Well, one theory is that the chemicals contained in the whiteboard marker somehow reacts to the permanent marker, making it rub off, but it is not an excellent way to clean off permanent marker.
I don't know if this will work on piano keys, but dry erase markers erase permanent marker on white boards. Write over the mark, then erase the dry erase. If the dry erase doesn't come off the piano keys easily, use alcohol.
color dry erase marker over it and then throw it in the washer
try nail polish remover. hope that helps :)

You can actually color over it with a dry erase marker and wipe it off. I was skeptical at first too but try it it works.
you can only erase marker on a whiteboard but there is pens that can be erased From Charlie the Unicorn
Write with it and let it dry...it's permanent.
If by "wet erase" markers you mean water-soluble markers, the answer is - usually yes. The surface preparation for dry erase boards (whiteboards) is different from the way you would prepare a surface for water-soluble markers. As a consequence, it is not uncommon for water soluble markers to leave a stain on a whiteboard that requires some other solvent to remove. If a wet permanent marker is used on a dry erase board, it can sometimes be removed with an appropriate solvent, but often the whiteboard will be permanently stained (which you might expect from a permanent marker)
Permanent if you want it to be that. OR Whiteboard Washable
bleach or hard scrubbing um, try this, put dry erase marker on top of the permanent marker and erase it with a tissue

Whiteboard is one word when you are referring to the board you write on with dry erase marker, but I think it is two separate words when you are describing something else that is a board that is the color of white, but not the whiteboard you see in school.

it is tasteless
If its on skin wash with soap water and hand sanitizer for a couple of days if on white board keep washing with the spray bottle for the ones that aren't for dry erase i dont know what its called
try nail polish remover. hope that helps :)
You would be surprised. I was messing around with my diecast model buses and I discovered because at first I was using a wash cloth and water and it wasn't getting me anywhere so I thought to myself if I use a dry erase marker over the permanent marker it might work because when you have marker on a board and it wont come off, you scribble on it with a dry erase and then erase so I did that with my buses and it worked! try it out.
