you can't really. it is permanent and only comes off when your skin cells fall off. you can try ribbing the skin cells off, but it is hard to do If you marked on a formica or other surface, often wiping it with rubbing alcohol will remove it.
You can get sharpie off of anything by tracing wherever the sharpie mark is with an expo marker.
a black permanent marker by the brand sharpie that produce the best permanent markers in the world
Spray it with aerosol hair spray, not the pump kind. This will remove permanent marker or ink from almost anything. If that does not work, and it is a plastic surface that you would be able to wipe dry erase marker off of, you can write over the sharpie with the dry erase marker, and it will usually wipe off both the dry erase marker and the permanent marker.
It is very risking due to the amount of fumes from the alcohol. I recommend nobody should get high from a sharpie marker.
Axe spray you spray it on and wipe away your sharpie
I remove Sharpie marks by taking the Sharpie and a piece of dry cloth or dry paper toweling and apply the marked surface in small increments with the marker and wipe away before the marker dries again. In small increments works best and it will totally remove the marker from most surfaces that are not porous.
get a wipe and scrub it off
You can scrub it off with a tooth brush and Tooth paste.
you SNIF THE TIP OF THE MARKER DIP shiz niz
Acetone based nail polish remover. Honestly!!!
It should either wipe off easily because it is dry erase marker or they make a special cleaner for that OR the marker should just wipe off as people use it - thelightingtheifjw
A Sharpie permanent marker is not water based. It is alcohol based and it is waterproof.
