well i got out 95% of the green crayola marker lines. yellow shows it still a bit but not much. I'll see how it looks tomorrow when it's dry.
after soaking, i applied WD40 and liquid dishwasher soap, rubbed that in and washed with Oxy clean again. then next time around i sprayed the marks with Shout Advanced and washed with Oxy clean again.
looking so much better. tomorrow is another day.
