Can I draw on glass with acrea and then remove the ink later?

"Yes. You can use the acrea ink on smooth surfaces such as glass or mirrors. Since acrea ink does not soak into these surfaces, you can remove it with wet wipes or a window cleaner. Keep in mind, however, that the longer the ink remains on the surface, the more difficult it may be to remove. Even after wiping off the ink, some traces of the drawing may remain, so it is recommended to test before use."
