I know nothing about science ........ dropped it asap at school, and since Tomorrow's World stopped being aired on BBC1 a few decades ago I just have to blindly trust that things just happen! PS Useful background info - I have no extractor fan, and often cut myself shaving due to a steamed up mirror!

Variations in ambient temperature does it.

You really should have maintained the science classes. If the mirror is cool, compared to the "steam' which is only water vapor from the shower, the moisture will condense on it. This makes the mirror appear to be "steamed up". If it were real steam, you'd make a fast dash out of the shower like a scalded dog, because that is exactly what you would be, scalded. If the mirror is warm, then the mirror will not have water condensing on it. Basic science, see, you should have stuck it out. A fine, very thin coating of oil on the mirror will keep it from "steaming up".

Condensation will form on your mirror whenever your mirror is cool enough relative to the moist air to remove enough heat to lower the air to its dew point. If you take a cold shower no condensation will form while a hot shower will evaporate far more vapor and form lots of condensation. If the mirror is warm it will avoid condensation but if it is cold it will form lots of condensation. Condensation forms more easily in the winter than the summer. Also if the air is initially very dry it will take longer to form condensation which can depend on how long you shower. If you adjust the shower temperature to slightly warm and take a brief shower you can minimize condensation without more ventilation.

Assuming you're taking bath in the same setting everyday, this difference maybe due to the temperature of the mirror. If it's warmer, it'll be harder for the steam to condense. if it's colder, it'll be all the more easier.

The colder the surface of the mirror compared to the ambient temp will increase the amount of condensation that forms.

it all depends on the temperature of the room, and therefore of the mirror, a cold room and you get the steam condensing out on the cold surface of the mirror, a warm room and it doesn't as the temperature difference isn't enough, it's like when you breathe out on a cold day you can see your breath as a cloud of condensation, on a warm day you don't see it.

Is it that on days it does not steam up you have a window open or the extracter fan on

condensation will be worse if you have very hot water running and the window closed,also probably worse in cold weather with hot water running and no ventilation.
