Ha! We have similar windows. My MIL completely cleaned them inside and out when we moved in. She stood on our porch roof! She was something back then. They haven’t been cleaned since. We moved in in 2006! I’ll half heartedly clean what I can every now and then, but the shutters stay shut pretty much all the time.
Drafts. Yup have them too. I have some stuffed animal snakes that the kids won at Busch Gardens stuffed against some double French doors to the screened in porch.
