“I recently built my daughter a book case with maple plywood. I made a homemade pegboard jig for drilling the shelf support hole. On this jig, I used blue chalk to mark the holes for drilling. Some of the chalk got on the maple. I brushed it away. Most of the chalk was brushed off. Some chalk remained.
I did not worry about it at the time. I thought I could get it off later by lightly sanding or washing it off with a damp rag. Big mistake. Sanding did not work. Sanding too much and I would blow through the top layer. I tried spraying with bleach and a card scraper and probably a few other things that I can’t remember now.
Is there something else I could have done?”

I suspect a solvent, like denatured alcohol, would have been a better wiping choice than water. Put a little chalk on a piece of scrap and try removing it with the alcohol to make sure it works next time. You can find denatured alcohol at home centers and paint stores.
