Be careful that you don’t allow the insert to become unhinged when you open it enough to clean. I find them to be a huge pain to put back together completely after it’s come apart. Let the string do its job of keeping the window from coming apart.
If you are taking the blinds out, don’t count on the little pull loop (which I think is labeled “B”) on the blind’s frame to actually be secure enough to pull on. I raise the blinds and then pull the bottom of the frame with my thumb and the loop with finger, so that all the force isn’t on the loop.
Also, when you put the blinds back in, the tab (I think it’s labelled “A”) that slides into the hole in the window frame opening (Which turns the mechanism to raise and lower the blind) sometimes doesnt seem to line back up properly with the hole. As you push the tab back into the hole, you may need to raise/lower the lever for the blinds. That will turn the hole so it lines back up with the tab.
And I find it easier to clean the exposed side last, so that I can push it back shut without worrying about getting finger prints on it.
I hope it’s hot where you’re working and you get to enjoy a LONG time in the A/C working on these
