Yes they are.
Most markers have alcohol-soluble pigment vehicles.
Blood is mostly water, and ethanol is entirely soluble in water.
soluble in water and ethanol
Have another go at writing the question.
Glucose is soluble in ethanol.
Chloroform is considerably soluble in ethanol.
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)

If you look at the scientific name for them (permanent markers) you'll notice that, by name, they're permanent; thus making them permanent. The fact that they are permanent is best shown by the fact that they are called "Permanent Markers."
Your best bet is to use alcohol. Permanent markers use alcohol soluble inks. Most white board cleaners have it as an ingredient.

Yes it is soluble.
yes, it is much more soluble in ethanol than in water.

Sand is not soluble in ethanol.
with water ethanol is soluble while methane is in soluble
