trick - GIF

[Drew1966]

Must try that with permanent markers as they dry before your eyes. one or 2 uses & $5 to $8 in the bin.

We used to flick ball point pens to loosen the dry ink within or refresh but never thought of that method.

Try also injecting a little Methanol, Ethanol or even M.E.K. with a hypodermic syringe right through the tip. Different solvents work for different brands. You can remove difficult marker stains with WD40.
