Many people think about how to wash windows, and not when to do it. Although this factor must be taken into account. It is best to do this when direct sunlight does not fall on the glass, but there is enough light outside. Suitable early morning, time before sunset, cloudy day. Otherwise, because of the sun, the cleaning solutions will dry out faster than you can wipe them, and you won’t be able to wash the windows without streaks on the glass. Amruss windows surely knows it.
It's also worth checking the weather forecast and postponing washing if it's going to rain. Or, in this case, limit yourself to wiping the windows from the inside.
