Something I always forget when driving

You don't really notice it normally, but
occasionally when driving directly into the sunlight,
the smudge marks and streaks on the inside of the window become glaringly obvious.
It's a constant, subtle distraction while driving.
Ideally, you could just leave it alone after getting a professional hand wash,
but when something gets on it and you try to wipe it off roughly with a tissue,
the wipe marks stay right there.
I tell myself I'll clean it properly later,
but since the sunlight isn't always hitting the window directly while driving,
I can't see the dirt,
so I end up forgetting that I meant to clean it later.
Then the next day, when the sunlight hits it directly again,
I think, "Ah, I should have wiped that..."
It's a daily cycle..
I've been doing that for a month,
but today I went to Daiso, bought some glass cleaner and a microfiber glass cloth, and wiped it down lol.
Man, it feels so refreshing.
