If you want to remove Sharpie, use IPA...isopropyl alcohol...India pale ale remains useless.
Isopropyl removes all inks and glues. It's incredible. It's also fantastic to wash your hands with when doing cell and tissue cultures and trying to avoid contamination.

Slightly off topic, but if you ever write on a whiteboard with a sharpie, you can write over the text with an erasable marker and then wipe it away.

I recommend chalk. Its a little dusty but works great. Seems to be nontoxic and low in the chemicals and plastic department. Chalk. Even comes in colors. I'm not joking.
Also it's actually gypsum. Same material plaster and plasterboard is made from.
> Chalk sticks are produced in white and in various colours, especially for use with blackboards. White chalk sticks are made mainly from calcium carbonate derived from mineral chalk or limestone, while coloured chalk sticks are made from calcium sulphate in its dihydrate form, CaSO4·2H2O, derived from gypsum.[6][7] Chalk sticks containing calcium carbonate typically contain 40–60% of CaCO3 (calcite).

Wikipedia cites the following articles:

The first of these seems more relevant... I'm not quite sure what the second citation adds.
If you can do VR whiteboard it's probably the best option.
I dont understand why anyone would use chalk.
Get a real blackboard made of slate and quality chalk. Much higher resolution than markers.
> some kind of magnetic board Sounds like a giant Etch-a-sketch? There are these small electric blackboards that you can push a button to reset: https://myboogieboard.com/pages/blackboard-smart I wonder if they make a giant wall mountable version?
I don't think I realized how often I need to erase or update a small section of a list or diagram without erasing the entire thing until using these.
