Halocho #1489 - Foggy windows on Shabbat

Writing and drawing is forbidden on Shabbat - even if it's temporary.

One may not use one's finger to write or draw on the condensation of a window.

One may not write nor draw using water that spilled on a table.

One may not use one's nail to make a mark on page, to enable one to find the place again, or for any other reason.
