i need one more thing how do i test it and how do i tell which ones best..like which one gets it out faster?

Answer 1

This would be an experiemnt in solubility. It would depend on the type of marker. For example a dry erase marker would come off without any solvent; a water base marker would come off with water; a "permanent" marker would require different solvents depending on whether it's an instant dry type or a paint type. You'd tell which one is best by which one works fastest, as well as which one removes the mark completely, without any traces.

Answer 2

try lemon juice, and anything citric...

or use baking soda-water mix...

milk wont work as good..

water and vinegar are the best out of the ones you suggested...
