Writing on fumehood sash
I, like many people, like to draw my reaction structures down in front of me when experimenting, and I have noticed that professional labs just write
with whiteboard markers on their glass fumehood sashes. My fume hood, however, has an acrylic sash and this this type of pen is not appropriate. Can
anyone suggest an alternative - i.e., an erasable pen for acrylic?

You might consider laminating some glass to the front surface of your sash. I haven't tried it yet (though
it's on my list), but I'm fairly sure that water-thin cyanoacrylates would work just fine as a laminating glue. Plastic-glass laminates are the
essence of safety glass already. The limiting factor is how cheap and easy it can be done OTC.

A dry erase marker should work just fine on acrylic.

No, I have tried it and it stays on forever, short of using acetone or another solvent on it.

Grease pens, as GteenD said. We use in porous tile at work because the dry erase gets into the pores. You'll still need a cleaner, like isopropyl
alcohol, but a dry sponge or scrub pad gets 95% of in just a few wipes. Ill post a pic when I get to work tonight of what I use. They are cheap.

They are great, about as opaque as you can get.
