I just don't remember so we slowly poured a cup of luke-warm water on our car windows this morning. We're a little frost illiterate here in Southern California. Or perhaps it's just me. There's already a crack in the front window so we didn't want to have it implode from the frost. Anyhow, is it hot, luke-warm, or cold water we pour on frozen windows.
