It seems that Sharpie pens have a very short life.  I buy one and the next time I try to use it, it is dry.  I read another Instructable on rejuvenating the big fat colored Sharpies using acetone and decided to try it on the one pictured.

What I did was just make a quick dip into the acetone and remove it.  It worked.  I was able to finish the project I was using the Sharpie on.  I don't know how long it will last, but it saved me a trip to store today and that is good enough.  Finger nail polish remover containing acetone should work also.  I hope this helps someone else.

I like projects that cost $0.00   :-)

4/7/14 Edit:   I tried Petrucci's method of refilling Sharpies with hypodermic of 2ML of acetone.  I injected it at the rear through the plastic case.  I pushed it through with syringe empty, pulled it out and filled it with the 2ML acetone and then injected it.   

It takes quiet a bit of pressure to push the needle through the plastic, so there is a danger of bending or breaking it. I found the needle penetrated better if you turn it while applying pressure.  I plugged the hole with Dap silicone calk when I finished.

The injected pens are working as good as new or better than new.  This has been a great experiment, and with the help of 
Petrucci, it has been very successful.  
<p>Just pull the nib off with tweezers- </p>
<p>I'm chemist so i use permanent markers a lot - they can be refilled with acetone and they last until the pigment ends, 10x longer or more. If i can't open the body i just take a syringe with a thin needle and inject right through the marker's tip about 2-3ml of acetone and let it stay overnight vertically(closed) to let the pigment dissolve and flow to the tip.</p><p>Acetone refilled marker writes better on wet surfaces, unlike the original toluene solvent does.</p><p>Methanol works nice too.</p>
<p>thanks for the comment, pertucci. I will try your suggestion. I suggest everyone try it and let us know. Mine was a short time solution. </p>
<p>The sharpie I dipped dried out in one day. After injecting 2 dead markers &amp; waiting 6 hrs they both wrote great. Perhaps a combination of both methods would make them mark immediately and work for a long time. Thanks again Petrucci</p>
<p>You dip the tip in acetone? or you remove the cylinder cartridge and soak in acetone? I'm a Sharpie fan, so it's good to know!</p>
<p>Gabeuse, I just dipped the tip into the acetone for about one second. the cartridge is only about 1/2 to 3/4 inch long, so I don't think soaking it would do much except wash all the ink out of the cartridge. </p>
